PADRL Presentation 2001-11-03

  1. 1. The KMR Group at CID <ul><li>Knowledge Management Research Group </li></ul><ul><ul><ul><li>Ambjörn Naeve </li></ul></ul></ul><ul><ul><ul><li>Mikael Nilsson </li></ul></ul></ul><ul><ul><ul><li>Matthias Palm₫r </li></ul></ul></ul><ul><ul><ul><li>Fredrik Paulsson </li></ul></ul></ul><ul><ul><ul><li>Claus Knudsen </li></ul></ul></ul><ul><li>Participation in PADLR (Personalized Access to Distributed Learning Resources) </li></ul><ul><ul><li>Edutella (Infrastructure) </li></ul></ul><ul><ul><li>Modular Content Archives (Content design, Portfolio) </li></ul></ul><ul><ul><li>Mathematical Courselets </li></ul></ul>
  2. 2. PADLR and Edutella <ul><li>Edutella is a p2p framework for exchange of metadata </li></ul><ul><li>It builds on top of the JXTA (Sun) project </li></ul><ul><li>We want the following services (at least) </li></ul><ul><ul><li>Query </li></ul></ul><ul><ul><li>Mapping </li></ul></ul><ul><ul><li>Replication </li></ul></ul>
  3. 3. Basic infrastructure work within the KMR group <ul><li>The first step is designing and implementing the query service, so far we have: </li></ul><ul><li>Categorized queries into levels of expressibility </li></ul><ul><li>Agreed on a schema for expressing and exchanging queries (done mainly together with people in KBS). </li></ul><ul><li>Built a java-API for manipulation of queries. </li></ul><ul><li>Built a parser and serializer against this API </li></ul>
  4. 4. Basic infrastructure work within the KMR group <ul><li>We're currently working on: </li></ul><ul><li>Continuing developing and testing the schema and API </li></ul><ul><li>Writing utility functions to simplify translations to other query representations such as SQL and AmosQL </li></ul><ul><li>Methods for registration process in hubs. </li></ul><ul><li>Mapping schemas </li></ul><ul><li>Continuosly building consensus via keeping a close eye on parallell development in mailinglists and standardization movements (IMS, IEEE, W3C, ADL). (Bleeding edge) </li></ul>
  5. 5. Higher-level work within the KMR group <ul><li>Graphical query language using Unified Language Modeling (ULM) </li></ul><ul><li>Evaluation of the possibilities of Edutella for user-level tools: Conzilla filtering/Portfolios etc. </li></ul><ul><li>Portfolio integration (later presentation). </li></ul>
  6. 6. Hard tasks <ul><li>Agreeing on the query schema turned out to be a hassle (just as in W3C) but we solved it! </li></ul><ul><li>Finding common terminology between people within different fields such as database- and AI-research. </li></ul><ul><li>Query translations on the higher level queries are rather complex (hard algorithms). </li></ul><ul><li>Promoting RDF and Edutella internationally (IMS, LOM, ISO, Dublin Core, and many more). Much momentum behind XML-based solutions. </li></ul><ul><li>Promoting meta-data, RDF and Edutella locally. </li></ul>
  7. 7. Modular content archives Uppsala + KMR group <ul><li>Investigate how to do content design in the humanities. </li></ul><ul><li>Describe how portfolios should work (a paper). </li></ul><ul><li>Provide a proof of concept implementation of a portfolio system. </li></ul><ul><li>Develop methods for using portfolios in curriculum design and course activities. </li></ul>
  8. 8. Portfolio work <ul><li>We are working right now with design and supervision of the portfolio development </li></ul><ul><li>Developing an RDF-binding of the IMS content packaging </li></ul><ul><li>Developing an API for IMS CP </li></ul><ul><li>Making sure IMS Content Packaging is used for storing metadata and structure </li></ul><ul><li>Changing the backend representation and access into RDF format </li></ul><ul><li>Allowing an edutella peer to access the portfolios </li></ul>
  9. 9. Hard problems <ul><li>The RDF binding requires international agreement </li></ul><ul><li>Interpretation of CP information binding </li></ul><ul><li>Presentation of portfolios in browsers </li></ul><ul><li>ACLs, consistency, concurrency and distributed access (WebDav) </li></ul><ul><li>Defining the limits and possible uses of portfolios </li></ul>
