Grieth,

I've created a basic translator for AustLII (http://www.austlii.edu.au/) that you can build upon.

Step 1: Download and install Zotero's Scaffold Utility here:
http://dev.zotero.org/docs/scaffold

Step 2: Fill out the "Metadata" tab something like this:
http://mckinney.sw.googlepages.com/scaffold-metadata.png

Step 3: Cut and paste code below into the "Detect Code" tab like this:
http://mckinney.sw.googlepages.com/scaffold-detect-code.png

Step 4: Cut and past code below into the "Code" tab like this:
http://mckinney.sw.googlepages.com/scaffold-code.png

Step 5: Click the "Save to Database" icon on the toolbar (second from left).

Step 6: Test some AustLII cases.

Good luck!
