I coordinate our statewide cultural heritage collections discovery service, TexasHeritageOnline.org. In the past, we've used a variety of approaches to interoperability, including Z39.50, SRU, and custom APIs, but I'm moving more to simple OAI-PMH, because that's what many of the asset management systems support natively. Right now I have at least five large collections that are built as MySQL databases to which I'd like to add OAI-PMH data provider support. The problem is that many of the tools we've identified, like the OAIBiblio tool and the Oldenburg tool, use PHP4, and the folks I'm working with are running PHP5. There's also a need for multi-table support. Does anybody know of newer tools for OAI data provider support? Good documentation would be a plus <g>. I do have a small budget this year for development, so if needed I could contract this out, but I thought I'd see what's available first.
