Information definition identification




An information definition shall have:
  • a title by which it is known;
  • an edition; and
  • a reference date for use in citing the information definition.


This requirement supports the identification and citation of an information definition.




Example: “Aerodrome Mapping Exchange Model (AMXM), 2.0.0, 2015-08-24” [RD 12].

Example: Identification information contained in a service description.

Level of Implementation



The ability to provide an exact citation, a standardised reference to the information definition, is very basic. It is hard to envisage interoperability being supported without it.

Examples of where information definitions can be cited are:

  • service descriptions
  • SWIM registries
  • academic papers

The specification caters for the fact that information definitions are often contained in service descriptions.  The identification information can, in effect, be assumed to be the same as for the service being described in a service description. This will avoid unnecessary duplication.

Verification Support


Check that:

[  ] The information definition has a title.

[  ] The information definition has an edition.

[  ] The information definition has a reference date.


The example below shows how the identification information can be embedded into an XML schema. It makes use the annotation element within the XML schema definition language.

The current examples mirror the structure of the specification on purpose without implying that this would be a real-world implementation example.
