Context: this is a proposal from Google based on our review of the draft (i.e. Pending) definitions for /FloorPlan and nearby terms.

This proposal adds a /layoutImage to /FloorPlan as specified earlier in #2373

Noting that FloorPlan is place-related but an /Intangible rather than a /Place subtype (and therefore not currently supporting /photo) we propose adding a dedicated property more specific than /image to capture FloorPlan-specific imagery. This is a little unusual in that we don't expect schema.org needs properties for all the infinite range of things that can be depicted online; however the type FloorPlan itself is inherently image-oriented and it seems valuable to distinguish floorplan imagery from other images of rooms and apartments.

• /layoutImage "A schematic image showing the floorplan layout."
• domainIncludes: FloorPlan; rangeIncludes: ImageObject, url
• super-property: /image
