The i2b2 software includes i2b2 ontologies that you can use right away. There are additional ontology trees that can substitute for, or can be added to, the standard i2b2 ontology trees. (See Appendix F – Advanced Ontologies.)

Which ontologies can I use right away ('out of the box')?

Tip Box

It is highly recommended for newcomers to begin their i2b2 journey by first setting up the Demo Ontology with the Demo CRC patient data.

Setting up i2b2 can be a complex undertaking. You can learn a lot about how it works, and get the system up and running most quickly, by first setting up your i2b2 instance with the i2b2 Demo Ontology and demo patient data. Those databases will comprise a "demo" project in your i2b2 instance.

When you have proven i2b2's deployment with the demo project, you can add a separate, new project for research. In this case you could use actual patient data in a second CRC database and an ACT Ontology in a second ONT database. Those new databases will comprise a "research" project in your i2b2 instance.

Actually, I inherited an i2b2 instance. How can I tell which ontology it's using?

Please compare the tables in your ONT database with the variations shown in Appendix D – i2b2 Ontology Tables.
