Intersection of ror-organization-creation-date: FHIR Resource Structure Definition

Details

This document is part of a specification defining how extensions are used within the context of FHIR (Fast Healthcare Interoperability Resources). The subject is the 'Intersection' of the structure definition named 'ror-organization-creation-date'. This indicates that the resource must satisfy two different aspects (or sides) of the same resource type simultaneously. The intersection sets detailed rules regarding constraints and handling of extension fields applied to FHIR elements. Key technical points include: all FHIR elements must have either a `@value` or children (ele-1); furthermore, for extension fields, only one of 'extensions' or 'value[x]' may exist. A URI identifier and a date type value are also defined, providing guidelines to maintain strict data structural integrity. Such detailed specification definitions are crucial for ensuring interoperability when exchanging medical information across different systems or departments. It is particularly necessary when handling complex data that has multiple aspects, such as organizational information or event dates, requiring the use of a unified data structure.
