Admin Items are the containers in which content is managed in Listpoint. The rather obscure name comes from the International Standard for Metadata Registries (ISO11179) on which much of Listpoint is based. Admin Items are version controlled metadata objects but it is easier to understand them through their subtypes:
- A Code List (aka CV Set) is a collection of Constrained Values (sometimes called enumerations), some structural information recording how they relate to each other, some data quality rules and other associated metadata;
- A Context represents the configuration of a particular application system or data standard. It comprises a collection of Data Types. A Context is similar to an iPod playlist in that it records a collection of Code List that are relevant to a particular user community. Each choice from the pool of Code Lists held is recorded as an EDT, which also records any filters, selection and sorting choices that have been chosen to modify the raw Code List to suit the needs of the consuming Context (e.g. excluding obsolete codes perhaps).
- A Context Map is a collection the Code Maps that are required to translate codes used in a Source Context into the equivalent codes in a Target Context. This is used when building an interface between two applications.
In future, additional subtypes of Administered Item may be added to Listpoint such as Event (being an expression of the structure of a data record passed between two Contexts in response to some defined stimulus).
