ifc-template-catalog

Typed import, validation, query, correction overlays, and deterministic embedded snapshots for buildingSMART PSD/QTO template catalogs.

Embedded editions and profiles

Official snapshots are embedded for IFC2X3 TC1, IFC4 ADD2 TC1, and IFC4X3 ADD2. Corrected overlays are deliberately available only for IFC4 ADD2 TC1; official artifacts are never rewritten.

Version-explicit TSV index

Each committed TSV has an edition and source_digest column, preserves set/member GUIDs when the source publishes them, and retains the source XML path and digest. GUIDs are release-scoped evidence, not a promise that equal names or GUIDs have identical semantics across editions. Generate one deterministically:

cargo run -p ifc-template-catalog --example export_ifc4_tsv -- \
  ifc4x3-add2 ifc-template-catalog/data/ifc4x3-add2.tsv

The example accepts ifc2x3-tc1, ifc4-add2-tc1, or ifc4x3-add2. Provenance, exact corpus gates, checksums, and artifact sizes are in data/NOTICE.md.
