IBM Semantic Layered Research Platform

IBM has been doing a lot of work in the Semantic Web area. Lately they have open sourced the Java based Boca, the RDF repository component of their Semantic Web Stack. Here are some of its features:

  • Named Graphs: Partitioning of data into sets of statements that can be named with a URI and later be accessed using that named graph’s URI
  • Replication: RDF from the server may be selectively cached on client machines and data can be persisted for off line access and performance enhancement
  • Security: Named graphs are secured using a role based access control system
  • Revision history: All changes to named graphs are tracked and are available via API calls
  • Notification: The client receives updates through a JMS Notification subsystem about changes to relevant triples and named graphs

At the center of a Boca system is a server capable of storing millions of RDF triples in a DB2 database.

This is just the first part of a much larger stack that IBM has been working on, being planned for open sourcing. Here is my summary of Lee Feigenbaum list in his Open Sourcing the Semantic Layer blog:

  • Boca: [the rdf store component mentioned above].
  • DDR. The Distributed Data Repository (DDR) is the binary counterpart to Boca.
  • Queso. Queso is a semantic web-application framework.
  • ODO. ODO is a family of Perl 5 libraries for parsing, manipulating, persisting, and serializing RDF data.
  • Telar. Telar is a family of Java libraries that provide services for creating applications driven by RDF. Some Telar libraries focus on the user interface, supplying bindings between RDF data and SWT widgets...
  • Salsa. Salsa is a Boca application that brings together semantic technologies and spreadsheets.
  • Taco. Taco is a framework for measuring performance of RDF stores.

This is all coming from a Merry Band of Internetters at IBM who blog enthusiastically about their work.

Comments:

Would it be possible if in a future blog entry you could talk about semantic approaches from an industry vertical perspective and also include what standards bodies such as ACORD (www.acord.org) and others need to do in order to embrace semantic approaches. Thanks in advance.
