The purpose of the 'prov' LDD is to provide a PDS4 'Discipline_Area' insert for capturing provenance information. The 'prov' LDD is an implementation of the W3C PROV Data Model (PROV-DM). Provenance refers to information about the entities, activities, and people involved in producing a piece of data or artifact. Such information can be used to evaluate its quality, reliability, and trustworthiness. PROV-DM is the conceptual data model that underpins the W3C PROV family of specifications. The LDD is designed to support the creation of classes for specific types of PDS provenance. 1) SupersededLID - This class establishes a relationship between two LIDs, identifying one as having been superseded by another. It is an exposed class intended for use as an insert into the 'Discipline_Area' of a PDS4 label. An activity association is an assignment of responsibility to an agent for an activity, indicating that the agent had a role in the activity. It further allows for a plan to be specified, which is the plan intended by the agent to achieve some goals in the context of this activity. An activity is something that occurs over a period of time and acts upon or with entities; it may include consuming, processing, transforming, modifying, relocating, using, or generating entities.. The Affiliation class describes An agent is something that bears some form of responsibility for an activity taking place, for the existence of an entity, or for another agent's activity. Attributes: an OPTIONAL set (attrs) of attribute-value pairs representing additional information about this attribution. An entity is a physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary. The External_Reference class describes The Organization class describes The Person class describes This Provenance class is an implementation of the WC3 Provenance Model pattern .... The Provenance Activities class contains the Activity definitions. The Provenance Agents class contains the Agent definitions. The Provenance Entities class contains the Entity definitions. The Provenance Agents class contains the Agent definitions. The Relation Type class contains the set of relation types of which only one is allowed for each relationship. The Relationship class defines a relationship. The Software class describes ... The Superseded LID LDD relates two LIDs, one that supersedes the other. Usage is 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.) An activity association is an assignment of responsibility to an agent for an activity, indicating that the agent had a role in the activity. It further allows for a plan to be specified, which is the plan intended by the agent to achieve some goals in the context of this activity. Attribution is the ascribing of an entity to an agent. A derivation is 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. Generation is 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. An activity association is an assignment of responsibility to an agent for an activity, indicating that the agent had a role in the activity. It further allows for a plan to be specified, which is the plan intended by the agent to achieve some goals in the context of this activity.

This section contains the simpleTypes that provide more constraints than those at the base data type level. The simpleTypes defined here build on the base data types. This is another component of the common dictionary and therefore falls within the common namespace. activity1: an identifier (a) for the activity - The attribute activity1 is an OPTIONAL identifier for an activity. activity2: an identifier (a) for the activity - The attribute activity2 is an OPTIONAL identifier for an activity. agent1: the identifier (ag) of the agent whom the entity is ascribed to, and therefore bears some responsibility for its existence; The attribute agent1 is an OPTIONAL identifier for an agent. agent2: the identifier (ag) of the agent whom the entity is ascribed to, and therefore bears some responsibility for its existence; The attribute agent2 is an OPTIONAL identifier for an agent. attribute: the attribute component of an OPTIONAL set (attrs) of attribute-value pairs representing additional information about this attribution. The attribute description provides entity1: an entity identifier (e) -- The attribute entity1 is an OPTIONAL identifier for an entity. The attribute family_name. generatedEntity: the identifier (e2) of the entity generated by the derivation The attribute given_name. The attribute local_identifier provides The attribute name. The attribute orcid. The attribute rorid. time: an OPTIONAL "usage time" (t), the time at which the entity started to be used The attribute title provides usedEntity: the identifier (e1) of the entity used by the derivation value: the value component of an OPTIONAL set (attrs) of attribute-value pairs representing additional information about this attribution.
