3. What are standards? What kind of standards do we have?

4. Digitalization of paper documents Doing the same, but digital 02 03 04 01 PDF, ZIP, etc

5. Digitalization of paper documents Doing the same, but digital Syntactical interoperability Making sure documents can be read by computers, but computers don’t really understand what is in them. 02 03 04 01 PDF, ZIP, etc HTML, PDTs, XML, JSON, etc

6. Digitalization of paper documents Doing the same, but digital Syntactical interoperability Making sure documents can be read by computers, but computers don’t really understand what is in them. Semantic interoperability Making sure documents can be read by computers, and computers understand the content. 02 03 04 01 PDF, ZIP, etc HTML, PDTs, XML, JSON, etc IFC, BCF, ETIM, Uniclass, etc

7. Digitalization of paper documents Doing the same, but digital Syntactical interoperability Making sure documents can be read by computers, but computers don’t really understand what is in them. Semantic interoperability Making sure documents can be read by computers, and computers understand the content. Linked Semantic Data Linking and creating relations between semantic data definitions over multiple domains 02 03 04 01 OWL, OTL, bSDD PDF, ZIP, etc HTML, PDTs, XML, JSON, etc IFC, BCF, ETIM, Uniclass, etc

18. ©2020 buildingSMART International, Ltd., All Rights Reserved Information Delivery Specification BCF Topics Common & Integrating parts: Common API Query language Quality assurance Deployment Tools bSDD API openCDE API BCF API File serialisations (json, RDF, xml, spff, etc)

22. Desired situation • One interoperable IFC • Multiple file serializations • Filtering / querying (partial data sets) • API access • Extendable • Multi domain interoperability “by design” • Ecosystem • Validation tools • Meta standards (IDS, BCF, etc) • Certification that provides guarantees ©2020 buildingSMART International, Ltd., All Rights Reserved

23. Desired situation • Predictable development • Transparent, traceable • Standards roadmap (for example: “10 principles of IFC”) • Automated & transparent quality assurance • Low threshold for implementation (mainstream modelling techniques, high quality documentation, etc) • Semantic harmonisation / connection • With bSDD • With national / use-case specific standards • With other domains (Geo) •  bSDD ©2020 buildingSMART International, Ltd., All Rights Reserved

24. Example topics • Use-case based implementations  generic IFC implementations • Demarcated files  open ended datasets (extendable) • Strong link to STEP/EXPRESS  generic modelling techniques • Growing monolithic agreement  modularity • Ascending release cycle times  LTS base + shorter releases for modules • Waiting for updates (surprise!)  public/transparent development (with ability to check and contribute) • High threshold for connecting your standard  lower threshold for usage ©2020 buildingSMART International, Ltd., All Rights Reserved

26. The main issue • Usability • Predictability • Reliability • Transparency • Traceability ©2020 buildingSMART International, Ltd., All Rights Reserved Technology influenced Organisation (culture) influenced

71. “10 principles of IFC” https://github.com/buildingSMART/NextGen-IFC/wiki/Ten-principles-for-a-future-IFC • Follows contemporary approaches and standards • Favors simplicity over complexity • Has no single-purpose definitions • Strives for interoperability and has no competing modeling paradigms • Appropriateness • Versatility • Clarity • A reduced implementation effort for (a) authoring (b) importing • Harmonious and consistent • Modularity ©2020 buildingSMART International, Ltd., All Rights Reserved

All of them require: - Agreements on what we mean with things  Semantic Data standards (“when is it a room or a hallway?”) - Agreements on how to exchange things  Syntax standards (“do you want XML or JSON?”) - Agreements on how to find and access things  Meta data and API standards (“what do you have?”)
