3MAP - milestone 3.

metadata : core elements

Core Metadata Elements

3map will support multiple metadata element sets, allowing users to tag data according to a schema of their choosing, appropriate to their worldview and requirements.

However, all Features created in the 3map interface will have a core set of mandatory elements, in order to support, at a minimum, initial data discovery.

Most of the elements in this mandatory set can be implied from user actions, and will not need to be directly edited by users.


Element set

Ping's core metadata elements will be the set of Mandatory elements from OGC Metadata
(ISO 19115:2003 - Metadata)

Annex B (Data dictionary for geographic metadata) contains over 400 tags. All of these could be appropriate for various applications of the 3map platform. An analysis of Annex B indicates a much smaller subset of Mandatory elements, which corresponds well to other core standards.

The diagram below shows the relationship between elements in this hierarchy.

The table below details those relationships, and defines the elements in sufficient detail for implementation.
