From the NSF grant proposal:

Ontology Module: This will have reasoning capabilities for querying FEED, a user interface for data entry, and an import tool. The ontologies will be maintained externally. The module will allow the recordings data and metadata to be used consistently in multi-species and multi-trait analyses (Use Cases 1-6; see Specific Aim 2). The design of the relational model for the ontology module will be based on existing database schemas that leverage ontology-based metadata annotation, such as BioSQL (http://biosql.org) and Chado (Mungall et al, 2007).
