A few years ago, I was working with a Microsoft customer to deploy a Microsoft Office SharePoint Server (MOSS 2007) solution. SharePoint 2007 had just been released at the time. The customer needed document URLs stored in SharePoint to continued to work even after the document was renamed or moved. I blogged about the issue and a potential solution at http://blogs.technet.com/josebda/archive/2006/12/23/unique-document-urls-in-moss-2007.aspx

I was glad to learn recently that, in the upcoming release of SharePoint (MOSS 2010), this is going to be part of the product. This is described at http://msdn.microsoft.com/en-us/library/ee559302(office.14).aspx and also at this great blog post at http://blogs.technet.com/blairb/archive/2009/10/20/new-document-id-feature-in-sharepoint-2010.aspx.

My old blog post was actually something that got over 12,000 hits over the years and I got a few e-mails about this specific blog post asking for details. I guess that was my own "that was totally my idea" moment :-). I did relay that feedback to the product team then. But, to be honest, I can imagine that this was probably something they heard from a number of people...
