The Cell Line Ontology (CLO) contains entries for a lot of cell lines. The NCI60 database screened a lot of drugs against 59 (originally 60) cell lines, which I like to represent in my RDF by CLO classes. For example, the NCI60 database speaks of the HL60 cell line for which the CLO contains multiple entries (e.g. HL60 Ast.3 and HL60 M2). However, I was wondering of there already is a mapping between the the database and the CLO ontology.
