Goals
- Encourage the broad use of DeepPhe tools and models, while maintaining openness and attribution.
- Comply with resource sharing plan as submitted to NIH. See, for example [ITCR policies](http://itcr.nci.nih.gov/about-itcr)
Distinction
We are reading "software" as referring to executable components, while "models" refers to the OWL data models developed for representation of cancer phenotypes.
