Since July 2017, the Progenetix project has a registered namespace prefix at EBI’s identifiers.org.

This prefix will gradually be used to implement a REST syntax with stable endpoints for all Progenetix resources (e.g. arraymap.org, cnvar.org …), as well as to guide to our code mapping resources.

Wherever possible, data annotation in Progenetix uses {S}[B] OntologyClass objects for categorical values, with CURIEs as id values. So far, the Progenetix databases had used pubmed: for PubMed identifiers and ncit: for NCI Metathesaurus (Neoplasm) ids.

While the pgx prefix had been registered in 2017 with identifiers.org we recently changed the resolver and target mappings on the Progenetix server. This went hand-in-hand with the generation of unique & persistant identifiers for the main data items.
