 Linked Data Deployment
 

 
Feature
Description
Benefit
 
 
   Automatic Deployment  
   Linked Data Pages are now automatically published for every Virtuoso Data Object; users need only load their data into the RDF Quad Store.   
   Handcrafted URL-Rewrite Rules are no longer necessary.  
 
 
   HTTP Metadata Enhancements  
   HTTP Link: header is used to transfer vital metadata (e.g., relationships between a Descriptor Resource and its Subject) from HTTP Servers to User Agents.  
   Enables HTTP-oriented tools to work with such relationships and other metadata.  
 
 
   HTML Metadata Embedding  
   HTML resource &amp;lt;head /&amp;gt; and &amp;lt;link  /&amp;gt; elements and their @rel attributes are used to transfer vital metadata  (e.g., relationships between a Descriptor Resource and its Subject) from HTTP Servers to User Agents.  
   Enables HTML-oriented tools to work with such relationships and other metadata.  
 
 
   Hammer Stack Auto-Discovery Patterns  
   HTML resource &amp;lt;head /&amp;gt; section and &amp;lt;link  /&amp;gt; elements, the HTTP Link: header, and XRD-based &amp;quot;host-meta&amp;quot; resources collectively provide structured metadata about Virtuoso hosts, associated Linked Data Spaces, and specific Data Items (Entities). 
   Enables humans and machines to easily distinguish between Descriptor Resources and their Subjects, irrespective of URI scheme.  
 



 Linked Data Middleware
 


  Feature
Description
Benefit


   New Sponger Cartridges  
   New cartridges (data access and transformation drivers) for Twitter, Facebook, Amazon, eBay, LinkedIn, and others.   
   Enable users and user agents to deal with the Sponged data spaces as though they were named graphs in a quad store, or tables in an RDBMS.  



   New Descriptor Pages  
   HTML-based descriptor pages are automatically generated.  
   Descriptor subjects, and the constellation of navigable attribute-and-value pairs that constitute their descriptive representation, are clearly identified.  


   Automatic Subject Identifier Generation  
   De-referenceable data object identifiers are automatically created.  
   Removes tedium and risk of error associated with nuance-laced manual construction of identifiers. 


    Support for OData, JSON, RDFa  
   Additional data representation and serialization formats associated with Linked Data.  
   Increases flexibility and interoperability. 




 Data Virtualization
 


  Feature
Description
Benefit


   Materialized RDF Views  
   RDF Views over ODBC/JDBC Data Sources can now (optionally) keep the Quad Store in sync with the RDBMS data source.  
   Enables high-performance Faceted Browsing while remaining sensitive to changes in the RDBMS data sources.  



   CSV-to-RDF Transformation  
   Wizard-based generation of RDF Linked Data from CSV files.  
   Speeds deployment of data which may only exist in CSV form as Linked Data.  


   Transparent Data Access Binding  
   SPASQL (SPARQL Query Language integrated into SQL) is usable over ODBC, JDBC, ADO.NET, OLEDB, or XMLA connections.  
   Enables Desktop Productivity Tools to transparently work with any blend of RDBMS and RDF data sources. 




 Dynamic Data Exchange &amp;amp; Data Replication
 


  Feature
Description
Benefit


   Quad Store to Quad Store Replication  
   High-fidelity graph-data replication between one or more database instances.  
   Enables a wide variety of deployment topologies.  



   Delta Engine  
   Automated generation of deltas at the named-graph-level, matches transactional replication offered by the Virtuoso SQL engine.  
   Brings RDF replication on par with SQL replication. 


    PubSubHubbub Support  
   Deep integration within Quad Store as an optional mechanism for shipping deltas.  
   Enables push-based data replication across a variety of topologies. 




 Security
 


  Feature
Description
Benefit


    WebID support at the DBMS core  
   Use WebID protocol for low-level ACL-based protection of database objects (RDF or Relational) and Web Services.  
   Enables application of sophisticated security and data access policies to Web Services (e.g., SPARQL endpoint) and actual DBMS objects. 



   Webfinger  
   Supports using mailto: and acct: URIs in the context of WebID and other mechanisms, when domain holders have published necessary XRDS resources.  
   Enables more intuitive identification of people and organizations. 


   Fingerpoint  
   Similar to Webfinger but does not require XRDS resources; instea,d it works directly with SPARQL endpoints exposed using auto-discovery patterns in the &amp;lt;head  /&amp;gt; section of HTML documents.  
   Enables more intuitive identification of people and organizations.

I&#39;ve launched a wiki directory that is open to any person, any business, any organization.  It&#39;s running Semantic Mediawiki, so the  juice  for search engine ranking and ASK queries is built-in.  Hoping to attract people who want to say something about themselves (or their enterprise) without worrying about some teenaged vandal messing with their page ( MARK RICHMOND SLEEPS WITH HIS PET FERRET ! ! ! LOLZ ! ! ), I&#39;ve put single-user  protection  on all pages in the Directory that are about a living person or any legal entity.  There&#39;s still community editing on the non-legal pages, though (like  water ,  Lake Michigan , or  heating oil ).  That way, everybody can get the benefit of interlinking within the wiki, plus semantic tagging.  For those too bothered by either wiki markup or semantic tags, we can create pages for a small fee.  Oh, and users are allowed to advertise, sell, promote   whatever   on their own Directory page(s).  If you&#39;re interested in adding your page to the 35,000 we have already, come visit MyWikiBiz.com.</description></item><item><title>Abu</title><guid>http://www.openlinksw.com:443/blog/vdb/blog/?id=1638#5434</guid><link>http://www.openlinksw.com:443/blog/vdb/blog/?id=1638#5434</link><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">kornchild666@web.de</dc:creator><pubDate>Tue, 23 Oct 2012 06:40:06 GMT</pubDate><description>History, I guess.

That&#39;s no longer true, and your point is valid.</description></item><item><title>Raja</title><guid>http://www.openlinksw.com:443/blog/vdb/blog/?id=1638#5296</guid><link>http://www.openlinksw.com:443/blog/vdb/blog/?id=1638#5296</link><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">gordonr@cc.umanitoba.ca</dc:creator><pubDate>Mon, 19 Mar 2012 15:04:58 GMT</pubDate><description>I&#39;ve been out of this programming lark ahttgeoler too long. I can get a faint hazy sense that SPARQL support in an RDF API for PHP would probably be a Good Thing, but ask me what it would actually enable people to do and I&#39;ll do my best goldfish impression. Perhaps I need to do some more reading.

As such, if you have just one database, which is the whole world for your application, then you absolutely don&#39;t have any kind of data merging problem. As such, the tried-and-tested SQL database solution is absolutely the most common solution, as the applications are designed with it in mind. As such, SQL probably is the right solution for a WordPress instance, or something similar.But as soon as you have more than one application needing that data store   that&#39;s when you have that data sources problem, and that&#39;s when moving to RDF will pay dividends.As the world moves away from data silos to building with the assumption that data will be remixed, repurposed, and reinterpreted, that&#39;s when we&#39;ll see RDF being embraced.&lt;br /&gt;

	Hey guys and girls of OpenLink,&lt;/p&gt;&lt;br /&gt;
&lt;p&gt;&lt;br /&gt;
	Do you have any interesting updates to Virtuoso on the SQL syntax side, or on the code hosting side? Just curious, I mean I understand that your focus is on Semantic Web, Linked Data and the Web of Data, but just curious if things are progressing on the pure database and web server side too.&lt;/p&gt;&lt;br /&gt;
&lt;p&gt;&lt;br /&gt;
	Many thanks,&lt;/p&gt;&lt;br /&gt;
&lt;p&gt;&lt;br /&gt;
	Daniel Lewis of &lt;a href=&quot;http://vanirsystems.com/&quot;&gt;Vanir Systems&lt;/a&gt;&lt;/p&gt;
