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

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

Linking Workflow Scenarios 1) 2) New Deposits New Deposit Existing Resource Doc. Data Doc. Data 3) 4) New Deposit Existing Resource Existing Resources Data Doc. Doc. Data

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

SHARE https://osf.io/share/

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

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

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

SHARE Ex. – Repository View

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
