ResearchElementDefinition (DomainResource)An absolute URI that is used to identify this research element definition when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which at which an authoritative instance of this research element definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the research element definition is stored on different serversurl : uri [0..1]A formal identifier that is used to identify this research element definition when it is represented in other formats, or referenced in a specification, model, design or an instanceidentifier : Identifier [0..*]The identifier that is used to identify this version of the research element definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the research element definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification.

ResearchElementDefinition (DomainResource)An absolute URI that is used to identify this research element definition when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which at which an authoritative instance of this research element definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the research element definition is stored on different serversurl : uri [0..1]A formal identifier that is used to identify this research element definition when it is represented in other formats, or referenced in a specification, model, design or an instanceidentifier : Identifier [0..*]The identifier that is used to identify this version of the research element definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the research element definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification.
