[Discussion] Stuart talked about the value of using RDF, where the structure of the data is encoded in the data itself instead of relying totally on a relational database. Ryan and Stuart's experience has been that this is very useful, and supports inferencing. There are still issues of how much of the implementation is based on RDF. Jon feels that there are intrinsic limitations on what other technologies you can use. Jon is particularly concerned with what languages can be used, particularly if we want to distribute the software. Ryan agrees that we need to pick technologies that are supported over time. Stuart points out that we didn't promise to distribute software, rather to support distributed registries that could communicate with one another. Diane points out that we do need to think about distribution, lest we be the only extant registry (an unsustainable prospect). Stuart agrees that we need to think about this as we move along.

Agenda and Notes for Telecon, Oct. 3, 2005

This conference call needs to be sharply focused on infrastructure/technology questions

1. Commitment to Resource Description Framework (RDF) and its possible implications:

[Discussion] Stuart talked about the value of using RDF, where the structure of the data is encoded in the data itself instead of relying totally on a relational database. Ryan and Stuart's experience has been that this is very useful, and supports inferencing. There are still issues of how much of the implementation is based on RDF. Jon feels that there are intrinsic limitations on what other technologies you can use. Jon is particularly concerned with what languages can be used, particularly if we want to distribute the software. Ryan agrees that we need to pick technologies that are supported over time. Stuart points out that we didn't promise to distribute software, rather to support distributed registries that could communicate with one another. Diane points out that we do need to think about distribution, lest we be the only extant registry (an unsustainable prospect). Stuart agrees that we need to think about this as we move along.

Ryan and Jon will explore the specific choices about RDF servers/data stores and query options and make a recommendation.

2. SKOS as "default" scheme generation framework

Stuart feels that SKOS is the only available choice--really not much out there. Early attempts did not work out. Using SKOS will enable us (require us) to provide some tools to assist users to generate vocabularies. Stuart believes (and Diane agrees) that SKOS exceeds the power that most vocabularies need and is extensible. Jon pointed out that Alastair says it's built on OWL and extensible in that direction. All agree that SKOS is a good starting place and will allow us to build usable interfaces.

Stuart would like to implement an editor that uses SKOS, and believes that this will fulfill most of our needs for the immediate future and leave OWL for later. We are unlikely to do full inferencing or support OWL for anything except import/export.

Jon asked about ISO11179, and Stuart quoted Rachel H.'s feeling that the ISO community was very disconnected from Semantic Web vocabulary issues. Stuart thinks that it may have some effect on describing schemas at some point. Ryan asked about application profiles and Stuart mentioned that we will talk about some of those issues at our F2F meeting.

3. Issues of Zope/Plone (or any other content management system) to handle select functionality

      • Visitor
      • Registered User
      • Organization Contact
    • SKOS (working vocabulary representation)
      • Concept Schemes
      • Concepts
