69. Building Definition Language
Stable section ID: S05-CON-015-SECTION-70 · 14 content blocks
The Building Definition Language (BDL) is the controlled human- and machine-readable language used to describe the intended organization, functions, geometry, Interfaces, configurations, requirements, constraints, and lifecycle characteristics of a System05 Building.
BDL may represent:
spatial and functional organization;
systems, Modules, and Assemblies;
Node, Cartridge, and Interface requirements;
performance and environmental classes;
configuration options and dependencies;
regional and project Profiles;
assembly and lifecycle intent;
verification and evidence requirements.
BDL describes engineering intent rather than only graphical geometry. It shall preserve semantic meaning across authorized software, AI, manufacturing, inspection, and robotic systems.
A BDL document shall possess a declared schema, version, dependencies, units, coordinate references, and authoritative status.
BDL shall remain distinct from the Building BIOS. BDL expresses the source definition and intended configuration; the Engineering Compiler evaluates and transforms that definition; the BIOS records the approved and verified operational configuration.
A valid BDL document does not independently constitute structural approval, regulatory acceptance, or authorization for construction.
