[OAI-implementers] Resolver of OAI record Uniqe Identifier

[Young,Jeff]

Zeno,

ERRoLs will work for any type of identifier used in a registered OAI
repository. For oai-identifiers, the pattern is:

"http://errol.oclc.org/" + <oai-identifier>

For other types of identifiers, the pattern is:

"http://errol.oclc.org/" + <repository-identifier> + "/" + <item-identifier>

These URLs (generally) result in an OAI oai_dc GetRecord response. Other
types of results can be obtained by adding various extensions and
parameters.

Jeff

Zeno,

These data providers have been added to DP9 list. However I cannot connect
to http://drtc.isibang.ac.in/ (we can talk about this offline).

As discussed earlier
(http://www.openarchives.org/pipermail/oai-implementers/2003-October/thread.
html)
My solution will only work for data providers which follow oai-identifier
implementation guideline. For other data providers, you probably want to
talk with Thom Hickey and Jeff Young. Their solution work for all data
providers by assigning unique identifier for each repository, but you will
have to specify repo-id in requests.
