Spatial attributes to query tasks

I'm looking at Activiti as a candidate BPMN solution. In my use case, all tasks would have a spatial attribute: mostly a point location, but potential more complex geometries like lines or areas. The idea would be that people can search for and subsequently claim tasks that are within a certain distance from a certain location. Searching for those tasks could be achieved using PostGIS or something similar.

Although I couldn't find anything like this while searching the web, maybe someone already thought about or implemented this functionality in Activiti?

If it doesn't exist yet: Is there an "easy" way to implement this kind of functionality? If so, are there examples that could show me how to extend the activiti engine to support this new attribute type and provide specific query possibilities on the attribute type? Or is the idea of implementing the functionality like this too "intrusive" and is there a more elegant/effective way to do this?

Thanks in advance for any feedback.

Kind regards,
