Types of Artifacts


A Profile is a definition of a data structure designed to hold certain types of data for a specific use case. A populated instance of a data structure can be validated to confirm that the information conforms to a named or asserted profile.


An extension is a component data element that is added to an existing data structure to expand the type or quantity of information that can be conveyed within the existing data model.

Search Parameters

A search parameter defines a named search item that can be used to search/filter on a resource.
