 #### GO-CAM data model
 The primary unit of biological modeling in GO-CAM is a molecular activity, e.g. protein kinase activity, of a specific gene product or complex. A molecular activity is an activity carried out at the molecular level by a gene product; this is specified by a term from the GO MF ontology. GO-CAM models are thus connections of GO MF annotations enriched by providing the appropriate context in which that function occurs. All connections in a GO-CAM model, e.g. between a gene product and activity, two activities, or an activity and additional contextual information, are made using clearly defined semantic relations from the [Relations Ontology](https://obofoundry.org/ontology/ro.html){:target="blank"}. A more complete dscription of GO-CAM can be found in [Thomas & al 2019](https://www.ncbi.nlm.nih.gov/pubmed/31548717){:target="blank"}.
