I am please to announce the official release of the new Extensible
Repository Resource Locators (ERRoLs) Service for resolving OAI identifiers
in various ways. The ERRoL project page is at

This service can work with any repository registered in the "OAI Registry at
UIUC" that Tom Habing announced recently

For oai-identifiers, the Core ERRoL pattern is this:

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

Below is a example of a Core ERRoL. This resolves to a list of Extended
ERRoLs that will return the various types of metadata and content related to
that identifier.


For repositories that don't use the oai-identifier scheme, the Core ERRoL
pattern is this:

"http://purl.org/oai/" + <repositoryIdentifier> + "/" + <identifier>

For example:


The list of available repositoryIdentifiers can be found at

Please check out some of the other cool things this service can do by
reading the project page.

Comments and suggestions are welcome.
