Construction knowledge is attached to that # skeleton at the place it belongs: # # - a RECIPE on each surface: the ordered layers of the assembly that will realise it; # - a JOINT DETAIL on each edge: how every layer of every surface meeting there terminates, # and what trims run along it; # - an OPENING DETAIL on each opening: the flashings and boards that finish its perimeter; # - REQUIREMENTS on each side of a surface, inferred from the zones it faces. # # Details resolve by specificity — an edge's own joint, else the template for its kind of edge # and pair of recipes, else the project's standard for that kind, else a mitre — so a handful of # templates details a whole building, and the exceptions are stated where they occur. # # The element-level building (members, sheets, boards, insulation, machining) is DERIVED from # the blueprint by a deterministic compilation (twb:Derivation), which is what makes the # blueprint a template of the building rather than a model of it. # # TWB extends the Building Topology Ontology (BOT): a surface is a bot:Element in its thin form; # edges, zone boundaries, zone separations and opening edges are bot:Interface. # # TWB is modular, as SEAS is. Every term is in one namespace, twb: (https://w3id.org/twb#), and is # defined by one module (rdfs:isDefinedBy), an ontology of its own that imports only the modules # it builds on. This file is TWB as a whole: it defines nothing and imports every module.
