Metadata Profile

1. Perform Joint Application Development sessions with publishers/end users

2. Develop metadata profile based on requirements gathered in JAD sessions

The core metadata profile for 3map was previously defined to have the following elements, derived from the Mandatory set of OGC metadata elements:

        6. originator
        7. pointOfContact
        8. principalInvestigator
        9. processor
        10. publisher

Extensions to the core profile

We have determined that it will be necessary to extend the core profile to include legal constraint information as defined in annnex B.2.3 of the OGC Metadata specification, lines 69-72:

    • accessConstraints [choose one]
      • 001. copyright
      • 002. patent
      • 003. patent pending

      • 005. license
      • 006. intellectualPropertyRights
      • 007. restricted
      • 008. otherRestrictions
