She co-developed xqOAI with me. I'm not sure if they're still running the code, or this version of the code, though. You might contact her at: winona.salesky@uvm.edu Good luck. And if you have any patches, I'd be willing to incorporate them, or start up an eXist branch if you figure out what the syntax errors are. It has been a few years since I touched the code, but it worked on X-Hive/DB at that point. @Rolf:

The version of the code I am using is what is available on http://code.google.com/p/xqoai/. Did anyone ever pursue an eXist version ?

I may have been too hasty in pointing fingers. :) I'm testing on a server running X-Hive 7.4. Not sure what version of eXist Winona has up. Martin, thanks for your comment.

Are you sure you're using a current version of both?

I wonder which one (if not both) deviates from the 1.0 spec. If we could come up with some style conventions that handle the differences, that would be fantastic. As for resumptionTokens, we kicked around a number of different ways of handling them. Ultimately, if we're designing an OAI-PMH provider for native XML databases, we think it might be best just to do it all in within the NXD, using something like XUpdate to store and manage cached result sets. It's an open question and I'd be interested in your thoughts on the matter. Good point about the different XQuery syntaxes. I wonder which one (if not both) deviates from the 1.0 spec.

So there may need to be a little tweaking there. I imagine that UVM will be able to use this mostly out of the box, except for needing resumption tokens, and the X-Hive/eXist differences (which sound fairly minor). I'll let you know how it goes when I finally get around to testing it. Hi Mike,
