Library Cataloging
On the DC-General mail list there is a discussion going on about persistence identifiers for Web resources. I've always thought the OCLC PURL resolver was an elegant solution and wondered why it was not more widely used. There also exists CNRI's handle system and the DOI. DOI works just fine, but to join the club one needs deep pockets. That is not yet a solution for small non-profit publishers. There are also other considerations such as designing the Web site to prevent changes, avoiding names based on a current technology, and the long-term needs of the institution.Some of the resources mentioned in the discussion include:
- Digital Identifiers
