update definition of bot:Site #54

Closed mathib closed 4 years ago

mathib commented 4 years ago

As mentioned in https://github.com/w3c-lbd-cg/bot/issues/38. The current definition of bot:Site says:

Site - Area containing one or more buildings.

A bot:Site is however a subclass of bot:Zone and also corresponds has a spatial 3D extent. Therefore, the definition in BOT should be updated to better reflect this. Proposal:

Site - a spatial 3D object containing one or more buildings

Maybe there should also be a reference to a standard defining the concept of site in a similar way? I'm unsure if there should be a closer connection to the human concept of "parcel"?

@GeorgFerdinandSchneider : the definition of bot:Site itself is not (yet?) updated by #59 . Was this discussed in the calls? I'll also add a relevant comment from Rui @deKlerk in the Google spreadsheet with the translations:

there are sites without buildings, but they're still sites. suggestion: "Area intended for building, which may contain one or more buildings.":

mathib commented 4 years ago

Also bot:Storey(and maybe even bot:Building) text definitions should probably be updated to incorporate the notion of spatial extent

Hi Mathias,

You are right, I'm reopening this issue.

You're probably right that the definition of Site needs to be updated as well. maybe other.

What about

A part of the physical world or a virtual world that is inherently both located in this world and having a 3D spatial extent, and is intended to contain one or more buildings.

mathib commented 4 years ago

The new definition for bot:Site sounds good for me! Probably should be discussed in the upcoming LBD call. I'll make separate issues for bot:Building and bot:Storey

GeorgFerdinandSchneider commented 4 years ago

A comment received by Rui de Klerk @deKlerk: "Area intended for building, which may contain one or more buildings."

Hence I suggest to change the description proposed by Maxime to:

A part of the physical world or a virtual world that is inherently both located in this world and having a 3D spatial extent, and is intended to contain zero or more buildings.

mathib commented 4 years ago

how can a site that's "intended to contain zero buildings" be a building site? :)

GeorgFerdinandSchneider commented 4 years ago

I would argue it can. Logically there should also be no probles (we do not have cardinality restrictions)

An empty site prior to construction is a site without a building. Happens often in green field construction

mathib commented 4 years ago

I just wanted to stress intended in the definition. This means that it can be empty, but there's at least the intention to make a building on it. Consider an agricultural site: there's no intention to make a building here, thus it's not a building site

GeorgFerdinandSchneider commented 4 years ago

+1 good you pointed the intended out.

How about:

A part of the physical world or a virtual world that is inherently both located in this world and having a 3D spatial extent, and is intended to or contains one or more buildings.

maximelefrancois86 commented 4 years ago

This last definition seems perfect to me

A part of the physical world or a virtual world that is inherently both located in this world and having a 3D spatial extent, and is intended to or contains one or more buildings.

Comment received at the W3C LBD CG meeting by Slyvain Marie: Sylvain MARIE 17:17 Also, ISO already provides: " ISO6707-1 vocabulary "area of land or water where construction work or other development is undertaken". It's more concise ?

Current proposal agreed on in W3C LBD CG TelCo @ 23 April 2020, confirmed on in W3C LBD CG TelCo @ 19 May 2020:

A part of the physical world or a virtual world that is inherently both located in this world and having a 3D spatial extent. It is intended to contain or contains one or more buildings.

What about a building/zone that is not yet built, so it is not yet "inherently located in this world."

answer by @GeorgFerdinandSchneider : We had this discussion. The virtual world is considered a part of this world
