Introduction to HemOnc vocabulary
In late 2018, we began to work closely with the OHDSI Oncology Subgroup to transition from the existing OWL format to the widely-used OMOP format. The first phase of this work was completed in June 2019 and a portion of the HemOnc vocabulary has been released to the public through the ATHENA tool.You can see how this looks by searching for "GemOx" using this link. More details here.
Beyond what is available through ATHENA, the full ontology is freely available for academic or non-commercial use, upon request. We are also willing to discuss commercial uses on a case-by-case basis. Please let us know of your interest by sending an email ([email protected]).

Introduction to OWL ontology (historical)
In the summer of 2017, we began the process of converting portions of the HemOnc.org website content into a formal OWL ontology, along with some additional external information such as RxNorm identifiers. As of the last release (2018-10-29), the ontology contains information on:
- Diseases: names, classifications
- Interventions, in four major classes:
- Biologic products: factor replacement, cellular therapy, etc.
- Drugs: names, synonyms, classifications, RxCUI (when available), sigs
- Regimens: names, synonyms, classifications, components, references
- References: title, journal, year of publication, classifications, number of authors, authors
- Authors: name
For a much more detailed explanation, you can download the latest release notes here: File:Release notes 2018-10-29.docx.
Note: due to a shift to an OMOP-compatible database, we do not plan to support additional versions of the ontology in OWL, for the time being. See below.
