Comments about recent Semantic Gang Podcast
http://www.openlinksw.com/blog/~kidehen/?id=1357
2008-05-02T21:44:31Z
<p>After listening to the <a href="http://semanticgang.talis.com/2008/05/02/april-2008-the-semantic-web-gang-discuss-a-wikipedia-for-data/" id="link-id1089e218">latest Semantic Web Gang podcast</a>, I found myself agreeing with some of the points made by <a href="http://www.linkedin.com/in/iskold" id="link-id10b91e58">Alex Iskold</a>, specifically: </p> <ul>-- <a href="http://dbpedia.org/resource/Linked_Data" id="link-id106e24e0">Linked Data</a> does not implicitly imply making all your <a href="http://dbpedia.org/resource/Data" id="link-id17ab3d48">data</a> public</ul> <ul>-- <a href="http://dbpedia.org/resource/Linked_Data" id="link-id11fdcef0">Linked Data</a> principles benefit <a href="http://dbpedia.org/resource/Intranet" id="link-id109756e8">Intranet</a> and <a href="http://dbpedia.org/resource/Extranet" id="link-id1099cfd8">Extranet</a> style <a href="http://dbpedia.org/resource/Data" id="link-id10cd25b0">data</a> integration (trumps alternative <a href="http://dbpedia.org/resource/federated_database_system" id="link-id14f29940">distributed database</a> integration approaches any day)</ul> <ul>-- Business exploitation of <a href="http://dbpedia.org/resource/Linked_Data" id="link-id0xca51940">Linked Data</a> on the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> will certainly be driven by the correlation of opportunity costs (which is more than likely what Alex meant by "use cases") associated with the lack of URIs originating from the domain of a given business (Tom Heath: also effectively alluded to this via his <a href="http://dbpedia.org/resource/BBC" id="link-id16f33348">BBC</a> and <a href="http://dbpedia.org/resource/Uniform_Resource_Identifier" id="link-id10decf38">URI</a> land grab anecdotes; same applies Georgi's examples)</ul> <ul>-- History is a great tutor, answers to many of today's problems always lie somewhere in plain sight of the past.</ul> <p>Of course, I also believe that <a href="http://dbpedia.org/resource/Linked_Data">Linked Data</a> serves Web <a href="http://dbpedia.org/resource/Data" id="link-id0x1afebd58">Data</a> Integration across the <a href="http://dbpedia.org/resource/Internet" id="link-id10aa5668">Internet</a> very well too, and the fact that it will be beneficial to businesses in a big way. No individual or organization is an island, I think the <a href="http://dbpedia.org/resource/Internet" id="link-id0xb25fbd0">Internet</a> and Web have done a good job of demonstrating that thus far :-) We're all <a href="http://dbpedia.org/resource/Data">data</a> nodes in a <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id5d8a3a8">Giant Global Graph</a>.</p> <p> <a href="http://myopenlink.net/dataspace/person/danieljohnlewis#this" id="link-id17cac8a0">Daniel lewis</a> did shed light on the read-write aspects of the Linked Data <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id10be8590">Web</a>, which is actually very close to the callout for a Wikipedia for Data. <a href="http://www.w3.org/People/Berners-Lee/card#i" id="link-id10a810c0">TimBL</a> has been working on this via <a href="http://dig.csail.mit.edu/2005/ajar/release/tabulator/0.8/tab.html" id="link-id184b7108">Tabulator</a> (see <a href="http://dig.csail.mit.edu/2007/tab/tutorial/editing.mov" id="link-id1416f1e8">Tabulator Editing Screencast</a>), <a href="http://bnode.org/about" id="link-id17e33750">Bengamin Nowack</a> also added <a href="http://arc.semsol.org/download/plugins/data_wiki" id="link-id1688cc40">similar functionality to ARC</a>, and of course we support the same <a href="http://dbpedia.org/resource/SPARQL" id="link-id10bff7c8">SPARQL</a> UPDATE into an <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id168ace08">RDF</a> <a href="http://dbpedia.org/resource/Information" id="link-id10641878">information</a> resource via the <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id0xddb5240">RDF</a> Sink feature of our WebDAV and <a href="http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/OdsBriefcase" id="link-id0x11199310">ODS</a>-Briefcase implementations.</p>

In Perpetual Pursuit of Context
http://www.openlinksw.com/blog/~kidehen/?id=1356
2008-05-02T19:18:33Z
<p>I've always been of the opinion that concise value proposition articulation shouldn't be the achilles of the <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id158efe90">Semantic Web</a>. As the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id13a2db40">Linked Data</a> wave climbs up the "value Appreciation and Comprehension chain", it's getting clearer by the second that "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id109316f0">Context</a>" is a point of confluence for <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id108daa60">Semantic Web</a> Technologies and easy to comprehend value, from the perspectives of those outside the core community.</p> <p>In today's primarily Document centric <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a>, the pursuit of <a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id14edadd0">Context</a> is akin to pursuing a mirage in a desert of user generated content. The quest is labor intensive, and you ultimaely end up without water at the end of the pursuit :-)</p> <p>Listening to the <a href="http://blogs.talis.com/nodalities/2008/05/christine-connors-talks-about-semantic-technologies-at-dow-jones.php" id="link-id12d5e1c0">Christine Connor's podcast interview with Talis</a> simply reinforces my strong belief that "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id0x1ec69518">Context</a>, Context, Context" is the <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id0xa279438">Semantic Web</a>'s equivalent of Real Estate's "Location, Location, Location" (ignore the <a href="http://dbpedia.org/resource/Subprime_lending" id="link-id140b8098">subprime</a> loans mess for now). The critical thing to note is that you cannot unravel "Context" from existing Web content without incorporating powerful disambiguation technology into an "<a href="http://dbpedia.org/resource/Entity" id="link-id15a2f380">Entity</a> Extraction" process. Of course, you cannot even consider seriously pursing any <a href="http://dbpedia.org/resource/Entity" id="link-id10868a18">entity</a> extraction and disambiguation endeavor without a lookup backbone that exposes "<a href="http://dbpedia.org/resource/Named_entity_recognition" id="link-id168dc230">Named Entities</a>" and their relationships to "<a href="http://dbpedia.org/resource/Topic" id="link-id17cb1950">Subject matter Concepts</a>" (BTW - this is what <a href="http://umbel.org/about/" id="link-id14f406a0">UMBEL</a> is all about). Thus, when looking at the broad subject of the <a href="http://dbpedia.org/resource/Semantic_Web">Semantic Web</a>, we can also look at "Context" as the vital point of confluence for the <a href="http://dbpedia.org/resource/Data" id="link-id12d67e38">Data</a> oriented (<a href="http://dbpedia.org/resource/Linked_Data" id="link-id14f8daf0">Linked Data</a>) and the "Linguistic Meaning" oriented perspectives.</p> <p>I am even inclined to state publicly that "Context" may ultimately be the foundation for <a href="http://www.openlinksw.com/weblog/public/search.vspx?blogid=127&q=dimension%20web%204.0%20&type=text&output=html" id="link-id17cb0708">4th "Web Interaction Dimension"</a> where practical use of <a href="http://dbpedia.org/resource/Artificial_intelligence" id="link-id10b15088">AI</a> leverages a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id0x1ebf9310">Linked Data</a> <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id10b27018">Web</a> substrate en route to exposing new kinds of value :-)</p> <p>"Context" may also be the focal point of concise value proposition articulation to <a href="http://dbpedia.org/resource/Venture_Capital" id="link-id10837578">VCs</a> as in: "My solution offers the ability to discover and exploit "Context" iteratively, at the rate of $X.XX per iteration, across a variety of market segments :-)</p>

Linked Data enters state of Evoluation
http://www.openlinksw.com/blog/~kidehen/?id=1351
2008-04-29T19:56:14Z
<p>During a brief chat with <a href="http://community.linkeddata.org/dataspace/person/mhausenblas#this" id="link-idfeb0100">Michael Hausenblas</a> about a new <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1049feb0">Linked Data</a> project he is championing called: <a href="http://esw.w3.org/topic/SweoIG/TaskForces/CommunityProjects/LinkingOpenData/LForum" id="link-id16a857d8">LForum</a>, I made a freudian slip, in the form of the typo: <strong>Evoluation</strong>, which at the time was supposed to have been: <strong>Evolution</strong>. Anyway, we had a chuckle and realized we were on to something, so I proceeded to formalize the definition: </p> <blockquote> <cite>Evoluation is evolution devoid of the randomness of mutation. A state of being in which it is possible to evaluate and choose evolutionary paths.</cite> </blockquote> <p> <strong>Evoluation</strong> actually describes where we are today in relation to the <a href="http://dbpedia.org/resource/World_Wide_Web" id="link-id105c1518">World Wide Web</a>; to the <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id103f9d00">Linking Open Data community</a> (<a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id1048c210">LOD</a>), it's taking the path towards becoming a <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id104c3a20">Giant Global Graph</a> of <a href="http://dbpedia.org/resource/Linked_Data" id="link-id104968e0">Linked Data</a>; to the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> 2.0 community, it's simply a collection of Web Services and associated APIs; and to many others, it remains an opaque collection of interlinked documents.</p> <p>The great thing about the Web is that it allows netizens to explore a plethora of paths without adversely affecting the paths of others. That said, controlling one's path may take mutation out of evolution, but we are still left with the requirement to adapt and eventually survive in a competitive environment. Thus, although we can evaluate and choose from the many paths the Web's evolution offers us, the path that delivers the most benefits ultimately dominates. :-) </p>

Linked Data Trip Report - Part 1 (Update 2)
http://www.openlinksw.com/blog/~kidehen/?id=1343
2008-04-28T18:48:33Z
<p>Typo cleansed edition :-)</p> <h2>Objectives</h2> <ul> <li>Meet <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id12c52e40">LOD</a> Community Members</li> <li>Participate in Workshop </li> </ul> <h3>Meeting <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id10456058">LOD</a> Community Members</h3> <p>Although the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> continues to shrink the planet by removing the restrictions of geopgrahic location, meeting people face-to-face remains invaluable (*priceless in Mastercard AD speak*). Naturally, meeting and chatting with as many <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id1382d4f8">LOD</a> community members as possible was high up on my agenda.</p> <h3>Participate in Workshop </h3> <p>As one of the co-chairs of the Linking Open <a href="http://dbpedia.org/resource/Data" id="link-id143a8c30">Data</a> Workshop (<a href="http://events.linkeddata.org/ldow2008/" id="link-id10621d70">LODW</a>), I had a 5 minute workshop opening slot during which I spoke about the following:</p> <h4>Where we are today: </h4> <p>We have <a href="http://dbpedia.org/resource/DBpedia" id="link-id109b40a0">DBpedia</a> as a major hub on the burgeoning <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1074f248">Linked Data</a> <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id101ed948">Web</a>. When OpenLink offered to host <a href="http://dbpedia.org/resource/DBpedia" id="link-id10cd1b20">DBpedia</a> (a combination of <a href="http://virtuoso.openlinksw.com" id="link-id13d19880">Virtuoso</a> DBMS Software and sizable backend Hardware infrastructure), it did so knowing that such an effort would emphatically address the "chicken and egg" conundrum that, prior to this undertaking, stifled the ability to demonstrate practical utility of <a href="http://dbpedia.org/resource/Hypertext_Transfer_Protocol" id="link-id13835980">HTTP</a> based <a href="http://dbpedia.org/resource/Linked_Data" id="link-id14a89c28">Linked Data</a>.<br /> <br /> Today, the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10aa9fe0">Linked Data</a> bootstrap mission has been accomplished.</p> <h4>Where we go next:</h4> <p>Although <a href="http://dbpedia.org/resource/DBpedia" id="link-id12fe5d98">DBpedia</a> is a hub (ground zero of <a href="http://dbpedia.org/resource/Linked_Data" id="link-id14aca9b8">Linked Data</a>), we have to put it into perspective in relation to a new set of needs and expectations moving forward. Today, <a href="http://dbpedia.org/resource/DBpedia" id="link-id1027f098">DBpedia</a> is a Sun at the heart of a Solar System within the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id14a6adf8">Linked Data</a> Galaxy. But unlike Space as we know it, in <a href="http://dbpedia.org/resource/Cyberspace" id="link-id14a80398">Cyberspace</a> we can have connectivity and collaboration across Solar Systems -- life exists elsewhere and we are part of a collaborative collective unimpeded by constraints of space travel etc. Thus, expect to see the emergence of other Solar Systems accessible to <a href="http://dbpedia.org/resource/DBpedia" id="link-id14904998">DBpedia</a> and its collections of planets (see. <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id1097d200">LOD</a> <a href="http://richard.cyganiak.de/2007/10/lod/" id="link-id14acecf0">diagram</a>).

Of course, I encouraged all presenters to make this an integral part of their presentations :-) </p> <h4>Workshop Summary: </h4> <p>The workshop was well attended and I found all the presentations engaging and full of enthusiasm. </p> <p>As the sessions progressed, it became clear during a number of accompanying Q&A sessions that a new <a href="http://dbpedia.org/resource/Linked_Data" id="link-idff249b0">Linked Data</a> exploitation frontier is emerging. The frontier in question takes the form of a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10f73b50">Linked Data</a> substrate capable of addressing the taxonomic needs of solutions aimed at automated <a href="http://dbpedia.org/resource/Named_entity_recognition" id="link-id10d16e00">Named Entity Extraction</a>, Disambiguation, Subject matter Concept alignment, transparently integrated with existing Web Content. Thus, we are moving beyond the minting and deployment of of dereferencable URIs and <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id10419210">RDF</a> <a href="http://dbpedia.org/resource/Data" id="link-id151520d0">data</a> sets to automagically associating existing Web Content with <a href="http://dbpedia.org/resource/Named_entity_recognition" id="link-id105573b0">Named Entities</a> (People, Organizations, Places, Events etc..) and Subject matter Concepts (Politics, Music, Sports, and others) while remaining true to the <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id14579108">Linking Open Data Community</a> creed i.e. ensuring the Named <a href="http://dbpedia.org/resource/Entity" id="link-id147d31e8">Entity</a> and Subject matter Concept URIs are available to user agents or users seeking to produce alternative <a href="http://dbpedia.org/resource/Data" id="link-id14ae41f0">data</a> views (i.e. Mesh-ups).</p> <p>I will get to part 2 of this report once the actual workshop sessions slides go live (*these are different from the <a href="http://events.linkeddata.org/ldow2008/" id="link-id1034eee8">pre-event PDFs links</a>*).</p>

Linked Data Illustrated and a Virtuoso Functionality Reminder

<a href="http://myopenlink.net/dataspace/person/danieljohnlewis#this" id="link-id156ceb30">Daniel Lewis</a> has put together a nice <a href="http://vanirsystems.com/danielsblog/2008/04/27/linked-data-the-role-of-the-data-server/" id="link-id10456040">collection of Linked Data related posts</a> that illustrate the fundamentals of the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1033f6f0">Linked Data</a> <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id106fa168">Web</a> and the vital role that <a href="http://virtuoso.openlinksw.com" id="link-id10141c20">Virtuoso</a> plays as a deployment platform. Remember, <a href="http://virtuoso.openlinksw.com" id="link-id10301e38">Virtuoso</a> was architected in 1998 (see <a href="http://virtuoso.openlinksw.com/wiki/main/Main/VOSHistory" id="link-id10c44088">Virtuoso History</a>) in anticipation of the eventual <a href="http://dbpedia.org/resource/Internet" id="link-id1383a1e8">Internet</a>, <a href="http://dbpedia.org/resource/Intranet" id="link-id1028e770">Intranet</a>, and <a href="http://dbpedia.org/resource/Extranet" id="link-id14b07b40">Extranet</a> level requirements for a different kind of Server. At the time of <a href="http://virtuoso.openlinksw.com" id="link-id14ad24a8">Virtuoso</a>'s inception, many thought our desire to build a multi-protocol, multi-model, and multi-purpose, virtual and native <a href="http://dbpedia.org/resource/Data" id="link-id108dac48">data</a> server was sheer craziness, but we pressed on (courtesy of our vision and technical capabilities). Today, we have a very sophisticated <a href="http://dbpedia.org/resource/Virtuoso_Universal_Server" id="link-id14a65d48">Universal Server</a> Platform (in Open Source and Commercial forms) that is naturally equipped to do the following via very simple interfaces: <ul> - Produce <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id11fb1170">RDF</a> <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10871da8">Linked Data</a> from non <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id156ec3d0">RDF</a> <a href="http://dbpedia.org/resource/Data" id="link-id10f0ca38">Data</a> Sources (Heterogeneous <a href="http://dbpedia.org/resource/SQL" id="link-id15133078">SQL</a>, XML, <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> Services)</ul> <ul> - Provide highly scalable <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id10585940">RDF</a> <a href="http://dbpedia.org/resource/Data" id="link-id15151e10">Data</a> Management via a Quad Store (<a href="http://dbpedia.org/resource/DBpedia" id="link-id1530d640">DBpedia</a> is an example of a live demonstration)</ul> <ul> - Sophisticated Deployment of <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10141c80">Linked Data</a> that exploits the power of <a href="http://dbpedia.org/resource/SPARQL" id="link-id1064fa18">SPARQL</a> </ul> <ul> - Powerful WebDAV innovations that simplify read-write mode interaction with <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1396ff68">Linked Data</a> </ul> <ul> - Use Web <a href="http://dbpedia.org/resource/Federated_database_system" id="link-id108256e8">Data Virtualization</a> to address the pain and frustration associated with Web <a href="http://dbpedia.org/resource/Data" id="link-id147e65f8">Data</a> Silos (e.g. <a href="http://dbpedia.org/resource/OpenLink_Data_Spaces" id="link-idffaf078">OpenLink Data Spaces</a> layer stop <a href="http://virtuoso.openlinksw.com" id="link-id14ae8fe8">Virtuoso</a> that delivers <a href="http://dbpedia.org/resource/OpenLink_Data_Spaces" id="link-id0xa0fb5e40">Personal Data Spaces</a> / Unified Storage in the Clouds) </ul> <ul> - Deliver a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10869700">Linked Data</a> development and deployment platform to .<a href="http://dbpedia.org/resource/.NET_Framework" id="link-id1514cac0">NET</a> (<a href="http://dbpedia.org/resource/Visual_Basic" id="link-id10c107a8">VB</a>, <a href="http://dbpedia.org/resource/C_(programming_language)" id="link-id101f3c68">C</a>#) , Java, <a href="http://dbpedia.org/resource/PHP" id="link-id106e4710">PHP</a>, <a href="http://dbpedia.org/resource/Ruby_programming_language" id="link-id10277448">Ruby</a>, <a href="http://dbpedia.org/resource/Perl" id="link-id10a75748">Perl</a>, <a href="http://dbpedia.org/resource/Python_programming_language" id="link-id12fdb118">Python</a>, '<a href="http://dbpedia.org/resource/C_(programming_language)" id="link-id10c9d9e0">C</a>', <a href="http://dbpedia.org/resource/C%2B%2B" id="link-id10392400">C++</a>, and other developers </ul> <ul>- More...</ul>

Explaining the Granular Social Network

<p>Courtesy of <a href="http://www.vimeo.com/user321809/l:embed_898144" id="link-id10c725a8">Thomas Vander Wal</a>'s interesting <a href="http://dbpedia.org/resource/Blog" id="link-id142dfb90">blog</a> post titled: Explaining the Granular Social Network, I found a nice video that highlights the Who + What you know aspect of Social Networking ad the <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id1054bc58">GGG</a> in general. </p> <p>As I can't quite remix Videos on the spur of the moment (yet), I would encourage you to watch the video and then click on the link to <a href="http://myopenlink.net/dataspace/person/kidehen" id="link-id130b7410">my FOAF Profile</a>, then follow the "<a href="http://dbpedia.org/resource/Linked_Data" id="link-id18485a48">Linked Data</a>" tab to see how <a href="http://dbpedia.org/resource/Linked_Data" id="link-id14070380">Linked Data</a> oriented platforms (in my case <a href="http://dbpedia.org/resource/OpenLink_Data_Spaces" id="link-id10a30f60">OpenLink Data Spaces</a>) that exist today actually deliver what's explained in the video. </p> <p>"What You Know" (<a href="http://www.jasonkolb.com/weblog/2008/03/users-as-data-c.html" id="link-id140f4e28">Data & Friend Networks</a>) ultimately trumps "Who You Know" (Friend only Networks).

The Cost of doing the Right Thing
http://www.openlinksw.com/blog/~kidehen/?id=1330
2008-03-27T18:41:43Z
<p>One of the biggest impediments to the adoption of technology is the cost burden typically associated with doing the right thing. For instance, requirements for making the <a href="http://dbpedia.org/resource/Linked_Data">Linked Data</a> <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> (<a href="http://dbpedia.org/resource/Giant_Global_Graph">GGG</a>) buzz would include the following (paraphrasing <a href="http://www.w3.org/People/Berners-Lee/card#i">TimBL</a>'s original <a href="http://www.w3.org/DesignIssues/LinkedData.html">Linked Data meme</a>): </p> <ul>-- identifying the things you observe, or stumble upon, using URIs (aka <a href="http://dbpedia.org/resource/Entity">Entity</a> IDs)</ul> <ul>-- construct URIs using <a href="http://dbpedia.org/resource/Hypertext_Transfer_Protocol">HTTP</a> so that the Web provides a channel for referencing things elsewhere (remote object referencing)</ul> <ul>-- Expose things in your <a href="http://dbpedia.org/resource/Data">Data</a> <a href="http://en.wikipedia.org/wiki/Data_Spaces">Space</a>(s) that are potentially useful to other Web users via URIs</ul> <ul>-- Link to other Web accessible things using their URIs.</ul> <p>The list is nice, but actual execution can be challenging. For instance, when writing a <a href="http://dbpedia.org/resource/Blog">blog</a> post, or constructing a <a href="http://dbpedia.org/resource/WikiWord">WikiWord</a>, would you have enough disposable time to go searching for these URIs? Or would you compromise and continue to inject "Literal" values into the Web, leaving it to the reasoning endowed human reader to connect the dots?</p> <p>Anyway, <a href="http://dbpedia.org/resource/OpenLink_Data_Spaces">OpenLink Data Spaces</a> is now equipped with a <a href="http://dbpedia.org/resource/Glossary">Glossary</a> system that allows me to manage terms, meaning of terms, and hyper-linking of phrases and words matching associated with my terms. The great thing about all of this is that everything I do is scoped to <a href="http://myopenlink.net/dataspace/kidehen">my Data Space</a> (my universe of discourse), I don't break or impede the other meanings of these terms outside my Data Space. The Glossary system can be shared with anyone I choose to share it with, and even better, it makes my upstreaming (rules based replication) style of blogging even more productive :-) </p> <p>Remember, on the Linked Data Web, who you know doesn't matter as much as what your are connected to, directly or indirectly. <a href="http://www.jasonkolb.com/">Jason Kolb</a> covers this issue in his post: <a href="http://www.jasonkolb.com/weblog/2008/03/users-as-data-c.html" id="link-id1586a468">People as Data Connectors</a>, and so doesFrederick Giasson via a recent post titled: <a href="http://fgiasson.com/blog/index.php/2008/03/11/networks-are-everywhere/" id="link-id108b9010">Networks are everywhere</a>. For instance, this blog post (or the entire Blog) is a bona fide <a href="http://dbpedia.org/resource/Resource_Description_Framework">RDF</a> Linked Data Source, you can use it as the Data Source of a <a href="http://dbpedia.org/resource/SPARQL">SPARQL</a> Query to find things that aren't even mentioned in this post, since all you are doing is beaming a query through my Data Space (a container of Linked Data Graphs). On that note, let's re-watch <a href="http://blog.jonudell.net/">Jon Udell</a>'s <a href="http://weblog.infoworld.com/udell/gems/queryingBlogs.html" id="link-id108c0908">"On-Demand-Blogosphere" screencast from 2006</a> :-)</p>

Semantic Web Patterns: A Guide to Semantic Technologies (Update 2)
http://www.openlinksw.com/blog/~kidehen/?id=1329
2008-03-27T00:08:13Z
<p>For all the one-way feed consumers and aggregators, and readers of the original post, here is a variant equipped hyperlinked phrases as opposed to words. As I stated in the prior post, the post (like most of my posts) was part experiment / dog-fodding of automatic tagging and hyper-linking functionality in <a href="http://dbpedia.org/resource/OpenLink_Data_Spaces">OpenLink Data Spaces</a>. </p> <p> <a href="http://www.readwriteweb.com">ReadWriteWeb</a> via <a href="http://alexiskold.wordpress.com/" id="link-id154ae848">Alex Iskold's post</a> have delivered another iteration of their "Guide to Semantic Technologies".</p> <p>If you look at the title of this post (and <a href="http://feeds.feedburner.com/~r/readwriteweb/~3/257943334/semantic_web_patterns.php" id="link-id10a9a900">their article</a>) they seem to be accurately providing a guide to Semantic Technologies, so no qualms there. If on the other hand, this is supposed to he a guide to the "<a href="http://dbpedia.org/resource/Semantic_Web">Semantic Web</a>" as prescribed by <a href="http://www.w3.org/People/Berners-Lee/card#i">TimBL</a> then they are completely missing the essence of the whole subject, and demonstrably so I may add, since the entities: "ReadWriteWeb" and "<a href="http://www.linkedin.com/in/iskold">Alex Iskold</a>" are only describable today via the attributes of the documents they publish i.e their respective blogs and hosted blog posts.</p> <blockquote> <p>Preoccupation with Literal objects as describe above, implies we can only take what "ReadWriteWeb" and "Alex Iskold" say "Literally" (<a href="http://dbpedia/resource/Grep">grep</a>, <a href="http://dbpedia.org/resource/regular_expression">regex</a>, and <a href="http://dbpedia.org/resource/XPath">XPath</a>/<a href="http://dbpedia.org/resource/XQuery">Xquery</a> are the only tools for searching deeper in this Literal realm), we have no sense of what makes them tick or where they come from, no history (bar "About Page" blurb), no <a href="http://dbpedia.org/resource/Data">data</a> connections beyond anchored text (more pointers to opaque data sources) in post and blogrolls. The only connection between this post and them is the my deliberate use of the same literal text in the Title of this post.</p> </blockquote> <p>TimBL's vision as espoused via the "Semantic Web" vision is about the production, consumption, and sharing of Data Objects via HTTP based Identifiers called URIs/IRIs (<a href="http://dbpedia.org/resource/Linked_Data">Hyperdata</a> Links / <a href="http://dbpedia.org/resource/Linked_Data">Linked Data</a>). It's how we use the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> as a <a href="http://dbpedia.org/resource/federated_database_system">Distributed Database</a> where (as <a href="http://www.cs.umd.edu/~hendler/2003/foaf.rdf#jhendler">Jim Hendler</a> once stated with immense clarity): I can point to records (<a href="http://dbpedia.org/resource/Entity">entity</a> instances) in your database (aka Data Space) from mine. Which is to say that if we can all point to data entities/objects (not just data entities of type "Document") using these Location, Value, and Structure independent Object Identifiers (courtesy of HTTP) we end up with a much more powerful Web, and one that is closer to the "Federated and Open" nature of the Web.</p> <p>As I stated in a prior post, if you or your platform of choice aren't producing de-referencable URIs for your data objects, you may be Semantic (this data model predates the Web), but there is no "World Wide Web" in what you are doing.</p> <h2>What are the Benefits of the Semantic Web?</h2> <ul> <strong>Consumer</strong> - "Discovery of relevant things" and be being "Discovered by relevant things" (people, places, events, and other things)</ul> <ul> <strong>Enterprise</strong> - ditto plus the addition of enterprise domain specific things such as market opportunities, product portfolios, human resources, partners, customers, competitors, co-opetitors, acquisition targets, new regulation etc..)</ul> <h2>Simple demo:</h2> <blockquote> <p>I am a <a href="http://myopenlink.net/dataspace/person/kidehen#this">Kingsley Idehen</a>, a Person who authors <a href="http://www.openlinksw.com/blog/~kidehen">this weblog</a>. I also share bookmarks gathered over the years across an array of subjects via <a href="http://myopenlink.net/dataspace/kidehen/bookmark/KingsleyBookmarks">my bookmark data space</a>. I also subscribe to a number of RSS/Atom/<a href="http://dbpedia.org/resource/Resource_Description_Framework">RDF</a> feeds, which I share via my feeds subscription data space. Of course, all of these data sources have Tags which are collectively exposed via my <a href="http://myopenlink.net/dataspace/kidehen/weblog/MyBlogDataSpace/tagcloud">weblog tag-cloud</a>, feeds subscriptions <a href="http://dbpedia.org/resource/Tag">tag</a>-cloud, and <a href="http://myopenlink.net/dataspace/kidehen/bookmark/KingsleyBookmarks/tagcloud">bookmarks tag-cloud</a> data spaces.</p> <p>As I don't like repeating myself, and I hate wasting my time or the time of others, I simply share <a href="http://myopenlink.net/dataspace/kidehen">my Data Space</a> (a collection of all of my purpose specific data spaces) via the Web so that others (friends, family, employees, partners, customers, project collaborators, competitors, co-opetitors etc.) can can intentionally or serendipitously discover relevant data en route to creating new <a href="http://dbpedia.org/resource/Information">information</a> (perspectives) that is hopefully exposed others via the Web.</p> </blockquote> <p>Bottom-line, the Semantic Web is about adding the missing "Open Data Access & Connectivity" feature to the current Document Web (we have to beyond regex, grep, xpath, xquery, <a href="http://dbpedia.org/resource/Full_text_search">full text search</a>, and other literal scrapping approaches). The Linked Data Web of de-referencable data object URIs is the critical foundation layer that makes this feasible.</p> <p> Remember, It's not about "Applications" it's about Data and actually freeing Data from the "tyranny of Applications". Unfortunately, application inadvertently always create silos (esp. on the Web) since entity data modeling, open data access, and other database technology realm matters, remain of secondary interest to many application developers.</p> <p>Final comment, RDF facilitates Linked Data on the Web, but all RDF isn't endowed with de-referencable URIs (a major source of confusion and misunderstanding). Thus, you can have RDF Data Source Providers that simply project RDF data silos via Web Services APIs if RDF output emanating from a Web Service doesn't provide out-bound pathways to other data via de-referencable URIs. Of course the same also applies to Widgets that present you with all the things they've discovered without exposing de-referencable URIs for each item.</p> <p>BTW - my final comments above aren't in anyway incongruent with devising successful business models for the Web. As you may or may not know, OpenLink is not only a major platform provider for the Semantic Web (expressed in our UDA, Virtuoso, OpenLink Data Spaces, and OAT products), we are also actively seeding Semantic Web (tribe: Linked Data of course) startups. For instance, Ztigist, which now has <a href="http://community.linkeddata.org/dataspace/person/mkbergman#this">Mike Bergman</a> as it's CEO alongside <a href="http://fgiasson.com/me/">Frederick Giasson</a> as CTO. Of course, I cannot do <a href="http://zitgist.com/about/">Zitgist</a> justice via a footnote in a blog post, so I will expand further in a separate post.</p> <h2>Additional information about this blog post: </h2> <ol> <li> I didn't spent hours looking for URIs used in my hyperlinks</li> <li> The post is best viewed via an RDF Linked Data aware user agents (<a href="http://demo.openlinksw.com/rdfbrowser">OpenLink RDF Browser</a>, Zitgist <a href="http://dataviewer.zitgist.com">Data Viewer</a>, <a href="http://www4.wiwiss.fu-berlin.de/rdf_browser">DISCO Hyperdata Browser</a>, <a href="http://dig.csail.mit.edu/2005/ajar/release/tabulator/0.8/tab.html">Tabulator</a>).</li> </ol>

It's how we use the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> as a <a href="http://dbpedia.org/resource/federated_database_system">Distributed Database</a> where (as <a href="http://www.cs.umd.edu/~hendler/2003/foaf.rdf#jhendler">Jim Hendler</a> once stated with immense clarity): I can point to records (<a href="http://dbpedia.org/resource/Entity">entity</a> instances) in your database (aka Data <a href="http://en.wikipedia.org/wiki/Data_Spaces">Space</a>) from mine. Which is to say that if we can all point to data entities/objects (not just data entities of type "Document") using these Location, Value, and Structure independent Object Identifiers (courtesy of HTTP) we end up with a much more powerful Web, and one that is closer to the "Federated and Open" nature of the Web.</p> <p>As I stated in a prior post, if you or your platform of choice aren't producing de-referencable URIs for your data objects, you may be Semantic (this data model predates the Web), but there is no "<a href="http://dbpedia.org/resource/World_Wide_Web">World Wide Web</a>" in what you are doing.</p> <h2>What are the Benefits of the Semantic Web?</h2> <ul> <strong>Consumer</strong> - "Discovery of relevant things" and be being "Discovered by relevant things" (people, places, events, and other things)</ul> <ul> <strong>Enterprise</strong> - ditto plus the addition of enterprise domain specific things such as market opportunities, product portfolios, human resources, partners, customers, competitors, co-opetitors, acquisition targets, new regulation etc..)</ul> <h2>Simple demo:</h2> <blockquote> <p>I am a <a href="http://myopenlink.net/dataspace/person/kidehen#this">Kingsley Idehen</a>, a Person who authors <a href="http://www.openlinksw.com/blog/~kidehen">this weblog</a>. I also share bookmarks gathered over the years across an array of subjects via <a href="http://myopenlink.net/dataspace/kidehen/bookmark/KingsleyBookmarks">my bookmark data space</a>. I also subscribe to a number of RSS/Atom/<a href="http://dbpedia.org/resource/Resource_Description_Framework">RDF</a> feeds, which I share via my feeds subscription data space. Of course, all of these data sources have Tags which are collectively exposed via my <a href="http://myopenlink.net/dataspace/kidehen/weblog/MyBlogDataSpace/tagcloud">weblog tag-cloud</a>, feeds subscriptions <a href="http://dbpedia.org/resource/Tag">tag</a>-cloud, and <a href="http://myopenlink.net/dataspace/kidehen/bookmark/KingsleyBookmarks/tagcloud">bookmarks tag-cloud</a> data spaces.</p> <p>As I don't like repeating myself, and I hate wasting my time or the time of others, I simply share <a href="http://myopenlink.net/dataspace/kidehen">my Data Space</a> (a collection of all of my purpose specific data spaces) via the Web so that others (friends, family, employees, partners, customers, project collaborators, competitors, co-opetitors etc.) can can intentionally or serendipitously discover relevant data en route to creating new <a href="http://dbpedia.org/resource/Information">information</a> (perspectives) that is hopefully exposed others via the Web.</p> </blockquote> <p>Bottom-line, the Semantic Web is about adding the missing "Open Data Access & Connectivity" feature to the current Document Web (we have to beyond regex, grep, xpath, xquery, <a href="http://dbpedia.org/resource/Full_text_search">full text search</a>, and other literal scrapping approaches). The Linked Data Web of de-referencable data object URIs is the critical foundation layer that makes this feasible.</p> <p> Remember, It's not about "Applications" it's about Data and actually freeing Data from the "tyranny of Applications". Unfortunately, application inadvertently always create silos (esp. on the Web) since entity data modeling, open data access, and other database technology realm matters, remain of secondary interest to many application developers.</p> <p>Final comment, RDF facilitates Linked Data on the Web, but all RDF isn't endowed with de-referencable URIs (a major source of confusion and misunderstanding). Thus, you can have RDF Data Source Providers that simply project RDF data silos via Web Services APIs if RDF output emanating from a Web Service doesn't provide out-bound pathways to other data via de-referencable URIs. Of course the same also applies to Widgets that present you with all the things they've discovered without exposing de-referencable URIs for each item.</p> <p>BTW - my final comments above aren't in anyway incongruent with devising successful business models for the Web. As you may or may not know, OpenLink is not only a major platform provider for the Semantic Web (expressed in our UDA, Virtuoso, <a href="http://dbpedia.org/resource/OpenLink_Data_Spaces">OpenLink Data Spaces</a>, and OAT products), we are also actively seeding Semantic Web (tribe: Linked Data of course) startups. For instance, Ztigist, which now has <a href="http://community.linkeddata.org/dataspace/person/mkbergman#this">Mike Bergman</a> as it's CEO alongside <a href="http://fgiasson.com/me/">Frederick Giasson</a> as CTO. Of course, I cannot do <a href="http://zitgist.com/about/">Zitgist</a> justice via a footnote in a blog post, so I will expand further in a separate post.</p> <h2>Additional information about this blog post:</h2> <ol> <li> I didn't spent hours looking for URIs used in my hyperlinks </li> <li> The post is best viewed via an RDF Linked Data aware user agents (<a href="http://demo.openlinksw.com/rdfbrowser">OpenLink RDF Browser</a>, Zitgist <a href="http://dataviewer.zitgist.com">Data Viewer</a>, <a href="http://www4.wiwiss.fu-berlin.de/rdf_browser">DISCO Hyperdata Browser</a>, <a href="http://dig.csail.mit.edu/2005/ajar/release/tabulator/0.8/tab.html">Tabulator</a>).</li> </ol>

Linked Data is vital to Enterprise Integration driven Agility

<p> <a href="http://www.linkedin.com/pub/0/207/489" id="link-id10914030">John Schmidt</a>, from Informatica, penned an interesting post titled: <a href="http://blogs.informatica.com/enterprise_data_management/2008/03/it_doesnt_matter_integration_d.html" id="link-idd6d76d8">IT Doesn't Matter - Integration Does</a>. </p> <p>Yes, integration is hard, but I do profoundly believe that what's been happening on the Web over the last 10 or so years also applies to the Enterprise, and by this I absolutely do not mean "Enterprise 2.0" since "2.0" and productive agility do not compute in my realm of discourse. </p> <blockquote>large collections of RSS feeds, Wikiwords, Shared Bookmarks, Discussion Forums etc.. when disconnected at the data level (i.e. hosted in pages with no access to the "data behind") simply offer information deluge and inertia (there are only so many hours for processing opaque information sources in a given day).</blockquote> <p>Enterprises fundamentally need to process information efficiently as part of a perpetual assessment of their relative competitive Strengths, Weaknesses, Opportunities, and Threats (<a href="http://dbpedia.org/resource/SWOT_analysis" id="link-id10776fe8">SWOT</a>), in existing and/or future markets. Historically, IT acquisitions have run counter intuitively to the aforementioned quest for "Ability" due to the predominance of "rip and replace" approach technology acquisition that repeatedly creates and perpetuates information silos across Application, Database, Operating System, Development Environment boundaries. The sequence of events typically occurs as follows:</p> <ol> <li> applications are acquired on a problem by problem basis</li> <li>back-end application databases are discovered once ad-hoc information views are sought by <a href="http://dbpedia.org/resource/Information_worker" id="link-id10a111c8">information workers</a> </li> <li>back-end database disparity across applications is discovered once holistic views are sought by <a href="http://dbpedia.org/resource/Knowledge_worker" id="link-id107997d8">knowledge workers</a> (typically <a href="http://dbpedia.org/resource/Domain_expert" id="link-id102ddf08">domain experts</a>).</li> </ol> <p>In the early to mid 90's (pre ubiquitous Web), operating system, programming language, operating system, and development framework independence inside the enterprise was technically achievable via ODBC (due to it's platform independence). That said, DBMS specific <a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id10889d20">ODBC</a> channels alone couldn't address the holistic requirements associated with Conceptual Views of disparate data sources, hence the need for Data Access Virtualization via <a href="http://dbpedia.org/resource/Federated_database_system" id="link-id10884490">Virtual Database</a> Engine technology.</p> <p>Just as is the case on the Web today, with the emergence of the "Linked Data" meme, enterprises now have a powerful mechanism for exploiting the Data Integration benefits associated with generating Data Objects from disparate data sources, endowed with HTTP based IDs (URIs).</p> <p>Conceptualizing access to data exposed Databases APIs, SOA based Web Services (SOAP style Web Services), Web 2.0 APIs (REST style Web Services), XML Views of <a href="http://dbpedia.org/resource/SQL" id="link-id117f8a00">SQL</a> Data (<a href="http://dbpedia.org/resource/SQL/XML" id="link-id104bb730">SQLX</a>), pure XML etc.. is problem area addressed by RDF aware middleware (<a href="http://esw.w3.org/topic/ConverterToRdf" id="link-id10a9deb8">RDFizers</a> e.g <a href="http://virtuoso.openlinksw.com/presentations/Virtuoso_Sponger_1/Virtuoso_Sponger_1.html" id="link-id10256fb0">Virtuoso Sponger</a>).</p> <img alt="Image" src="http://myopenlink.net:8890/%7Ekidehen/Public/images/URI_Data_Source_Pyra_Enterp.png" /> <p>Here are examples of what <a href="http://virtuoso.openlinksw.com/presentations/RDF_Mapping_Presentation_W3C_workshop3/RDF_Mapping_Presentation_W3C_workshop3.html" id="link-id129a6a30">SQL Rows exposed as RDF Data Objects </a>(identified using HTTP based URIs) would look like outside or behind a corporate firewall:</p> <ul> Customer - <a href="http://demo.openlinksw.com/Northwind/Customer/ALFKI#this" id="link-id1183acd8">Alfreds Futterkiste</a> </ul> <ul>Customer Contact - <a href="http://demo.openlinksw.com/Northwind/CustomerContact/ALFKI#this" id="link-id11746bb0">Maria Anders</a> </ul> <ul>Salesrep - <a href="http://demo.openlinksw.com/Northwind/Employee/NancyDavolio1#this" id="link-idff76ed8">Nancy Davolio</a> </ul> <ul>Customer Orders Numbers - <a href="http://demo.openlinksw.com/Northwind/Order/11084#this" id="link-id10ca2648">11084</a>, <a href="http://demo.openlinksw.com/Northwind/Order/11011#this" id="link-id11736160">11011</a>, <a href="http://demo.openlinksw.com/Northwind/Order/11078#this" id="link-id108156e0">11078</a>, <a href="http://demo.openlinksw.com/Northwind/Order/11088#this" id="link-id10747f30">11085</a> </ul> <p>What's Good for the Web Goose (<a href="http://kidehen.idehen.net/dataspace/person/kidehen%23this%3E" id="link-id10a33c50">Personal Data Space URIs</a>) is good for the Enterprise Gander (<a href="http://www.openlinksw.com/dataspace/organization/openlink#this" id="link-id109fbbe0">Enterprise Data Space URIs</a>).</p> <h2>Related</h2> <ul> <a href="http://blogs.informatica.com/enterprise_data_management/2008/02/data_access_a_cultural_or_tech.html" id="link-idffe8168">Data Access - A Cultural or Technical Challenge?</a> </ul>
