For example, metadata can provide a variety of information regarding a document such as author, date revised, relevant key words, etc. As another example, metadata might annotate X3D CAD geometry to provide key references such as part numbers, documentation references, inventory links, etc. </p> <p> Simple name=value paired information can be provided in document <code>&lt;<a href="https://www.web3d.org/x3d/content/X3dTooltips.html#head" target="X3dTooltips">head</a>&gt;</code> and <code>&lt;<a href="https://www.web3d.org/x3d/content/X3dTooltips.html#meta" target="X3dTooltips">meta</a>&gt;</code> tags, just like in HTML. Furthermore, typed metadata information can annotate any X3D node, either for use offline or for queries within an active scene graph at run time.
