Information Tracking
Collecting information, and tracking change to the information
NameAliasesDescription
QuestionnaireForm, CRFA structured set of questions intended to guide the collection of answers. The questions are ordered and grouped into coherent subsets, corresponding to the structure of the grouping of the underlying questions.
QuestionnaireResponseFormA structured set of questions and their answers. The questions are ordered and grouped into coherent subsets, corresponding to the structure of the grouping of the underlying questions.
ProvenanceHistory, EventProvenance of a resource is a record that describes entities and processes involved in producing and delivering or otherwise influencing that resource. Provenance provides a critical foundation for assessing authenticity, enabling trust, and allowing reproducibility. Provenance assertions are a form of contextual metadata and can themselves become important records with their own provenance. Provenance statement indicates clinical significance in terms of confidence in authenticity, reliability, and trustworthiness, integrity, and stage in lifecycle (e.g. Document Completion - has the artifact been legally authenticated), all of which may impact security, privacy, and trust policies.
AuditEventA record of an event made for purposes of maintaining a security log. Typical uses include detection of intrusion attempts and monitoring for inappropriate usage.

Documents & Lists
Management of documents and other organizing structures
NameAliasesDescription
CompositionA set of healthcare-related information that is assembled together into a single logical document that provides a single coherent statement of meaning, establishes its own context and that has clinical attestation with regard to who is making the statement. While a Composition defines the structure, it does not actually contain the content: rather the full content of a document is contained in a Bundle, of which the Composition is the first resource contained.
DocumentReferenceA reference to a document .
DocumentManifestA manifest that defines a set of documents.
ListCollection, WorkingListA set of information summarized from a list of other resources.

Structure
Resources that provide basic structural support for other usages
NameAliasesDescription
BinaryPure Binary Content - opaque to FHIR
BasicZ-resource, Extension-resourceBasic is used for handling concepts not yet defined in FHIR, narrative-only resources that don't map to an existing resource, and custom resources not appropriate for inclusion in the FHIR specification.
BinaryA binary resource can contain any content, whether text, image, pdf, zip archive, etc.
BundleA container for a collection of resources.
MediaA photo, video, or audio recording acquired or used in healthcare. The actual content may be inline or provided by direct reference.

Exchange
Used to support the process of exchanging data
NameAliasesDescription
MessageHeaderThe header for a message exchange that is either requesting or responding to an action. The reference(s) that are the subject of the action as well as other information related to the action are typically transmitted in a bundle in which the MessageHeader resource instance is the first resource in the bundle.
OperationOutcomeA collection of error, warning or information messages that result from a system action.
Parameters(Not defined yet)
SubscriptionWebHook, HookThe subscription resource is used to define a push based subscription from a server to another system. Once a subscription is registered with the server, the server checks every resource that is created or updated, and if the resource matches the given criteria, it sends a message on the defined "channel" so that another system is able to take an appropriate action.

Terminology
The terminology sub-system
NameAliasesDescription
ValueSetA value set specifies a set of codes drawn from one or more code systems.
ConceptMapA statement of relationships from one set of concepts to one or more other concepts - either code systems or data elements, or classes in class models.
NamingSystemA curated namespace that issues unique symbols within that namespace for the identification of concepts, people, devices, etc. Represents a "System" used within the Identifier and Coding data types.

Content
Specifying allowable content
NameAliasesDescription
StructureDefinitionTemplateA definition of a FHIR structure. This resource is used to describe the underlying resources, data types defined in FHIR, and also for describing extensions, and constraints on resources and data types.
DataElementMaster Observation, Data ElementThe formal description of a single piece of information that can be gathered and reported.

Operations Control
Specifying the behavior of operational systems
NameAliasesDescription
ConformanceA conformance statement is a set of capabilities of a FHIR Server that may be used as a statement of actual server functionality or a statement of required or desired server implementation.
OperationDefinitionA formal computable definition of an operation (on the RESTful interface) or a named query (using the search interaction).
SearchParameterA search parameter that defines a named search item that can be used to search/filter on a resource.

Miscellaineous
Managing specification and testing
NameAliasesDescription
ImplementationGuideA set of rules or how FHIR is used to solve a particular problem. This resource is used to gather all the parts of an implementation guide into a logical whole, and to publish a computable definition of all the parts.
TestScriptTestScript is a resource that specifies a suite of tests against a FHIR server implementation to determine compliance against the FHIR specification.

Additional Resources will be added in the future. A list of hypothesized resources can be found on the HL7 wiki . Feel free to add any you think are missing or engage with one of the HL7 Work Groups to submit a proposal to define a resource of particular interest.
