The document discusses two related projects regarding the use of taxonomy in the Gene Ontology (GO): 1. Eliminating references to taxon from GO term names and definitions. There is consensus that this is desirable, and the remaining terms need to be updated. 2. Determining how or if GO should associate terms with taxonomic groups. Two positions are presented: either eliminate all taxon associations, or formalize the associations in terms like "relevant_for" and use them for subsets/slims and annotation. Key open questions include how to handle taxon information currently in definitions, the purpose and risks of subsets/slims, and ensuring consistent treatment of taxonomy across OBO ontologies.
