Discovery/Access Connection

• NCDDC uses metadata to make this connection

• NVODS lacks data discovery

• dynamic one built and incorporated it into the gateway (issue with real-time data)

• IOOS Plans

Task: Explore existing technologies capable of linking metadata-based searches to points of data and product access. This effort must address the dynamic nature of the points of data access . . . (Part II Metadata/Data Discovery Requirement 7, Milestone 1)
