[raw presentation notes]

Also see my notes from last year's European Fedora User Meeting.

They are tagged under EuroFedora2005.

* Intro
* Digital Objects
* Repository Service
* 15:45 Service Framework in Focus
=== Break ===
* 16:00 Semantic Web and RDF
* RDF and Fedora
* Case Study: NSDL
* Future Directions

Problem Space

* Complex, compound, dynamic objects

Theme

* From Documents to Integrated Information Networks

"a network-based scholarly communications system"

Repositories situated at intersection of key social and technical trends

Technical Context:
* SOA
* Web 2.0
* Semantic Web

Sampling of Fedora Community

* ARROW and DART - Australia
*** eSciDoc - Max Planck
* DRC - OhioLink
* Danish Technical University (DTU)
* Wegener Institute, Polar/Marine, Germany

Are there IR clients for Fedora?

** Fez http://sourceforge.net/projects/fez "DSpace plus"
* VALET http://www.valet.vtls.com/
* Elated http://elated.sourceforge.net/
* FIRE

Digital Object Model

Disseminators - metadata about things you can use [my summary] - a disseminator can tell Fedora how
to connect to a Web Service, but a disseminator is not a Web Service itself

Fedora Repository Service

* Exposes through SOAP and REST:
  - Manage (Ingest, Export, Validate, Version)
  - Access (Get)
  - Registry Search
  - Resource Index

Fedora Security Architecture

[various stuff]
* Shibboleth-to-Fedora servlet filter

XACML Policy

Preservation Support

[various stuff]
* Preservation Support Services (forthcoming 2006-2007) - being defined by working group

There are some performance limitations in triple-stores
- Fedora uses the Kowari triple-store
- NSDL is storing ~200 million triples?

Fedora and the Semantic Web

Motivation

* exposing repository as a network of objects
  - relationships
  - query the graph; discovery of related stuff
* indexing based on generalizable data model
* extensible enrichment of object descriptions
* inferencing from structure of graph

What are the applications?

* Digital libraries with structured objects
* Publishing Systems
  - Journals with Articles
* eScience
  - Text with Datasets
* Semantic networks

[There was more but I switched back to the other workshop.]
