<p>I've finally found a second to drop a note about my keynote.</p> <p>The keynote: <a href="http://virtuoso.openlinksw.com/presentations/Creating_Deploying_Exploiting_Linked_Data2/Creating_Deploying_Exploiting_Linked_Data2.html" id="link-id103acfb8">Creating, Deploying, and Exploiting Linked Data</a>, sought to achieve the fundamental goal of: Demystify the concept of "<a href="http://dbpedia.org/resource/Linked_Data" id="link-id107134e8">Linked Data</a>" using anecdotal material that resonates with enterprise decision makers.</p> <p>To my pleasure, 90% of the audience members confirmed familiarization with the "<a href="http://dbpedia.org/resource/Data">Data</a> Source Name" concept of <a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id106d97a8">Open Database Connectivity</a> (<a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id10956268">ODBC</a>). Thus, all I had to do was map "<a href="http://dbpedia.org/resource/Linked_Data" id="link-id10a55728">Linked Data</a>" to <a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id10e77210">ODBC</a>, and then unveil the fundamental add-ons that "<a href="http://dbpedia.org/resource/Linked_Data" id="link-id10d1d290">Linked Data</a>" delivers:</p> <ul> <li>The ability to give database records names (Identifiers)</li> <li>The use of HTTP in the database record naming mechanism - which expands a named database record's reference scope via the expanse of the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> (i.e HTTP based Identifiers called URIs).</li> </ul> <p>I believe a majority of attendees came to realize that the combination above injects a new Web interaction dynamic: access to "<a href="http://dbpedia.org/resource/Topic" id="link-id110978d0">Subject matter Concepts</a>" and <a href="http://dbpedia.org/resource/Named_entity_recognition" id="link-id10ea5160">Named Entities</a> contained within a page via HTTP base Data Source Names (URIs).</p> <p>BTW - My presentation is a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id109e5e30">Linked Data Space</a> in it's own right courtesy of the <a href="http://bibliontology.com/" id="link-id10e76d90">Bibliographic Ontology</a> (which provides slide show modeling) and <a href="http://dbpedia.org/resource/RDFa" id="link-id10d48e40">RDFa</a> that allows me to embed annotations into my <a href="http://www.w3.org/Talks/Tools/Slidy/" id="link-id104be488">Slidy</a> based presentation :-)</p> <h3>Related</h3> <ul> <li> <a href="http://virtuoso.openlinksw.com/presentations/Creating_Deploying_Exploiting_Linked_Data2/Linked_Data_2008_keynote.ppt" id="link-id10a63640">PowerPoint</a> version of Presentation</li> <li> <a href="http://www.slideshare.net/rumito/linked-data-planet-key-note/" id="link-id103aaff8">Slideshare hosted </a>version</li> <li> <a href="http://www.authorstream.com/Presentation/rumito-72460-linked-data-planet-key-note-2008-keynote-science-technology-ppt-powerpoint/" id="link-id10b97c68">Authorstream hosted </a>version</li> <li> <a href="http://docs.google.com/Presentation?id=dc7jvc6m_1061gz888hdb" id="link-id10e01640">Google Docs hosted </a>version</li> </ul>

<p>Yikes! I've just discovered that the final part of the semanticweb.com's interview with <a href="http://www.cs.umd.edu/~hendler/2003/foaf.rdf#jhendler" id="link-id10483c28">Jim Hendler</a> and I, includes critical paragraphs that omit my example links :-( As you can imagine, this is a quite excruciating, bearing in mind that "Literals" are of marginal value in a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1418a578">Linked Data</a> world.</p> <p>Anyway, thanks to the Blogosphere, I can attempt to fix this problem myself -- via this post :-)</p> <p> <strong>Q. If you wanted to provide a bewildered but still curious novice a public example of <a href="http://dbpedia.org/resource/Linked_Data" id="link-id107e67d0">Linked Data</a> at work in their everyday life, what would it be?</strong> </p> <p> <strong><a href="http://myopenlink.net/dataspace/person/kidehen#this" id="link-id13851f80">Kingsley Idehen</a>:</strong> Any one of the following:</p> <p> <a href="http://community.linkeddata.org/dataspace/person/kidehen2" id="link-id144c84b0">My Linking Open Data community Profile Page</a> - the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10339910">Linked Data</a> integration is exposed via the "Explore <a href="http://dbpedia.org/resource/Data">Data</a>" Tab <a href="http://demo.openlinksw.com/rdfbrowser2/?uri%5B%5D=http%3A%2F%2Fmyopenlink.net%2Fdataspace%2Fkidehen&" id="link-id12116d10">My Linked Data Space</a> - viewed via OpenLink's AJAR (Asynchronous Javascript and RDF) based <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10728ed0">Linked Data</a> Brower <a href="http://demo.openlinksw.com/rdfbrowser2/?uri=http%3A%2F%2Fmyopenlink.net%2Fdataspace%2Fkidehen%2Fcalendar%2FKingsley%2527s%2520Calendar" id="link-id144ef138">My Events Calendar Tag Cloud</a> - a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id0xb8fdf10">Linked Data</a> view of my Calendar Space using an RDF-aware browser In all cases, you have the ability to explore my data spaces by simply clicking on the links, which on the surface appear to be standard hypertext links, although in reality you are dealing with <a href="http://dbpedia.org/resource/Linked_Data" id="link-id142827a8">hyperdata</a> links (i.e., links to entities that result in the generation of <a href="http://dbpedia.org/resource/Entity" id="link-id144c8438">entity</a> description pages that expose <a href="http://dbpedia.org/resource/Entity" id="link-id149c9cf8">entity</a> properties via <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10551628">hyperdata</a> links). Thus, you have a single page that describes me in a very rich way since it encompasses all data associated with me, covering: personal profile, <a href="http://dbpedia.org/resource/Blog" id="link-id10ac5148">blog</a> posts, bookmarks, <a href="http://dbpedia.org/resource/Tag" id="link-id122ff4b0">tag</a> clouds, social networks etc.</p> <p> <strong>Q.

This particular link exposes a typical enterprise <a href="http://en.wikipedia.org/wiki/Data_Spaces" id="link-id14202348">data space</a> (orders, customers, employees, suppliers ...) in a single page. The <a href="http://dbpedia.org/resource/Linked_Data" id="link-id144e9070">hyperdata</a> links represent intricate data relationships common to most business systems that will ultimately seek to repurpose existing legacy data sources and SOA services as <a href="http://dbpedia.org/resource/Linked_Data">Linked Data</a>. Alternatively, I would show the same links via the <a href="http://dataviewer.zitgist.com/?uri=http%3A//demo.openlinksw.com/Northwind/Customer/ALFKI" id="link-id10e2e1d0">Zitgist Data Viewer</a> (another Linked Data-aware browser). In both cases, I am exploiting direct access to entities via HTTP due to the protocols incorporation into the Data Source Naming scheme.</p>

<p>Unfortunately a number of Linking Open <a href="http://dbpedia.org/resource/Data">Data</a> (<a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-idffe3680">LOD</a>) community / <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1017b420">Linked Data</a> tribe members (myself included) aren't at the <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id10035c28">Semantic Web</a> Technologies conference in San Jose (we are in a busy period for <a href="http://idehen.net/dataspace/kidehen/calendar/MyCalendar" id="link-id10228c50">Semantic Web Technology related Conferences</a>). But all isn't lost as <a href="http://www.w3.org/People/Ivan/" id="link-id100be140">Ivan Herman</a> (W3C <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id10181b78">Semantic Web</a> Activity Lead) , <a href="http://community.linkeddata.org/dataspace/organization/lod#this" id="link-id1004a7e8">LOD</a> member, and SWEO colleague has carried the banner with aplomb.</p> <p>Ivan's presentation titled: <a href="http://www.w3.org/2008/Talks/0518-SanJose-IH/HTML/Overview.html" id="link-id11011990">State of the Semantic Web</a>, is a must view for those who need a quick update on where things are re. the <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id101797b0">Semantic Web</a> in general.</p> <p>I also liked the fact that in proper "Lead by example" manner, his presentation isn't PDF or PPT based, it's a <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> Document :-)</p> <p>Hint: as per usual, this post contains a <a href="http://dbpedia.org/resource/Linked_Data" id="link-id100bdc28">Linked Data</a> demo nugget. This time around, it's in the form of a shared calendar covering a large number of <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id1002dd00">Semantic Web</a> Technology events. All I had to do was subscribe to a number of WebDAV accessible iCal files from my <a href="http://idehen.net/dataspace/kidehen/calendar/MyCalendar" id="link-id10f90900">Calendar Data Space</a> and the platform did the rest i.e. produce <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10044188">Linked Data</a> Objects for events associated with a plethora of conferences.</p> <p>If you assimilate Ivan's presentation properly, you will note I've just generated, and shared, a large number of URIs covering a range of conference events. Thus, you can extend my contributions (thereby enriching the <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id1018ea80">GGG</a>) by simply associating additional data from your <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10180538">Linked</a> <a href="http://en.wikipedia.org/wiki/Data_Spaces" id="link-id10103330">Data Space</a> with mine. All you have to do is use my calendar data objects URIs in your statements.</p>

<p>Courtesy of <a href="http://novaspivack.typepad.com/about.html" id="link-id101d8750">Nova Spivack</a>'s post titled: <a href="http://feeds.feedburner.com/~r/typepad/MindingThePlanet/~3/295624567/tagging-and-the.html" id="link-id11067248">Tagging and the Semantic Web: Tags as Objects</a>, I stumbled across a related post by <a href="http://www.designmills.com/" id="link-idffb9a38">John Clarke</a> titled: <a href="http://feeds.feedburner.com/~r/DesignMills/~3/294554634/" id="link-id101d6138">Tagging and the Semantic Web</a>. Both of these posts use the common practice of tagging to shed light on the increasing realization that "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id11011f98"><a href="http://www.openlinksw.com/dataspace/kidehen@openlinksw.com/weblog/kidehen@openlinksw.com%27s%20BLOG%20%5B127%5D/1356" id="link-id1003f248">The Pursuit of Context</a></a>" is the fusion point between the current <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> and its evolution into a structured Web of <a href="http://dbpedia.org/resource/Linked_Data" id="link-id101d6788">Linked Data</a>.</p> <h3>How Semantic Tagging Works (from a 1000 feet)</h3> <p>When tagging a document, the semantic tagging service passes the content of a target document through a processing pipeline (a distillation process of sorts) that results in automagic extraction of the following:</p> <ul> -- <a href="http://dbpedia.org/resource/Named_entity_recognition" id="link-id1015fdd0">Named Entities</a> </ul> <ul>-- <a href="http://dbpedia.org/resource/Topic" id="link-id100ccff8">Subject matter Entities</a> (<a href="http://dbpedia.org/resource/Topic" id="link-idfe9a898">Subject matter Concepts</a> reflecting topics covered by the document</ul> <p>Once the extraction phase is completed, a user is presented with a list of "suggested tags" using a variety of user interaction techniques. The literal values of elected Tags are then associated with one or more <a href="http://dbpedia.org/resource/Tag" id="link-idfed5eb0">Tag</a> and <a href="http://dbpedia.org/resource/Tag" id="link-id101ae0c8">Tag</a> Meaning <a href="http://dbpedia.org/resource/Data">Data</a> Objects, with each Object type endowed with a unique Identifier.</p> <h3>Issues to Note</h3> <p>Broad acceptance that: "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id100b9010">Context</a> is king", is gradually taking shape. That said, "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id101d2670">Context</a>" landlocked within Literal values offers little over what we have right now (e.g. at <a href="http://del.icio.us" id="link-id1004be08">Del.icio.us</a> or <a href="http://www.technorati.com" id="link-id100421c8">Technorati</a>), long term. By this I mean: if the end product of semantically enhanced tagging leaves us with: Literal <a href="http://dbpedia.org/resource/Tag" id="link-id101e5730">Tag</a> values only, Tags associated with <a href="http://dbpedia.org/resource/Tag" id="link-id1004a890">Tag</a> Data Objects endowed with platform specific Identifiers, or <a href="http://dbpedia.org/resource/Tag" id="link-id100364f8">Tag</a> Data Objects with any other Identity scheme that excludes <a href="http://dbpedia.org/resource/Hypertext_Transfer_Protocol" id="link-id101e6630">HTTP</a>, the ability of Web users to discern or derive multiple perspectives from the base <a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id10180868">Context</a> (exposed by semantically enhanced Tags) will be lost, or severely impeded at best.</p> <p>The shape, form, and quality of the lookup substrate that underlies semantic tagging services, ultimately affects "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id10160f28">context</a> fidelity" matters such as <a href="http://dbpedia.org/resource/Entity" id="link-id100f2618">Entity</a> Disambiguation. The importance of quality lookup infrastructure on the burgeoning <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id10044b10">Linked Data Web</a> is the reason why <a href="http://www.openlinksw.com/dataspace/organization/openlink#this" id="link-id10102360">OpenLink Software</a> is intimately involved with the <a href="http://dbpedia.org/resource/DBpedia" id="link-id110760f8">DBpedia</a> and <a href="http://umbel.org/about/" id="link-id1015fc68">UMBEL</a> projects. </p> <h3>Conclusions</h3> <p>I am immensely happy to see that the Web 2.0 and <a href="http://dbpedia.org/resource/Semantic_Web" id="link-idffb8ca8">Semantic Web</a> communities are beginning to coalesce around the issue of "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id101656b0">Context</a>". This was the case at the <a href="http://events.linkeddata.org/ldow2008/" id="link-id1017b878">WWW2008 Linked Data Workshop</a>, I am feeling a similar vibe emerging from the <a href="http://www.semantic-conference.com/" id="link-idffb9978">Semantic Web Technologies</a> conference currently nearing completion in San Jose.

<p> <a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id100eb550">ODBC</a> delivers open <a href="http://dbpedia.org/resource/Data" id="link-idffd2338">data</a> access (by reference) to a broad range of enterprise databases via a '<a href="http://dbpedia.org/resource/C_(programming_language)" id="link-id104fd1d8">C</a>' based API. Thanks to the <a href="http://www.iodbc.org" id="link-id104721b0">iODBC</a> and <a href="http://www.unixodbc.org" id="link-id10954990">unixODBC</a> projects, <a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id10494670">ODBC</a> is available across broad range of platforms beyond Windows.</p> <p> <a href="http://dbpedia.org/resource/Open_Database_Connectivity" id="link-id0xc900928">ODBC</a> identifies <a href="http://dbpedia.org/resource/Data" id="link-id10f82200">data</a> sources using <a href="http://dbpedia.org/resource/Data" id="link-id0xcaad080">Data</a> Source Names (DSNs). </p> <p> WODBC (<a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> Open Database Connectivity) delivers open <a href="http://dbpedia.org/resource/Data">data</a> access to Web Databases / Data Spaces. The Data Source Naming scheme: <a href="http://dbpedia.org/resource/Uniform_Resource_Identifier" id="link-id1009ce40">URI</a> or IRI, is <a href="http://dbpedia.org/resource/Hypertext_Transfer_Protocol" id="link-id101fc1b0">HTTP</a> based thereby enabling data access by reference via the Web. </p> <p><a href="http://dbpedia.org/resource/Open_Database_Connectivity">ODBC</a> DSNs bind ODBC client applications to Tables, Views, Stored Procedures. </p> <p>WODBC DSNs bind you to a Data <a href="http://en.wikipedia.org/wiki/Data_Spaces" id="link-id10182a88">Space</a> (e.g. my <a href="http://myopenlink.net/dataspace/person/kidehen" id="link-id105a7858">FOAF based Profile Page</a> where you can use the "Explore Data Tab" to look around if you are a human visitor) or a specific <a href="http://dbpedia.org/resource/Entity" id="link-id10bd8578">Entity</a> within a Data <a href="http://en.wikipedia.org/wiki/Data_Spaces" id="link-id10780dc0">Space</a> (i.e <a href="http://myopenlink.net/dataspace/person/kidehen#this" id="link-id10848e08">Person Entity Me</a>).</p> <p>ODBC Drivers are built using APIs (DBMS Call Level Interfaces) provided by DBMS vendors. Thus, a DBMS vendor can chose not to release an API, or do so selectivity, for competitive advantage or market disruption purposes (it's happened!).</p> <p>WODBC Drivers are also built using APIs (Web Services associated with a Web Data <a href="http://en.wikipedia.org/wiki/Data_Spaces" id="link-id0xcbe6348">Space</a>). These drivers are also referred to as <a href="http://www.openlinksw.com/weblog/public/search.vspx?blogid=127&q=rdf%20middleware&type=text&output=html" id="link-id16564058">RDF Middleware</a> or RDFizers. The "Web" component of WODBC ensures openness, you publish Data with URIs from your <a href="http://dbpedia.org/resource/Linked_Data" id="link-id1064a768">Linked Data</a> Server and that's it; your data <a href="http://en.wikipedia.org/wiki/Data_Spaces">space</a> or specific data entities are live and accessible (by reference) over the Web!</p> <p>So we have come full circle (or cycle), the Web is becoming more of a structured database everyday! What's new is old, and what's old is new! </p> <p>Data Access is everything, without "Data" there is no <a href="http://dbpedia.org/resource/Information" id="link-id100a9de8">information</a> or <a href="http://dbpedia.org/resource/Knowledge" id="link-id10bb67e8">knowledge</a>. Without "Data" there's not notion of vitality, purpose, or value.</p> <p>URIs make or break everything in the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10a71638">Linked Data</a> <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id10494400">Web</a> just as ODBC DSNs do within the enterprise. </p> <p>I've deliberately left <a href="http://dbpedia.org/resource/Java_Database_Connectivity" id="link-id10a05280">JDBC</a>, <a href="http://dbpedia.org/resource/ADO.NET" id="link-id104e4a70">ADO</a>.<a href="http://dbpedia.org/resource/ADO.NET" id="link-id10215668">NET</a>, and OLE-DB out of this piece due to their respective programming languages and frameworks specificity. None of these mechanisms match the platform availability breadth of ODBC.</p> <p>The Web as a true <a href="http://dbpedia.org/resource/Model-view-controller" id="link-id108ee598">M</a>-<a href="http://dbpedia.org/resource/Model-view-controller" id="link-id0xcda5e90">V</a>-C pattern is now crystalizing. The "M" (Model) component of M-V-C is finally rising to the realm of broad attention courtesy of the "<a href="http://www.w3.org/DesignIssues/LinkedData.html" id="link-id1024ff08">Linked Data" meme</a> and "<a href="http://dbpedia.org/resource/Semantic_Web" id="link-id1831b418">Semantic Web</a>" vision.</p> <p>By the way, M-V-C lines up nicely with Web 1.0 (Web Forms / Pages), Web 2.0 (Web Services based APIs), and Web 3.0 (Data Web, Web of Data, or <a href="http://dbpedia.org/resource/Linked_Data" id="link-id0xb6d0e90">Linked Data</a> <a href="http://dbpedia.org/resource/Giant_Global_Graph" id="link-id0xb22a158">Web</a>) :-)</p>

<p>Unfortunately, I could only spend 4 days at the recent <a href="http://www2008.org/" id="link-id196acf60">WWW2008</a> event in <a href="http://dbpedia.org/resource/Beijing" id="link-id1974fe28">Beijing</a> (I departed the morning following the <a href="http://events.linkeddata.org/ldow2008/" id="link-id1863f858">Linked Data Workshop</a>), so I couldn't take my slot on the "Commercializing the <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id18990f90">Semantic Web</a> panel" etc.. Anyway, thanks to the <a href="http://dbpedia.org/resource/World_Wide_Web">Web</a> I can still inject my points of view in the broad Web based discourse. Well so I hoped, when I attempted to post a comment to Paul Miller's ZDNet domain hosted <a href="http://dbpedia.org/resource/Blog" id="link-id180d6750">blog</a> thread titled: <a href="http://blogs.zdnet.com/semantic-web/?p=132" id="link-id12d206c0">Commercialising the Semantic Web</a>.</p> <p>Unfortunately, the cost of completing ZDNet's unwieldy signup process simply exceeded the benefits of dropping my comments in their particular space :-( Thus, I'll settle for a trackback ping instead.</p> <p>What follows is the cut and paste of my intended comment contributions to Paul's post.</p> <p>Paul,</p> <p> As discussed earlier this week during <a href="http://blogs.talis.com/nodalities/2008/05/kingsley-idehen-talks-about-openlink-software-linked-data-and-the-semantic-web.php" id="link-id1332fb48">our podcast session</a>, commercialization of <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id17382338">Semantic Web</a> technology shouldn't be a mercurial matter at this stage in the game :-) It's all about looking at how it provides value :-)</p> <p>From the <a href="http://dbpedia.org/resource/Linked_Data" id="link-id10d4f4a8">Linked Data</a> angle, the ability to produce, dispatch, and exploit "<a href="http://dbpedia.org/resource/Context_%28language_use%29" id="link-id13bed160">Context</a>" across an array of "Perspectives" from a plethora of disparate <a href="http://dbpedia.org/resource/Data" id="link-id1731e5f0">data</a> sources on the Web and/or behind corporate firewalls, offers immense commercial value.</p> <p> <a href="http://developer.yahoo.com/searchmonkey/" id="link-id1975d248">Yahoo's Searchmonkey</a> effort will certainly bring clarity to some of the points I made during the podcast re. the role of URIs as "value consumption tickets" (<a href="http://dbpedia.org/resource/Data" id="link-id173eb7b0">Data</a> Services are exposed via URIs). There has to be a trigger (in user space) that compels Web users to seek broader, or simply varied, perspectives as a response to <a href="http://dbpedia.org/resource/Data" id="link-id0x1c7e7f60">data</a> encountered on the Web. Yahoo! is about to put this light on in a big way (imho).</p> <p>The "self annotating" nature of the Web is what ultimately drives the manifestation of the long awaited <a href="http://dbpedia.org/resource/Semantic_Web" id="link-id0xa18a83e8">Semantic Web</a>. I believe I postulated about <a href="http://www.openlinksw.com/weblog/public/search.vspx?blogid=127&q=self%20annotation&type=text&output=html" id="link-id173d7458">"Self Annotation & the Semantic Web" in a number of prior posts</a> which, by the way, should be <a href="http://www.openlinksw.com/weblog/public/search.vspx?blogid=127&type=text&kwds=self%20annotation&OpenSearch" id="link-id10b12208">DataRSS compatible right now</a> due to Yahoo's support of OpenSearch <a href="http://dbpedia.org/resource/Data">Data</a> Providers (which this <a href="http://dbpedia.org/resource/Blog" id="link-id170b8df8">Blog</a> Space has been for eons).</p> <p>Today, have many communities adding strucuture to the Web (via their respective tools of preference) without explicitly realizing what they are contributing. Every RSS/Atom feed, <a href="http://dbpedia.org/resource/Tag" id="link-id183d5178">Tag</a>, Weblog, Shared Bookmark, <a href="http://dbpedia.org/resource/WikiWord" id="link-id10c5e758">Wikiword</a>, Microformat, Microformat++ (<a href="http://dbpedia.org/resource/Embedded_RDF" id="link-id16d8ee40">eRDF</a> or <a href="http://dbpedia.org/resource/RDFa" id="link-id1059a688">RDFa</a>), <a href="http://dbpedia.org/resource/GRDDL" id="link-id1090ae10">GRDDL</a> stylesheet, and RDFizer etc.. is a piece of structured data.</p> <p>Finally, the different communities are all finding ways to work together (thank heavens!) and the results are going to be cataclysmic when it all plays out :-)</p> <p>Data, Structure, and Extraction are the keys to the Semantic Life! First you get the Data in a container (<a href="http://dbpedia.org/resource/Information" id="link-id180e5648">information</a> resource), and then you add Structure to the <a href="http://dbpedia.org/resource/Information" id="link-id103801e0">information</a> resource (RSS, Atom, <a href="http://dbpedia.org/resource/Microformats" id="link-id17825e40">microformats</a>, <a href="http://dbpedia.org/resource/RDFa" id="link-id189a8738">RDFa</a>, <a href="http://dbpedia.org/resource/Embedded_RDF" id="link-id1933d5c0">eRDF</a>, SIOC, FOAF, etc.), once you have Structure RDFization (i.e. transformation to <a href="http://dbpedia.org/resource/Linked_Data" id="link-id19744878">Linked Data</a>) is a synch thanks to <a href="http://dbpedia.org/resource/Resource_Description_Framework" id="link-id180dde30">RDF</a> Middleware (as per <a href="http://www.openlinksw.com/weblog/public/search.vspx?blogid=127&type=text&kwds=self%20annotation&OpenSearch" id="link-id16dc3130">earlier RDF middleware posts</a>).</p>
