Identify
This verb is utilized to retrieve information about the reposi-
tory. Sending an identify request to an OAI-PMH server will
return information relating to the repository’s name, the reposi-
tory administrator’s e-mail address, the base URL of the reposi-
tory, the version of OAI-PMH supported, the time stamp of the
first record placed into the repository, how it handles deleted
records, and the harvesting granularity supported by the server.
In regard to the harvesting granularity, this doesn’t refer to the
metadata schemas supported by the OAI-PMH server, but
rather to the granularity relating to an item’s time stamp within
the repository. Granularity for harvesting can be set to any valid
IS08601 combination. Most commonly, digital repositories
use a day as the level of harvesting granularity, meaning that
requests would come in YYYY-MM-DD format, but could be
extended to allow the specification of hours, minutes, seconds,
and so on. An example of an Identify request on the Ohio State
University Libraries’ institutional repository server would look
like: http://kb.osu.edu/oai/request?verb=Identify, and it would
return the following request:
