Hi Léon,

Thanks for your response! I did not have a deeper look but just technically the public-lbd@w3.org mailing list would be a good place to circulate this discussion. If OK I would resend there? Else we are happy to loop back the answers in a group call.

Best and have a nice weekend,

Georg

> It is really nice to present the IFC5 ideas to people who like them. This is not always the case as you can imagine...

> Q [Georg]: IFC 4.3 has been “former” IFC5 (Bridge, Road etc.)?
> --> yes, the original idea of infra/rail/etc wat to extend the schema and release an IFC5. For some reason they decided on 4.3. That was before my time, so I don't know why.
> They should have called it IFC5, since it is quite different from IFC 4.2, but it's too late for that now.
> So now IFC5 is 'the new thing' that everybody is afraid of.
>
> Q [Seppo]: What does “scripting” mean in the context of Léon´s presentation?
> --> IFC 4.3 is currently stored as UML in Enterprise Architect. We are using the internal Enterprise Architect scripting language to transform the structure to IFC5. Andreas Pinzenoehler <andreas.pinzenoehler@iqsoft.com> is the expert with the details.
>
> Q [Joel, Mads]: Property modelling mechanism should be interesting for a follow up.
> --> yes.
>
> Q [Mathias]: SHACL based validation, e.g. as currently done in the Flemish Road Agency publishing SHACL and terminology/vocabulary: https://wegenenverkeer.data.vlaanderen.be/. Looking if this Flemish OTL can be entered/linked in the bSDD Q [Anna]: How definitions are grouped/aligned/validated in bSDD Q [Goncal]: Relation and alignment IFC5 and BOT Q
> --> I love SHACL! But currently there is not really a place for that in bSDD. When you  want these advanced linked data technologies, you should use linked data tools. bSDD is the layman's tool to make some first steps towards publishing data as TTL and have it available over a GraphQL API. The target group are the people who don't understand linked data, but do want to profit from it. Complex linked data technologies are on the backlog of bSDD, but that is years (no, multiple years) away.
> --> the Amsterdam OTL has recently been put in the bSDD. I think I showed it in de presentation. We are even using their URIs. An example can be found on https://search.bsdd.buildingsmart.org/?SearchText=wand&Command=Search&TypeFilter=All&SelectedDomains=%3B16%3B

> [Katja]: How can an engagement of the W3C LBD CG could look like? -Also to be discussed internally-
> Q [Georg]: Is there a plan to revive a “Linked Data @ buildingSMART technical room”? (former Linked Data Working Group inside bSI)
> --> I see the W3C LBD as the group that does Linked Data for IFC (and broader buildingSMART).
> The formal Linked data working group inside bSI where just the same people with a different group name. That never made sense to me.
> I would love to formalize the engagement, but I'm more interested to get things done and make actual progress on the content.

> Hope this is the start of follow up questions again 😊

> Dear Léon,
