An Item is Data of a Data Type specified by MMM-TEC or other MPAI Technical Specifications including:

  1. Identifier, i.e., the unique ID identifying the Item.
  2. Data, i.e., the actual Data of the Item.
  3. Qualifier of the Item’s Data i.e., signaling the relevant characteristics or technologies of the Item’s Data.
  4. Capabilities if the Item including rights holding Processes and their Rights, and Metadata describing specific characteristics of the Data.

An Item can be made available to an M-Instance by a Process that is directly driven by a human or Autonomous, e.g.:

  1. By sensing Media from the Universe and producing Data, Qualifier, and Rights.
  2. By producing the Item directly in the M-Instance.
  3. By importing an Item from another M-Instance
