A Library is included in PPMN to provide standard instances that should be implemented by tools supporting PPMN . Currently, PPMN defines the instances for AcquisitionKinds , ClaimKinds , CustodyStartKinds , CustodyEndKinds , Ownership EndKinds , PedigreeEndKinds , and RelationshipKinds (See following sections). A kind of PPMNVocabulary that includes terms that specify the kind of relationship between two PPMN elements. Composition indicates that the element is composed of, in part, the element. Other elements could be included in this composition. Containment indicates that the element is a container for the element. indicates that the element is correlated with the element. This is often used when a mapping is required between the structures of two data elements. Dependency indicates that element is dependent in some way on the element. Miscellaneous indicates thatelement has some relationship with the target element that is of a kind that is not expressed through the other instances. Reference element references the element. Generalization indicates that the element is a generalization of the element (which is based on and extends the ). Transition indicates that "flow" or sequencing moves from the source element to the target element. An vocabulary of terms that specify the kind of CustodyOccurrence that results in the end of a ChainOfCustody . An instance that specifies that an entity was delivered to some other Party . An instance that specifies that an entity was transferred to some other Party . An instance that specifies that an entity was lost. An instance that specifies that an entity was destroyed. An instance that specifies that custody of an entity was relinquished in some other way. A vocabulary of terms that specify the kind of CustodyOccurrence that results in the start of a ChainOfCustody . An instance that indicates that a Party gains custody of an entity through some type of acquisition. An instance that indicates that a Party gains custody of an entity when the entity is found. An instance that indicates that a Party gains custody of an entity by creation of the entity. An instance that indicates that a Party gains custody of an entity by some other event. A vocabulary of terms that specify how the ChainOfOwnership was ended. An instance that specifies that an entity was sold to some other Party . An instance that specifies that an entity was bequeathed to some other party. An instance that specifies that an entity was gifted to some other Party . An instance that specifies that an entity died. An instance that specifies that an entity was lost. An instance that specifies that ownership of an entity was transferred to some other Party . An vocabulary of terms that specify the kinds of claims may be made . A foundational assertion that is held as true. A basic assertion. An assertion that is used in a logical argument. An assertion that is assumed to be true at the start of a process. An assertion that is assumed to be true at the end of a process. An assertion that indicates some degree of truth. An assertion that is based on other assertions. Enabler indicates that the source Occurrence uses the target Entity in some way that enables the Occurrence. However, the Entity is not used or become a part of any of the products or by-products of the Occurrence. Input indicates that the target Entity is an input to the source Occurrence is an input during the course of the Occurrence . Product indicates that the source Occurrence produces or creates the target Entity during the course of the Occurrence . Output indicates that the target Entity is an output of some kind of the Occurrence. . Waste indicates that the source Occurrence produces or creates the target Entity as waste during the course of the Occurrence . By-product indicates that the source Occurrence produces or creates the target Entity as a by-product during the course of the Occurrence . A vocabulary of terms that specify the kind of derivation that exists between two Entities . DerivedFrom indicates that source EntityTypes are derived in some way from target EntityTypes . QuotedFrom indicates that source EntityTypes are quoted from target EntityTypes . RevisionOf indicates that source EntityTypes are revisions of target EntityTypes . SouredFrom indicates that source EntityTypes are sourced from from target EntityTypes which in turn are produced by some party potentially with some special experience or knowledge . DescendantOf indicates that source EntityTypes are descendant in some way from target EntityTypes .
