PoS - OAI-PMH

PoS implements the OAI-PMH. Here are some example on how to employ the engine. We are going to use the conference IHEP-LHC in the following examples.

The OAI base URL is:
 https://pos.sissa.it/oai

Each record describes a proceeding (i.e. a single contribution to a conference):
 https://pos.sissa.it/oai?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai%3Apos.sissa.it%3AIHEP-LHC%2F001

The <dc:identifier> element in the <metadata> section is in this form:
 PoS($conference-short-name)$numeral
e.g.:
 <dc:identifier>PoS(IHEP-LHC)001</dc:identifier>

Stable URLs

To obtain a stable URL of a record, one can prepend the following string to the contribution ID:
 https://pos.sissa.it/contribution?id=
e.g.:
 https://pos.sissa.it/contribution?id=PoS(IHEP-LHC)001
This will point to a landing page for the contribution.

Sets

There are two ortogonal "sets" by which each record is classified:
 https://pos.sissa.it/oai?verb=ListSets

The conference set, which represents all proceedings of a conference, such as:
 https://pos.sissa.it/oai?verb=ListRecords&metadataPrefix=oai_dc&set=conference:IHEP-LHC
The above will return all the accepted contributions of that conference.

The group set, which represent keywords, such as:
 https://pos.sissa.it/oai?verb=ListRecords&metadataPrefix=oai_dc&set=group:6
The above will return all the contributions to all conferences that have the "group:6" keyword, which is for "High Energy Physics" (please note that listing contributions by "group" may generate a lot of data).
The keywords are assigned to the conference, so each contribution of the same conference will share the same keywords.
