Forum OpenACS Q&A: Is anyone here using OAI-PMH? (The Open Archives Initiative Protocol for Metadata Harvesting)

We've been asked to tender on a job that will require us to extract data from an existing Voyager database using OAI-PMH. Has anyone here had to interface with this sort of collection management database in the past? We're still trying to decide if the job is worth going for, and dealing with the Voyager system is the biggest unknown in the equation - if anyone here has experience with this sort of setup I'd love to have a chat about it.
OAI-PMH is pretty easy stuff if you do not go for full XML Schema validation, pretty easy to do in Tcl with tDOM or any other XML parser.

We use it to search and connect to a wide range of library systems (with a PHP implementation of OAI-PMH).

I don't know Voyager, but if it can spit out Dublin Core Metadata your already there, otherwise the major task is the creation of a scheme to convert the internal metadata to the mandatory dc standard.
