[xwiki-devs] Enhancing Static/Dynamic List type property by custom code/SPARQ query

Hello, I'm currently in a need to have a dynamically created list in authoring template. The list will be generated by SPARQ query which will run against Jena's SDB storage. Sidenote: we have loosely integrated XWiki and Jena to provide some kind of semantic XWiki. This is done by custom macros w/o any special kind of syntax. This is perhaps some of later steps to do. Now, we would like to come with special forms/templates for creating pages for customer defined constructs. Since some of the constructs properties depends on another constructs properties, ideally I'd like to either enhance dynamic or static list (if static is an option here) or write another dynamic list with a support for executing custom groovy code or even SPARQ query directly. My question is: what do you think is the easiest way (whole our project is still at the prototype level) to achieve this functionality? Also where exactly shall I go inside the source code to find the required code? Thanks a lot for any hint! Karel
