Kia ora Tim,

The first webform example that comes to mind as similar to what you want is at http://wiki.canterbury.ac.nz/display/LIBRARY/Articles+without+DOIs

As written the function convert(form) has some extra stuff around DOIs and EBL (.eblib.com) which you can strip out.
For normalising the PURL, I think I'd do it in three steps:
1) remove the "http://www.university.edu.proxyrewrite.proxy.edu/auth/EZProxy.asp?url=" string if present
2) remove ".proxyrewrite.proxy.edu" if present
3) prepend "http://www.university.edu.proxyrewrite.proxy.edu/auth/EZProxy.asp?url="

Feel free to email me if you need more information - I'm not sure how familiar you are with javascript.

Deborah

Subject: [CODE4LIB] PURL normalizer script

Hi,

Has anyone created a script to help normalize PURLS that go through the EZProxy rewrite, that they would be willing to share?

The script would have to be smart enough to do the following:

1. Prepend the proxy prefix url if it does not exist.
2. Remove the proxy rewrite from either the proxy prefix and/or the vendor's url.

For example, a sample url would be:

http://www.university.edu.proxyrewrite.proxy.edu/auth/EZProxy.asp?url=
http://search.ebscohost.com.proxyrewrite.proxy.edu/login.aspx
?direct=true&db=a9h&AN=66352991&site=ehost-live

In this example, the proxy prefix is already there, but the rewrite, ".
proxyrewrite.proxy.edu" exists in two places and would need to be removed.

I visualize a web form that the patron would copy/paste the url into the text box and click button and new, working url will be there for user to use for future use.
