S3B architecture meeting

S3b components:

1. SSCF
2. NLQ
3. MBB
4. Rec
5. SQE
6. TTM

We can divide those modules according to the way they access rdf storage:

• Through FOAFREALM only - SSCF
• Direct RDFDB access - NLQ, MBB, TTM
• Direct RDFDB and access to other system's (FR, JeromeDL) data - Rec, SQE (uses JDL code).

Our goals

• provide common way to access indexing service.
• provide common way to access RDFDB, that would allow to change/modify the rdf storage if needed.
• have similar interface for accessing s3b services from the other applications

Plan

Agreed plan, task that would allow us to reach the goals:

1. Investigate the solutions for unified/abstract RDFDB acceess
   • Is there something better than RDF2go
   • What is the development status of RDF2Go
2. Investigate RDFDB systems:
   • Can we switch to Mulgara/Jena/Sesame?
   • Check what query language Mulgara supports, how it differs from standard SPARQL?
3. make the SQE code independent from JDL

1. and 2. are assigned to Łukasz (as FOAFRealm developer). It is because in FR we have currently a "semi-RDF2Go" solution implemented. However, it is still imposible to change the RDFDB without an effort. Solution agreed and implemented in FOAFRealm may be deployed for other S3B components.

3. is assigned to Jakub (with a Łukasz Porwoł help, if needed)
