2. Project Motivations
Many interrelationships exist between research resources managed in separate systems
articles
data
software
services
How can repositories establish connections between related resources?

4. Project Goal
Develop a cross-linking approach between repositories that allows links between related resources to be exchanged and made visible across systems.

7. Development Requirements
A notification service to send information about related resources between repositories
A data model for metadata exchange
Updated deposit interfaces & workflows that allow declaration of cross-repository relationships
Updated web sites that show the cross-repository relationships

8. SHARE

9. SHARE Notify Central registry of research release “events”
Events provided via a metadata feed
Multiple ways to be a feed provider
Push API
OAI-PMH harvester
Multiple ways to access the feed
Web-based GUI
Atom feed
Search service

10. Workflow Example
Scenario #2:
New document (TechNote),
existing data

11. SHARE Ex. – Notification Feed
SHARE feed excerpt
OpenSky metadata excerpt

12. SHARE Ex. – Repository View

13. Conclusion
Intended outcome – simple and scalable approach to sending relationship notifications
Adding new partners to this approach should not be difficult
Open challenges
Finding/identifying relationships
Standardizing the relationship metadata in SHARE feeds
Building web of participating resource providers
