gist is our minimalist upper ontology. It is designed to have the maximum coverage of typical business ontology concepts with the fewest number of primitives and the least amount of ambiguity. The ontology is free for you to use as you see fit. The most current version will always be available at http://ontologies.semanticarts.com/gist/gist.owl previous versions will remain available in the document list below.

Note: at one point we separated out the Unit of Measure ontology. If you only want Units of Measure, gistUOM2009Aug11 is still current, and we will continue to update it as needed. The most current version will always be available at
http://ontologies.semanticarts.com/gist/gistUOM.owl; previous versions will remain available in the document list below.

In the Sept 2009 and June 2009 versions of gist, the UOM is not included but is imported into it. To make gist easier to use (i.e., to avoid having to mess with the import), as of October 2009 gist includes a copy of the UOM ontology.

gist2010June10.vsd, a large (30′ by 40′) Visio diagram suitable for hanging, has all the formal definitions and the comments that describe each concept. If you have our e6tOWL Tool (described here), you can generate the owl directly from this diagram; otherwise you can use it for documentation. Here is a pdf version of the full-size diagram.

The ”placemat” is a smaller (11″ by 17″) version that has just the names of the concepts. This is useful once you know what all the concepts are and you only need to remember their names.
