Meta Data

 

Metadata describes the data. For the Architectural Framework the availability of a metadata description is almost more important than the availability of the data, because it can describe such things as

• Rules, eg
  • validation
    • syntactic
    • semantic
  • ownership
    • access
      • aggregated
      • individual
    • update
      • create
      • update
      • approval
      • delete
• Relationships
• Relevance
• Accuracy
• Status, eg archived, private, unverified

This metadata information can be accessed to ascertain proactively the availability of information.

The New Zealand Government Locator Service (NZGLS) provides a standard based on the Australian Government Locator Service which in turn is based on the Dublin Core Metadata Initiative.

The Federated Metadata Standards? project addresses this.
