"The PROV data model, PROV-DM, a generic data model for provenance that allows domain and application specific representations of provenance to be translated into such a data model and interchanged between systems. Thus, heterogeneous systems can export their native provenance into such a core data model, and applications that need to make sense of provenance can then import it, process it, and reason over it. A key goal of PROV is the specification of a machine-processable data model for provenance. However, communicating provenance between humans is also important when teaching, illustrating, formalizing, and discussing provenance-related issues. With these two requirements in mind, this document introduces PROV-N, the PROV notation, a syntax designed to write instances of the PROV data model according to the following design principles: •Technology independence. PROV-N provides a simple syntax that can be mapped to several technologies. •Human readability. PROV-N follows a functional syntax style that is meant to be easily human-readable so it can be used in illustrative examples, such as those presented in the PROV documents suite. •Formality. PROV-N is defined through a formal grammar amenable to be used with parser generators."

4.2.12.null.2 W3cProvenanceActivityType

This code system http://hl7.org/fhir/w3c-provenance-activity-type defines the following codes:

Code	Display	Definition
Generation	wasGeneratedBy	The completion of production of a new entity by an activity. This entity did not exist before generation and becomes available for usage after this generation. Given that a generation is the completion of production of an entity, it is instantaneous.
Usage	used	the beginning of utilizing an entity by an activity. Before usage, the activity had not begun to utilize this entity and could not have been affected by the entity. (Note: This definition is formulated for a given usage; it is permitted for an activity to have used a same entity multiple times.) Given that a usage is the beginning of utilizing an entity, it is instantaneous.
Communication	wasInformedBy	The exchange of some unspecified entity by two activities, one activity using some entity generated by the other. A communication implies that activity a2 is dependent on another activity, a1, by way of some unspecified entity that is generated by a1 and used by a2.
Start	wasStartedBy	When an activity is deemed to have been started by an entity, known as trigger. The activity did not exist before its start. Any usage, generation, or invalidation involving an activity follows the activity's start. A start may refer to a trigger entity that set off the activity, or to an activity, known as starter, that generated the trigger. Given that a start is when an activity is deemed to have started, it is instantaneous.
End	wasEndedBy	When an activity is deemed to have been ended by an entity, known as trigger. The activity no longer exists after its end. Any usage, generation, or invalidation involving an activity precedes the activity's end. An end may refer to a trigger entity that terminated the activity, or to an activity, known as ender that generated the trigger.
Invalidation	wasInvalidatedBy	The start of the destruction, cessation, or expiry of an existing entity by an activity. The entity is no longer available for use (or further invalidation) after invalidation. Any generation or usage of an entity precedes its invalidation. Given that an invalidation is the start of destruction, cessation, or expiry, it is instantaneous.
Derivation	wasDerivedFrom	A transformation of an entity into another, an update of an entity resulting in a new one, or the construction of a new entity based on a pre-existing entity. For an entity to be transformed from, created from, or resulting from an update to another, there must be some underpinning activity or activities performing the necessary action(s) resulting in such a derivation. A derivation can be described at various levels of precision. In its simplest form, derivation relates two entities. Optionally, attributes can be added to represent further information about the derivation. If the derivation is the result of a single known activity, then this activity can also be optionally expressed. To provide a completely accurate description of the derivation, the generation and usage of the generated and used entities, respectively, can be provided, so as to make the derivation path, through usage, activity, and generation, explicit. Optional information such as activity, generation, and usage can be linked to derivations to aid analysis of provenance and to facilitate provenance-based reproducibility.
Revision	wasRevisionOf	A derivation for which the resulting entity is a revised version of some original. The implication here is that the resulting entity contains substantial content from the original. A revision relation is a kind of derivation relation from a revised entity to a preceding entity.
Quotation	wasQuotedFrom	The repeat of (some or all of) an entity, such as text or image, by someone who may or may not be its original author. A quotation relation is a kind of derivation relation, for which an entity was derived from a preceding entity by copying, or 'quoting', some or all of it.
Primary-Source	wasPrimarySourceOf	Refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic's study, without benefit from hindsight. Because of the directness of primary sources, they 'speak for themselves' in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated. It is also important to note that a given entity might be a primary source for one entity but not another. It is the reason why Primary Source is defined as a relation as opposed to a subtype of Entity.
Attribution	wasAttributedTo	Ascribing of an entity (object/document) to an agent.
Collection	isCollectionOf	An aggregating activity that results in composition of an entity, which provides a structure to some constituents that must themselves be entities. These constituents are said to be member of the collections.
