Unique identifiers assigned to ontology developers

Every term in the anatomy or developmental stage ontology is identified by a unique identifier. Under the conventions that we have already established, the syntax of a PO identifier is PO:nnnnnnn, where nnnnnnn is a zero-padded unique integer of seven digits.

In order to ensure database integrity, identifiers are never removed. Terms that are retired(deleted) from the ontology are moved into the obsolete category. To ensure that the same identifier is not used twice, each participating group will be assigned non-overlapping ID ranges and listed on this page for documentation purposes. These ranges will automatically act as (internal) identifiers for the group that submitted the term.
