In some situations, "uncontrolled" names are not sufficient to describe the classes or concepts being described or represented by a model. To provide this context, the https://github.com/stac-extensions/themes extension can be used, which the corresponding themes property as defined by OGC API - Records.
The best practices section should refer to this extension to motive its application by users describing a model with MLM, to ensure the concepts are tied properly in the STAC ecosystem.
