This is particularly true of its path from raw data to published data and reference metadata. The process model presented here is a generic model that can capture key information about these stages in both a textual way and also in a more formalised way by linking to specific identifiable objects, and by identifying software components that are used. 6 - 7 -== {{id name="_Toc371077"/}}12.2 Model – Inheritance and Relationship view == 8 - 9 -=== {{id name="_Toc371078"/}}12.2.1 Class Diagram === 10 - 11 -**Figure 43: Inheritance and Relationship class diagram of Process and Transitions** 12 - 13 -=== {{id name="_Toc371079"/}}12.2.2 Explanation of the Diagram === 14 - 15 -==== 12.2.2.1 Narrative ==== 16 - 17 -The Process is a set of hierarchical ProcessSteps. Each ProcessStep can take zero or more //IdentifiableArtefact//s as input and output. Each of the associations to the input and output //IdentifiableArtefact//s (ProcessArtefact) can be assigned a localID. 18 - 19 -The computation performed by a ProcessStep is optionally described by a Computation, which can identify the software used by the ProcessStep and can also be described in textual form (+description) in multiple language variants. The Transition describes the execution of ProcessSteps from +source ProcessStep to +target ProcessStep based on the outcome of a +condition that can be described in multiple language variants. 20 - 21 -==== 12.2.2.2 Definitions ==== 22 - 23 -|**Class**|**Feature**|**Description** 24 -|+Process|((( 25 -Inherits from 26 - 27 -//Maintainable// 28 -)))|A scheme which defines or documents the operations performed on data or metadata in order to validate data or metadata to derive new information according to a given set of rules. 29 -||+step|Associates the Process Steps. 30 -|ProcessStep|((( 31 -Inherits from 32 - 33 -//IdentifiableArtefact // 34 -)))|A specific operation, performed on data or metadata in order to validate or to derive new information according to a given set of rules. 35 -||+input|Association to the Process Artefact that identifies the objects which are input to the Process Step. 36 -||+output|Association to the Process Artefact that identifies the objects which are output from the Process Step. 37 -||+child|Association to child Processes that combine to form a part of this Process. 38 -||+computation|Association to one or more Computations. 39 -||+transition|Association to one or more Transitions. 40 -|Computation||Describes in textual form the computations involved in the process. 41 -||localId|Distinguishes between Computations in the same Process. 42 -||softwarePackage softwareLanguage softwareVersion|Information about the software that is used to perform the computation. 43 -||+description|Text describing or giving additional information about the computation.
