MPD Catalog

A MPD Catalog is an XML document that contains basic information about the package (name, description, purpose, etc.) and a listing of the package’s key artifacts. It is a required artifact in an IEPD.

The MPD Catalog establishes identification metadata, conformance targets, purpose, general content, lineage, and other metadata. Metadata includes:

  • Uniform Resource Identifier (URI)
  • Name
  • Version number
  • The conformance target identifier
  • A copy of all schema documents needed to validate any instance document class it defines
  • (Optional) Alternate representations in addition to XML Schema (e.g., generic diagram, UML/XMI, database format, spreadsheet, etc.)
  • (Optional) Miscellaneous other documentation or file artifacts for assisting with usage or implementation

Conformance

The MPD Specification defines a MPD Catalog as a conformance target, with a set of rules that must be followed in order to be considered conformant.

The first step is to make sure that the catalog file validates against its MPD Catalog XML Schema.

See the following sections from the MPD Specification for more information about the catalog file:
