On 05/24/2001, the DSpace team hosted a discussion with W3C team members
and other members of the RDF community to discuss approaches (strategies
and specific implementation approaches and toolkits) to establishing an RDF
store for DSpace. See pre-reading
<http://lists.w3.org/Archives/Public/www-rdf-dspace/2001May/0019.html>.
An IRC Log of the discussion is available at:
<http://www.w3.org/2001/05/24-dspace-irc>
This note summarizes the outcomes and followup actions that emerged from
that dialogue.

========================================================
Summarized Outcomes
I. Eric Prud'hommeaux offered an alternative strategy not described in the
meeting's pre-reading, to split information storage between closed-world
relational tables and an RDF store. We called this approach
(1C). Approach 1C does not replicate information, but requires that
requests for information be resolved to either the RDBMS or the triple
store, as appropriate.
=> (ericp) writeup notes on RDF/RDBMS federation approach
and <mailto:www-rdf-dspace@w3c.org>
=> (pbreton, ericp) offline followup dialogue
II. Strong consensus around approach 1A (or 1C - but we deferred this to
offline exploration). Concern noted about potential issues regarding
information coherency and transactional capabilities.
III. Given strong consensus, moved to identifying potential toolkits
suitable for 1A/1C implementation on java/postgress implementation
platform. Identified five (no particular order):
1. ICS-Forth RDFSuite <http://139.91.183.30:9090/RDF/>
2. Jena <http://www-uk.hpl.hp.com/people/bwm/rdf/jena/>
3. EOR <http://eor.dublincore.org/>
4. Database-persistent SiRPAC <no URL available>
(perhaps superseded by EOR, development currently orphaned)
5. DoJo (builds on Jena) <no URL available>
=> (DSpace) offline investigation
=> (DSpace, der) dialogue re: storage APIs, requirements for
schema support
IV. Discussion of "automatic / low-cost" generation of RDF
=> (pbreton) write note on two "poles" of RDF generation
(implicit, heuristic-driven?..... explicit driven by
external schema)
and <mailto:www-rdf-dspace@w3c.org>
observation:
record what you know with certainty,
also make assertions about what you know you don't know
=> (DSpace) consider indecs event model
<http://www.indecs.org>,
<http://www.dlib.org/dlib/january99/bearman/01bearman.html>
=> (DSpace, der) dialogue on bean-oriented RDF generation
strategies (reflection)
