<title>Where Are All the RDF-based Semantic Web Applications?</title><link>http://www.openlinksw.com:443/blog/kidehen@openlinksw.com/blog/?id=1447</link><description>
In response to the &amp;quot;Semantic Web Technology&amp;quot; application classification scheme espoused by ReadWriteWeb (RWW), emphasized in the post titled:  Where are all the RDF-based Semantic Web Apps?, here is my attempt to clarify and reintroduce what OpenLink Software offers (today) in relation to Semantic Web technology.


From the RWW Top-Down category, which I interpret as: technologies that produce RDF from non RDF data sources. Our product portfolio is comprised of the following; Virtuoso Universal Server, OpenLink Data Spaces, OpenLink Ajax Toolkit, and OpenLink Data Explorer (which includes ubiquity commands).

Virtuoso Universal Server functionality summary:


  Generation of RDF Linked Data Views of SQL, XML, and Web Services in general 
  Deployment of RDF Linked Data 
  &amp;quot;On the Fly&amp;quot; generation of RDF Linked Data from Document Web information resources (i.e. distillation of entities from their containers e.g. Web pages) via Cartridges / Drivers
  
  SPARQL query language support 
  SPARQL extensions that bring SPARQL closer to SQL e.g Aggregates, Update, Insert, Delete
    Named Graph support (i.e. use of logical names to partition RDF data within Virtuoso&#39;s multi-model dbms engine)    
  Inference Engine (currently in use re. DBpedia via Yago and UMBEL)
  Host and exposes data from Drupal, Wordpress, MediaWiki, phpBB3 as RDF Linked Data via in-built support for PHP runtime
  
  Available as an EC2 AMI

  etc..

OpenLink Data Spaces functionality summary:

  Simple mechanism for Linked Data Web enabling yourself by giving you an HTTP based User ID (a de-referencable URI) that is linked to a FOAF based Profile page and OpenID
  Binds all your data sources (blogs, wikis, bookmarks, photos, calendar items etc. ) to your URI so can &amp;quot;Find&amp;quot; things by only remembering your URI
  Makes your profile page and personal URI the focal point of Linked Data Web presence
  Delivers Data Portability (using data access by value or data access by reference) across data silos (e.g. Web 2.0 style social networks)
  Allows you make annotations about anything in your own Data Space(s) on the Web without exposure to RDF markup
  A Briefcase feature that provides a WebDAV driven RDF Linked Data variant of functionality seen in Mac OS X Spotlight and WinFS with the addition of SPARQL compliance
  Automatically generates RDFa in its (X)HTML pages
  
  Blog, Wiki, WebDAV File Server, Shared Bookmarks, Calendar, and other applications that look and feel like Web 2.0 counterparts but emitt RDF Linked Data amongst a plethora of data exchange formats
  Available as an EC2 AMI
  etc..

OpenLink Ajax Toolkit functionality summary:

  Provides binding to SQL, RDF, XML, and Web Services via Ajax Database Connectivity Layer (you only need an ODBC, JDBC, OLE-DB, ADO.NET,  XMLA Driver, or Web Service on the backend for dynamic data access from Javascript)
  All controls are Ajax Database Connectivity bound (widgets get their data from Ajax Database Connectivity data sources)
  Bundled with Virtuoso and ODS installations.
  etc.

OpenLink Data Explorer functionality summary

  Distills entities associated with information resource style containers (e.g. Web Pages or files) as RDF Linked Data
  Exposes the RDF based Linked Data graph associated with information resources (see the Linked Data behind Web pages)
  Ubiquity commands for invoking the above
  Available as a Hosted Service or Firefox Extension

  Bundled with Virtuoso and ODS installations
  etc.

Note:
Of course you could have simply looked up OpenLink Software&#39;s FOAF based Profile page (*note the Linked Data Explorer tab*), or simply passed the FOAF profile page URL to a Linked Data aware client application such as: OpenLink Data Explorer, Zitgist Data Viewer, Marbles, and Tabulator, and obtained information. Remember, OpenLink Software is an Entity of Type: foaf:Organization, on the burgeoning Linked Data Web :-)

Remember my job is to try and interpret what you guys do to &#39;the mainstream&#39; (heck even early adopters like me find it difficult to follow!) So you have to help guys like me out, by spelling it out in plain english. Anyway, I got an interpreter in to help me with your post, and basically we came away with this question:&lt;br&gt;&lt;br&gt;1) if this technology automatically identifies entities in text (ala Calais) and injects RDF annotations, then it is top-down&lt;br&gt;&lt;br&gt;&amp;nbsp;&lt;br&gt;2) If this technology allows editors to high light entities in text and then generates RDF, then it is bottom up&lt;br&gt;&lt;br&gt;So, which is it? :-)&lt;br&gt;&amp;gt;&amp;gt;&lt;br&gt;&lt;br&gt;Our products are &quot;Top-down&quot; heavy. By this I mean, we produce RDF based Linked Data &quot;on the fly&quot; without user intervention. &lt;br&gt;&lt;br&gt;They are also &quot;Top-down&quot; heavy because our company mantra and product architecture philosophy is simply about:&lt;br&gt;Maximum incorporation of new and emerging technologies with minimum (if any) disruption to existing infrastructure.&lt;br&gt;&lt;br&gt;The Document Web (or Web of Linked Documents) is &quot;existing infrastructure&quot; in our world-view, so our products are geared toward distillation of the entities associated with Web Documents, and the projection of linkage (intra and inter) between these entities in the manner espoused by the &quot;Linked Data&quot; meme. &lt;br&gt;&lt;br&gt;I am happy to spend sometime with you on a &quot;Linked Data Web&quot; in plain english type discourse, it&#39;s clear to me that we have much work to do in this critical area.&lt;br&gt;&amp;nbsp;&lt;br&gt;
