Fedora whats new(version 2.0)

• FOXML (Fedora Object XML)
• Simple XML format directly expresses Fedora
  object model
• Easily adapts to Fedora new and planned features
• Easily translated to other well-known formats
• Enhanced Ingest/Export of objects
• FOXML, METS (Fedora extension)
• Extensible to accommodate new XML formats
• Planned METS 1.4, MPEG21 DIDL

7
Fedora 2.0 (continued)

• Object-to-object Relationships
• Ontology of common relationships (RDF schema)
• Relationships stored in special datastream
  (RELS-EXT)
• Resource Index (RI)
• RDF-based index of repository (Kowari
  triple-store)
• Graph-based index includes
• Object properties and Dublin Core
• Object Relationships
• Object Disseminations
• RI Search (Search the repository as a graph)
• Powerful querying of graph of inter-related
  objects
• REST-based query interface (using RDQL or ITQL)
• Results in different formats (triples, tuples,
  sparql)

Authorization Example Policies

• Repository Policy
• Deny access to all API-M methods if not
  administrator
• Deny access to the deleteDatastream method if not
  author
• Specific Object Policy
• Deny access to object uva100 if user is not
  Thorny.
• Group Object Policy
• Deny access to the getFullArticle dissemination
  of objects whose content model is
  journal-article if not faculty
• Deny access to the secret datastream if user is
  guest

12
Authorization Example Policies

• Time-oriented Policy
• Permit students access to answers datastream of
  learning object cs125 after May 15, 2005
• Deny all access learning object cs125 after June
  15, 2005
• Backend Service Security Policy
• Deny callback by external service represented by
  Bmech10

You asked

• We wish for a out-of-box end-user client for
  Fedora.
• Cant you put the DSpace interface on top of a
  Fedora repository?
• We need something to show people Fedora right
  away (before we get for development
  resources).
• We love Fedora. It would be really great if you
  distributed a default end-user client.

18
The Answer FedoraWebIR Client

• Web-based client for institutional repository
• Configurable
• End-user submission
• Object creation template for content models
• Basic Workflow
• Search/Browse
• Easy configuration of access policy
• Development to begin this summer.

19
More Dev-Team Priorities

• Federated Repositories
• Federation with other repositories (DSpace,
  aDORE)
• note the Cornell/LANL NSF Pathways project.
• Fedora Showcase and News (on new website)
• Content Model Specification Language
• Advanced Object Creation Workbenches
• Tools for RDF browse and graph traversal
• Performance Tune millions of objects
• Web services security and Shibboleth
• Code Refactoring
• Fedora as web app (.war)
• MVC2 pattern for REST-based web exposures
• Other misc.
