T01 Discovery
The NDG discovery portal provides a web portal accessible by standards compliant browsers that allows a user to freely discover datasets held by data providers who have offered up appropriately formatted discovery metadata for harvest by the discovery portal backend.
Where NDG compliant data providers hold datasets, the portal will provide information about NDG services available for those datasets, and provide links to instantiate these services.
The key subcomponents are (with keywords for tickets in brackets):
- Software for discovery portal deployment (available to third parties to deploy)
- Database backend (NDGdb?)
- Public Web Service Interface (code) (DiscoveryWS)
- Web based GUI interface (DiscoveryGui?)
- Deployed discovery service (running at NDG)
- Scripts to automate harvesting (DiscoveryAuto)
- OAI repository (OAI?)
- Running web services and portal GUI. (DiscoveryService?)
- Schema instances for various discovery formats
