Revision 31412, 3.2 KB (checked in by ak19, 3 years ago)

After the recent changes to implement the OAI deletion policy, no longer need to have the fake [oai] classifier and subentries written to index.db. These are no longer consulted, and the new oai-inf.db (in etc) is now consulted instead to obtain oai data.
