268 -This package defines the [[structure>>doc:IMElements.structure.WebHome]] that supports the definition of and relationships between categories in a category scheme. It is similar to the package for concept scheme. An example of a category scheme is one which categorises data – sometimes known as a subject matter domain scheme or a data category scheme. Importantly, as will be seen later, the individual nodes in the scheme (the “categories”) can be associated to any set of IdentiableArtefacts in a [[Categorisation>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Categorisation.WebHome]].
