A <strong>Compatibility Base</strong> is a database entity that is characterized by <a href="/public/software/dazstudio/4/referenceguide/terms/metadata/start" class="wikilink1" title="public:software:dazstudio:4:referenceguide:terms:metadata:start">metadata</a>, and functions as the shared identifier linking groups of <a href="/public/software/dazstudio/4/referenceguide/terms/compatible/start" class="wikilink1" title="public:software:dazstudio:4:referenceguide:terms:compatible:start">compatible</a> entities.
</p>
<p>
The purpose of a compatibility base is to facilitate a many-to-one-to-many relationship between <a href="/public/software/dazstudio/4/referenceguide/terms/asset/start" class="wikilink1" title="public:software:dazstudio:4:referenceguide:terms:asset:start">assets</a> that are compatible with each other, as well as with objects present in the scene.
</p>
<p>
An object in the scene may declare that it is the embodiment of a discrete compatibility base by associating its <a href="/public/software/dazstudio/4/referenceguide/terms/scene_identifier/start" class="wikilink2" title="public:software:dazstudio:4:referenceguide:terms:scene_identifier:start" rel="nofollow">scene_identifier</a> with the compatibility base. This relationship can be established using the <a href="/public/software/dazstudio/4/referenceguide/interface/action/index/dzhpsceneideditoraction/start" class="wikilink1" title="public:software:dazstudio:4:referenceguide:interface:action:index:dzhpsceneideditoraction:start">Scene Identification...</a> action.
</p>
<p>
An asset may declare that it causes an object to load into the scene, and that the object is the embodiment of a discrete compatibility base. An asset may independently declare that it is <em><a href="/public/software/dazstudio/4/referenceguide/terms/compatible/start" class="wikilink1" title="public:software:dazstudio:4:referenceguide:terms:compatible:start">compatible</a> with</em> a particular compatibility base. These declarations can be established through the <a href="/public/software/dazstudio/4/referenceguide/interface/action/index/dzcontentdbeditoraction/start" class="wikilink1" title="public:software:dazstudio:4:referenceguide:interface:action:index:dzcontentdbeditoraction:start">Content DB Editor...</a> action.
