Any help would be very welcome. Here are some things that I would take into consideration, not related to the technical OpenURL question, but I think relevant anyhow. a) What will people do if the service that you provide goes away? A good thing about the OpenURL that you have above is that even if your resolver no longer works, a savvy user can see that the OpenURL is supposed to point at http://www.bbc.co.uk/. A bad thing about the old URL that you have on your blog: <http://routes.open.ac.uk/ixbin/hixclient.exe?_IXDB_=routes&_IXSPFX_=g&submit-button=summary&$+with+res_id+is+res9377> is that when that URL stops working - & I will bet money it will stop working before www.bcc.co.uk stops working - nobody will know what it meant. b) How can you ensure that your service will not go away? What is the institutional commitment? If you can’t provide a stronger commitment than, e.g., www.bbc.co.uk, is this worth doing? c) Who will maintain that database that redirects www.bbc.co.uk to www.neobbc.co.uk? (see second part of B above). d) Is there a simpler solution to this problem than OpenURL? e) Finally: how many problems will this solve? It seems to me that this is only useful in the case of URL A1 moving to A2 (e.g., following an organization rename) where the organization does not maintain a redirect. In other words, it is not particularly useful in cases where URL A1 goes away completely (in which case there is no unarchived URL to go to) and where a redirect is maintained from A1 to A2 (in which case there is no need to maintain your own redirect). How many instances of this are there? Maybe there are many; www.bbc.co.uk is a bad example, but a journal article online might move around a lot. Hope that is useful!
