h2. Model Inception
 
The starting point for the LexGrid Data Model was the [Object Management Group|http://www.omg.org/] (OMG) Terminology Query Services specification, with some revisions and many simplifications. The OMG model used can be found here:

[Lexicon Query Service Specification from OMG|http://www.omg.org/cgi-bin/doc?formal/2000-06-31] - a PDF file of the model

[Lexicon Query Service Specification IDL from OMG|http://www.omg.org/cgi-bin/doc?formal/2000-06-34] - the IDL of the model

[Common Terminology Services version 1|VKC:Common Terminology Services] was also a basis upon which LexGrid was built.

The following files are historical. The current model and its revisions are found above. The first schema can be downloaded:

[LexGrid version 1.0.zip|http://www.lexgrid.org/LexGrid/downloads/LexGrid%20Model/previous%20versions/LexGrid%20version%201.0.zip] (contains both UML and XML Schema)
