This paper describes the development and definition of ODA document application profiles. Initial implementations of ODA have not, in the main, covered every aspect of the standard: rather, particular applications, such as interworking between existing equipment, have demanded the definition of particular subsets of the base standard, tailored to specific uses. The ODA standard provides for the definition of such subsets as document application profiles. A key concept in the definition of document application profiles is the “metaclass” or “constituent constraint” by which generalised ODA mechanisms are grouped for the purpose of representing conventional document features such as footnotes. A specialised notation is required for the precise definition of constituent constraints, which is provided by a proposed Addendum to the base standard. Particular document application profiles have been developed to support different levels of functionality and combinations of content types. These have now been developed as functional standards by regional standards bodies, and are being progressed as International Standards, thus enabling global document interchange. Practical experience, such as the document interworking demonstrations mounted by the ESPRIT PODA project, has been formative in arriving at suitable profile definitions, and in their validation.
