  Semantic Definition Format (SDF) for Data and Interactions of Things
                        draft-onedm-t2trg-sdf-00

Abstract

   The Semantic Definition Format (SDF) is a format for domain experts
   to use in the creation and maintenance of data and interaction models
   in the Internet of Things.  It was created as a common language for
   use in the development of the One Data Model liaison organization
   (OneDM) definitions.  Tools convert this format to database formats
   and other serializations as needed.

   An SDF specification describes definitions of SDF Objects and their
   associated interactions (Events, Actions, Properties), as well as the
   Data types for the information exchanged in those interactions.

   A JSON format representation of SDF 1.0 is defined in this document.
