OCLC PURL Server

We use the PURL server from OCLC. It allows for simple redirects= of a purl to another URL, and "partial redirects" that allow a base portio= n of a PURL to be replaced with a different base portion, passing the remai= nder of the PURL as a parameter to a second service.

Functionality of the= PURL server

=20

The PURL server can only replace text at the beginning of the U= RL, and only a single replacement. For example:

=20
=20
http://some.purlserver.edu/collectioninfo/dir/itemID
=20
=20

can be redirected to:

=20
=20
http://someother.server.com/otherinfo/withMoreInfo/stuff/dir/itemID
=20
=20

This restriction makes the server very fast, but greatly restricts funct= ionality. To improve functionality, all PURLs for objects in the central re= pository are directed to our custom = Purl Resolver.

=20

Modifying PURLs (or not)=20

One drawback of this server is that it is very difficult to delete or mo= dify entries (e.g., to correct typos). People have considered hacking the d= atabase to do this, but we do not know whether anyone has been successful. = We've never considered the benefits to be worth the anticipated effort. Det= ails:
