Metadata Registry – Example
Content owner adds content to a repository.
XXXX XXXX XXXX
Content
Metadata for that content is generated in the Repository and pushed, via a Registration Service, into Metadata Registry, creating a digital object.
The Metadata Registry provides Information Management and Discovery Services for users.

CAP Collaborators
Interagency Technical Advisory Group (iTAG) To provide a forum for Federal agency and entity coordination on operational requirements and insights on how to maximize access to scientific and technical data. Members of the iTAG are Federal employees participating in their individual capacity as subject matter experts and providing their own perspectives from a range of agency and entity settings including:

Provide VM (pre-configured)/instructions to configure CAP instance: Interface: CAP API, tools, utilities, etc. System: Handle system, DO libraries, etc.
Adopter: Customize CAP instance with operational needs: Forms, applications, PID naming, integration with: Existing environment (PIV, user profile, etc.) Datasets: schemas, type definitions, etc. Tools: curation, analytics, visualization, etc. Others…
