Introduction
The Swedish National Catalog of Organization, Offerings and Contracts is to a large extent based on coded values published as terminologies, later referred to as code systems and value sets (see List of all ValueSets for a complete list of the value sets used in the catalog). Code systems and value sets are used within elements of the type code. Coded values are used in many FHIR resources, e.g. Organization, Location etc. to structure the information and make it system readable. The content of code systems and value sets define a set of values in a specific context. The expression code is commonly also called term or concept and is a structured and often standardized way of expressing a value e.g. mg for milligram.A code system / value set can represent codes from a wellknown terminology e.g. Snomed CT, or locally defined codes.The picture below shows how the binding to code systems or value sets can be seen in a FHIR profile elements. In this case, the profile HVOBusiness has an element with a binding (1) to the value set hvo-business-category (2) which defines all valid codes for the element.http://electronichealth.se

are defined by the Swedish eHealth Agency and can be fetched from the endpoint [base]/ValueSet
. Value sets and code systems defined by other organisations are usually not republished by the Swedish eHealth Agency. The identity of a value set or code system can take many forms, e.g. OID, URI etc. An URI identity may in some cases be used as an URL as well, and make it possible to look up and view the concepts by a browser.
