I currently run a custom-built small-scale 'repository' of learning objects, a very basic interface to which is at http://www.nottingham.ac.uk/nursing/sonet/rlos/rlolist.php. It's a mySQL database queried by PHP scripts. I'd like to expose the learning object records in the database as a XML file for harvesting and/or SRU querying, but I really, really don't fancy writing the PHP code from scratch and studying the OAI-PMH and SRU protocols in eye-scrunching suicide-inducing detail. As plenty of repositories expose their records this way I figure that there must be PHP libraries/classes which I can use, so could someone here point me towards them. And perhaps to something like "A PHP developers guide to exposing data in XML"? I suspect that this might be the wrong list to ask, but I'm reluctant to post the query to web-support as although folk there know plenty about PHP/mySQL they'll be mostly ignorant of metadata protocols like OIA-PMH, SRU, CDM and bar.
