A document manifest gathers a set of Resources into a single package with some clinical context that may be the subject of workflow such as targeted delivery. The usage of “document” in the case of Document Manifest, covers the broader scope of “document”. This use is not limited to the formal “Document” model used for FHIR documents or DocumentReference resources.
Typically, Document Manifest resources are used in document indexing systems. When used as a Manifest of “Documents” in this way, the Document Manifest will point exclusively to DocumentReference resources.
Fast Healthcare Interoperability Resources (FHIR) is a draft standard describing data formats and elements (known as “resources”) and an application programming interface (API) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organization.
Its goal is to facilitate interoperation between legacy healthcare systems, to make it easy to provide healthcare information to healthcare providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.
FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs (Uniform Resource Locators). FHIR was supported at an American Medical Informatics Association meeting by many EHR (Electronic Health Record) vendors which value its open and extensible nature.
