<p><strong>BIM Collaboration Format</strong> (BCF) is a standard by buildingSMART to manage and
exchange coordination topics between disciplines collaborating on a project.
For example, when there is an issue during the design, engineering, or
construction of a project, a topic may be created, assigned, prioritised,
commented, or linked to objects in a BIM model or camera location.</p>
<p>There are two implementations of BCF:</p>
<ol class="arabic simple">
<li><p><strong>BCF-XML</strong>: an XML file-based exchange of collaboration topics. This is
useful for mass imports, exports, data migration across CDEs, or fully
offline implementations.</p></li>
<li><p><strong>BCF-API</strong>: an online RESTful API-based management of collaboration topics.
When topics are managed by a CDE, if the CDE follows the OpenCDE
specification by buildingSMART, their topics may be accessed and manipulated
using BCF.</p></li>
</ol>
<p>The upstream documentation by buildingSMART for BCF is available here:</p>
<ol class="arabic simple">
<li><p><a class="reference external" href="https://github.com/buildingSMART/BCF-XML/tree/release_2_1/Documentation">BCF-XML 2.1 upstream documentation</a>.</p></li>

<li><p><a class="reference external" href="https://github.com/buildingSMART/bcf-api">BCF-API 3.0 upstream documentation</a>.</p></li>
</ol>
<p>The IfcOpenShell <strong>BCF</strong> library supports BCF-XML version 2.1 and 3.0, and
