<b>General Information</b>
</p>
<p>This is a Public Draft of a document prepared by the Linked Building Data Community Group (<a href="https://www.w3.org/community/lbd/">LBD</a>). The document is prepared following W3C conventions. The document is released at this time to solicit public comment.</p>

<section id="intro" class="informative">
<h2>Introduction</h2>
<p>
Designing, planning, constructing and maintaining a building are tasks that involve multiple stakeholders each having their own interpretations and requirements for the common dataset. Furthermore, each stakeholder consumes, processes and manipulates information about the building during it's full life cycle.
</p>
<p>
Several industries have interfaces to the construction industry and buildings in particular without this being their main industry. As there is often a need to describe some sensor, product, device in the context of the building in which it sits and as the building is itself also a feature of interest in the context of a smart city, there is a demand for a minimal, extendable ontology that describes anything in its context of a building.
</p>
<p>
The Building Topology Ontology (BOT) is a minimal OWL DL [[owl2-primer]] ontology for defining relationships between the sub-components of a building. It was suggested as an extensible baseline for use along with more domain specific ontologies following general W3C principles of encouraging reuse and keeping the schema no more complex than necessary.
</p>
<p>
BOT is from design scoped to describe topology specific to the buildings domain. It does not provide a generic description of topological relationships as, for instance, the Regional Connection Calculus (RCC) [[Randell]]. See also in this regard the discussion in the accompanying publication [[[Rasmussen2020]], Sec. 3.3] .

<h2>Requirements</h2>
<p><em>Section to be consolidated with the Final Draft of the Linked Building Data Community Group Use Cases & Requirements [[LBD-UCR]]</em></p>
<p>This section lists the set of competency questions the BOT ontology answers.</p>
<ol>
<li>Zones are areas with spatial 3D volumes, and include, Buildings, Storeys, and Spaces.</li>
<li>Zones may contain other zones, Buildings may contain storeys, Storeys may contain spaces.</li>
<li>Zones may intersect, or be adjacent to other zones.</li>
<li>There are building elements, which may have sub elements.</li>
<li>Zones may have elements, either contained, adjacent, or intersecting it.</li>
<li>A adjacent zones and/or elements share some interface.</li>
<li>Zones and Elements have a 3D Model (including geometry, material, etc.).</li>

<h3>Zones and sub-zones</h3>
<section class="informative" id="Zones-Overview">
<h4>Overview and Examples</h4>
<p>Zones are defined as a part of the physical world or a virtual world that is inherently both located in this world and has a 3D spatial extent. Four sub types of Zones are defined: </p>
<ul>
<li>Site: An area containing one or more buildings;</li>
<li>Building: An independent unit of the built environment with a characteristic spatial structure;</li>
<li>Storey: A level part of a building;</li>
<li>Space: A limited three-dimensional extent defined physically or notionally.</li>
</ul>

<figcaption>Classes and relationships involved in Zones</figcaption>

<p>
Zones must be understood as a Matryoshka doll principle. The <a href="#Site"><code>bot:Site</code></a>
instance, <siteX>, contains one building, <buildingA>, specified by the <a href="#hasBuilding">
<code>bot:hasBuilding</code></a> relationship. <buildingA> contains one storey, <storey01>,
specified by the <a href="#hasStorey"><code>bot:hasStorey</code></a> relationship. <storey01>
contains two spaces, <spaceA12> and <spaceA13>, specified by the <a href="#hasSpace">
<code>bot:hasSpace</code></a> relationship.
</p>
<ul>
<li>Spaces <spaceA12> and <spaceA13> are adjacent, which is specified by the
<a href="#Site"><code>bot:adjacentZone</code></a> relationship.</li>
<li>The transitive <a href="#containsZone">
<code>bot:containsZone</code></a> relationship is a super-property of both <a href="#hasBuilding">
<code>bot:hasBuilding</code></a>, <a href="#hasStorey"><code>bot:hasStorey</code></a> and
<a href="#hasSpace"><code>bot:hasSpace</code></a> - therefore <siteX> contains all the other
<a href="#Zone"><code>bot:Zone</code></a> instances.</li>
<li>A stairwell would be modeled as a <a href="#Zone">
<code>bot:Zone</code></a>, linked to the different <a href="#Storey"><code>bot:Storey</code></a>s through the <a href="#intersectsZone">
<code>bot:intersectsZone</code></a> relation.</li>
</ul>
<p>
This specification does not restrict what an instance of the <code>bot:Zone</code> class can be. BOT may be used in conjunction with other ontologies to specify this. Examples include:
<p>
<ul>
<li>A category of zones (e.g., office building)</li>
<li>A specification of zones (e.g., office buildings with energy efficiency class above A)</li>
<li>An actual zone (e.g., the kitchen in Marc's home)</li>
</ul>

<h4>Overview and Examples</h4>
<p>
Building elements are physical parts of building constructions. Examples of elements include walls, doors, pipes, heaters, lights, smart sensors, tables, chairs.
</p>
<p>
Elements can contain sub elements. Zones can contain elements, or be adjacent to elements.

This specification does not restrict what an instance of the <code>bot:Element</code> class can be. BOT may be used in conjunction with other ontologies to specify this. Examples include:
<p>
<ul>

<h3>Interfaces</h3>
<section id="Interfaces-overview" class="informative">
<h4>Overview and Examples</h4>
<p>
Interfaces are used in situations where it is necessary to quantify a relationship between
two elements or zones or an element and a zone. The following figure provides an overview of the core classes
and properties that are specifically related to modeling Interfaces.
</p>
<figure>
<a href="assets/interfaces.png"><img alt="Interfaces" src="assets/interfaces.png"></a>
<figcaption>Classes and relationships involved in Interfaces</figcaption>
</figure>
<p> In the figure, there are two
<a href="#Zone"><code>bot:Zone</code></a> instances that are both adjacent to the same
<a href="#Element"><code>bot:Element</code></a> instance <wall22>. To quantify
the heat transfer areas between <spaceA12>/<wall22> and <zoneB>/<wall22>
respectively, two interfaces, <interfaceA> and <interfaceB>, are introduced.
Both interfaces are related to <wall22> through the <a href="#interfaceOf"><code>bot:interfaceOf</code></a>
relationships, but their second <a href="#interfaceOf"><code>bot:interfaceOf</code></a> relationship is to
either <spaceA12> or <zoneB>.

A generic concept to qualify the relationship of two or more things in the world, where at least one is a building element or zone. Examples: (1) Qualification of heat transmission between zones through one or more building elements. This includes one-dimensional (surface) heat losses from one zone to another through a single building element, a two dimensional (line) loss from one zone to another through the connection in which the two elements meet or a three dimensional (point) loss from one zone to another through the connection where three elements (typically two walls and a slab) meet. (2) Connection of an electric device to the electric system of a building. (3) A door between one room and another.</span>

<h3>3D Model</h3>
<section id="3DModel-overview" class="informative">
<h4>Overview and Examples</h4>
<p>
Any <a href="#Zone"><code>bot:Zone</code></a> or <a href="#Element"><code>bot:Element</code></a> can be assigned a 3D Model (including geometry, material, etc.), using some <a href="https://www.iana.org/assignments/media-types#model">existing data format for 3D models</a>. Two properties are defined for this:
</p>
<ul>
<li>The <a href="#hasSimple3DModel"><code>bot:hasSimple3DModel</code></a> datatype property links a <a href="#Zone"><code>bot:Zone</code></a> or <a href="#Element"><code>bot:Element</code></a> to a 3D Model encoded as a literal. Note that we encourage the use of URIs for mediatype with the IANA authority. For example <a href="https://www.iana.org/assignments/media-types/model/3mf"><code>https://www.iana.org/assignments/media-types/model/3mf</code></a> for the mediatype <code>model/3mf</code>. Other mediatypes for OBJ, STP, IFC, W3D, etc. can be defined. If the data format is textual, then the lexical form of the 3D Model literal SHOULD be encoded as a Unicode [[!UNICODE]] string, which SHOULD be in Normal Form C [[!NFC]]. If the data format is binary, then the lexical form of the 3D Model literal SHOULD be encoded using a base32 encoding [[!rfc4648]].</li>
<li>The <a href="#has3DModel"><code>bot:has3DModel</code></a> object property links a <a href="#Zone"><code>bot:Zone</code></a> or <a href="#Element"><code>bot:Element</code></a> to some IRI that identifies a 3D Model. This 3D Model can then be described using some dedicated RDF vocabulary. Else, the 3D Model IRI could be dereferenceable, and when looking up the IRI one could retrieve a representation of the 3D Model with some <a href="https://www.iana.org/assignments/media-types#model">existing data format for 3D models</a>. </li>
