Summary
The purpose of this meeting was to formulate, discuss, and prioritize the major Fedora development items for 2010, and to start identifying who can help make them happen.
It was held in the Franklin-Wilkins Building on the Waterloo Campus of Kings College, London, Feb 23-24.
Based on a poll of attendees, the agenda focused on the following major topics:
- Content Modeling Architecture
- Module Architecture
- Storage
- Interfaces
Notes and Presentations
Enhanced Content Models
Asger presented an overview of the Enhanced Content Model work, and we discussed which parts made sense to fold into the core Fedora distribution. The discussion focused primarily on the extension mechanism and schema + relationship validation.
The group agreed that the following would be good to fold into the core distribution:
- An extension mechanism for DS_COMPOSITE_MODEL, inspired by ECM's
- Use of this extension mechanism to:
- Include XSD references
- Include OWL Lite references
- The ability to validate XSD and OWL on-demand (after ingest)
- The ability to clone objects via Fedora's APIs
The following need further discussion:
- Ability to validate XSD and OWL as prereq. to "Active" state transition
- Kai indicated interest in defining DSL(s) for validation
To drive this work forward, we identified:
Lead: Asger
Contrib: Kai
Service Definition/Deployment Improvements
Ben led a discussion of some of the outstanding issues with SDefs and SDeps.
- The ability to support multiple bindings in service deployment WSDL. Action: Create a JIRA issue for this
- Support for POST/PUT/DELETE object methods (front-end)
- Support for POST/PUT/DELETE method bindings (back-end)
- Support for SOAP method bindings (back-end)
