Putting the Pieces Together Grace Agnew Slide Rights Metadata Manages Permissions and constraints on permissions for Access and Use of Digital Objects. Developed and managed by Rightsholders. XrML - eXtensible Rights Management Language ODRL - Open Digital Rights Language MPEG-7 UsageInformation DS

Putting the Pieces Together Grace Agnew Slide Rights Metadata: Explicit support for SMPTE Timecodes in ODRL or XrML to enable granular constraints at the timecode level for footage licensing, etc. Smart Transport: SOAP (Simple Object Access Protocol) OpenURL Open Video Bucket Architecture

Putting the Pieces Together Grace Agnew Slide Metadata and Digital Object Administration Persistent Objects: Manage objects through changes to: hardware, software, players, search&retrieval systems, etc. Persistent Metadata: Manage metadata through schema and data element versioning changes, new metadata formats, I&R changes, hardware & database migrations.

Putting the Pieces Together Grace Agnew Slide Next Steps: Dublin Core Application Profile review, test, submit to DCMI Establish Schema Registry in XML/RDF Migrate database to Open Source Develop MPEG-7 Map; extend DC in XML to include qualified Dublin Core Implement OAI for mining of archive collections
