Among the scientific goals of the EU-FP7 VIALACTEA project, there are some related to the archiving, discovering and accessing catalogues of infrared/sub-mm objects that are not simple point-like sources on the sky, but compact or diffuse structures. These structures may have more general shapes, bubble-like or filament-like the two categories identified by the project. Also, alongside catalogue search and access, a service to match compact sources that are located inside a more diffuse structure like a bubble or a filament, is needed. In this contribution we describe the scenario and catalogues related to the project scientific tasks and the solutions put in place to grant the VIALACTEA (and astrophysical community) users interaction with these compact and diffuse object catalogue data. Topics span from shape and contour archiving inside a catalogue to fast catalogue cross-matching using tessellation solutions.
