Materialize: what is an Edge Map and a Property Map?

This question is for a Blender Artist who has some experience with the Materialize app to create various maps from a Diffuse Map (from an image). Among other maps which clearly make sense to me, are 2 more that don’t: the Edge Map and Property Map. What are these and how to use them?

Note: I’m not using this app for creating maps for games, I’m rather interested in architectural visualization, so I don’t know if I need an Edge Map or Property Map at all.

If there is use for these maps, then how to use them in Blender, I mean to what node should I plug them in the material editor in Cycles?
