Terminologies

NFDI4Health aims to foster the use of international standards whenever and whereever possible. Besides national and international terminologies, some project-specific CodeSystems were defined.

FHIR Code Systems

URI	Definition (from FHIR)	Comment	OID
http://hl7.org/fhir/spdx-license	The license that applies to an Implementation Guide (using an SPDX license Identifiers, or 'not-open-source'). The binding is required but new SPDX license Identifiers are allowed to be used (https://spdx.org/licenses/).	A selection of codes is used in combination with codes from UMLS to express the type of license of a resource in Value Set NFDI4Health_VS_MDS_Use_Rights_Label_SPDX_UMLS_Local	2.16.840.1.113883.4.642.4.1027
http://terminology.hl7.org/CodeSystem/v3-ParticipationType	A code specifying the meaning and purpose of every Participation instance. Each of its values implies specific constraints on the Roles undertaking the participation.	Used in combination with NFDI4Health' defined values to express the activity of a participant in a Provenance resource in Value Set NFDI4Health_VS_MDS_Provenance_Activity_HL7_Local	2.16.840.1.113883.5.90

Internal Code Systems

The following code systems have been created by NFDI4Health to represent concepts without mapping to concepts from international standards:
