To allow a single Smart 3D Plant Web API web server to support access to multiple plants, the metadata is partitioned. The root (or site) metadata contains the metadata that is defined in the delivered Smart 3D schema. The schema is accessed by:
GET <ServiceRoot>/$metadata
If the user adds properties to a class in the schema for a model, these new properties are kept in a separate "plant" metadata partition. The plant metadata can be accessed by
GET <ServiceRoot>/Sites('MySiteAlias')/Plants('MyPlant')/$metadata
