BIM-CVP wiki.
Start with the concept, then the standards, then the event model. Larger subjects have dedicated pages. Smaller details live in collected reference notes until they deserve their own page.
Understand
What problem are we solving?
- What is BIM and openBIM Model vs file, open standards, and why building data must outlive tools.
- The platform problem Why openBIM data still gets trapped in vendor portals and project silos.
- BIM-CVP protocol framing Common Value Protocol, Austrian economics framing, Nostr and signed responsibility.
- Alice, Bob, Max A concrete story showing how project records link together as signed, verifiable events.
Standards
What do we build on?
- buildingSMART International The main source map: IFC, BCF, IDS, bSDD, openCDE, validation and UCM.
- Pinned standards profile The exact versions used for implementation and tests.
- IFC The building model as structured data, including schema and identity rules.
- BCF Topics, comments, viewpoints and the coordination format BIM-CVP extends.
- IDS Machine-checkable information requirements for IFC delivery.
- ISO 19650 The process frame: roles, requirements, states and approvals.
Event model
How do standards become signed records?
- Workflow model End-to-end process: project setup, model publishing, coordination, validation and approval.
- BCF to Nostr events Detailed event kinds, tags, examples, queries and round-trip rules.
- Kind registry Every event kind used by BIM-CVP across BCF, IFC, IDS and lifecycle records.
- Nostr basics Keypairs, signatures, relays, NIP-07 and why this is not a blockchain.
Reference notes
Small topics grouped in one place.
The field guide is no longer a main learning path. It is a holding area for smaller reference notes that do not need a dedicated page yet.
- Model notes IFC layers, core entities, property sets, quantity sets and MVDs.
- Coordination notes BCF-XML, BCF-API and openCDE integration boundaries.
- Requirements notes LOIN, PIR/EIR/AIR/OIR and IDM process references.
- Dictionary and lifecycle notes bSDD, classification systems, AIM, building logbook and DPP.
Profiles
Regional and client overlays.
Profiles adapt terminology, procurement references, phase names and client exchange gates. They must not change the core BIM-CVP event model.
- Switzerland profile Bauen digital Schweiz, KBOB, BIM-Abwicklungsmodell, glossary and BIM2FM.
- Regional profile notes Short notes for DACH, Italy and other local implementations.
Next architecture
Nostr relay wiki.
A relay-backed wiki can add signed authorship and portable editing. The public site remains the stable reading surface; relay events can become the signed source layer behind it.
- Event basics Use signed authorship and relays for publication.
- Protocol fit Long-form Markdown pages fit Nostr addressable events.
