Squeezing Juice into the OPAC

Those who went to either Richard Wallis’ API session or my OPAC session at the UKSG 2009 Conference will have heard about Richard‘s Open Source Juice Project.

The project, which was launched at Code4Lib 2009, is designed to allow developers to create OPAC extensions (or, if you prefer, “bells and whistles”) that, in theory, should be product independent. This is such a genius idea!

Part of the problem with the stuff we’ve developed at Huddersfield is that we had to put an infrastructure in place around the OPAC in order to allow us to do the tweaking — an extra web server, MySQL databases, etc. It works well for us, but it’s not an easily transferable model. I’m always more than happy to share the “how we did it” but, more often than not, the actual code is too reliant on that back end infrastructure.

I need to do a bit more testing, but I’m hoping to have a HIP 3 “metadef” ready soon. The job of the metadef is to define whereabouts on the OPAC page things like the ISBN, author and title appear, and therefore will be different for every OPAC product. However, once you have a suitable metadef for your OPAC, you can start using the Juice extensions to add extra functionality — I had a quick play around last night just to prove that Juice will work with HIP 3…

I’m not sure if this is in Richard’s plans for Juice, but it would be handy to extend the metadef to include other OPAC specific information — e.g. given an ISBN or some keywords, how do you construct a URL to trigger a search on that OPAC. That’d be really useful for embedding recommendations, etc.
