No. Several i2b2 ontologies have been developed and are openly available for us. Any organization may also modify an existing ontology for it's own use, or develop a new ontology. (See Ontologies 201)
What ontologies can I use right away ('out of the box')?
The i2b2 database loading modules come with at least 3 sets of "metadata" or ontology trees. These are the demo ontology, the ACT ontology, and the ACT-on-OMOP ontology.
That may be the "demo" ontology, but it doesn't resemble the "ACT" ontology that our PI was showing us. How many different ontology trees does i2b2 have?

| Name | Description | Included Domains | Target Data Model |
|---|---|---|---|
| i2b2 demo ontology | default metadata from i2b2 authors | fixme | i2b2 Common Data Model (star-schema); default CRC database has matching concepts |
| ACT ontology | ENACT project | fixme | i2b2 Common Data Model (star-schema); ACT CRC demo database has matching concepts |
| ACT-on-OMOP ontology | ENACT project | fixme | i2b2 Common Data Model (star-schema), but modified with views into the OMOP Common Data Model; CRC database loaded with SYNPUF demo data has matching concepts |
How about a thumbnail description of these ontologies? How do they differ from each other?
