Replication Data

This Dataset contains replication data for the linked publication. The Data provided are structured in four groups

  1. CS_NodeSets
  2. Metrics_Generated.zip
  3. Manual_Evaluations
  4. Scripts

CS_NodeSets

A collection of Files describing OPC UA Companion Specifications. Downloaded from https://github.com/OPCFoundation/UA-Nodeset on 24.02.2026.

Metrics_Generated.zip

Excerpts from the CS_NodeSets files, that examine different countable traits of the Companion Specification Models. Eleven different files are generated for each NodeSet (excluding Opc.ISA95.NodeSet2.xml, Opc.Ua.AMLLibraries.NodeSet2.xml, Opc.Ua.AMLBaseTypes.NodeSet2.xml, Opc.Ua.AMLBaseTypes.NodeSet2.xml, Opc.Ua.MTConnect.NodeSet2.xml, Opc.Ua.MachineVision.AMCM.NodeSet2.xml, Opc.Ua.PNDRV.Nodeset2.xml and Opc.Ua.Pn.NodeSet2.xml due to processing errors).

  1. Attributes.csv Column headers: NodeId,Attribute,Value,Value (Secondary) Set evaluated: all Nodes Included if Attribute Value explicitly set; AccessLevel included if different values used in NodeSet File
  2. Categories.csv Column headers: Category,BrowseNames,NodeIds Set evaluated: all hierarcy root Nodes Included if category tag set
  3. Children.csv Column headers: BrowseName,Number of Children,Size of Subtree,Breadth of Subtree,Depth of Subtree,NS Aggregation Score Set evaluated: all hierarcy root Nodes Included if Node spans a hierarchy with References derived from “Aggregates”
  4. DIT.csv Column headers: NodeClass,Name,NodeId,tDIT,rDIT Set evaluated: all Type Nodes Included: always
  5. DataTypeAggregation.csv Column headers: BrowseName,Number of Aggregated DataTypes,Size of Subtree Set evaluated: all DataType Nodes of type Structure Included: always
  6. Includes.csv Column headers: Kind of inclusion, BrowseName, NodeId, foreign Namespace Set evaluated: all Nodes Included if inclusion found
  7. InstOutOfTypes.csv Column headers: NodeId,NodeClass,BrowseName,NSRoot Set evaluated: Objects, Variables and Methods that are not InstanceDeclarations Included if recursively evaluated “highest” Parent is Object, Method, Variable, View
  8. Instances.csv Column headers: Type BrowseName,Total Instance Occurrences,Prototypes, Final Set evaluated: all Nodes (to find Reference Uses and TypeDefinitions) Included: all Type nodes
  9. MethodArguments.csv Column headers: Parent,Method Name,NodeId,Inputs,Outputs,ModellingRule Set evaluated: all Methods Included if BrowseName of Method in Namespace
  10. NOC.csv Column headers: BrowseName,Namespace,NodeId,NOC Set evaluated: all Type Nodes and their parent Nodes Included if Node has Children/Subtypes (Inheritance)
  11. NodeCounts.csv Column headers: NodeClass, Node Count Set evaluated: all Nodes Included: always

Manual_Evaluations

Notes of manual analysis in the Companion Specifications as found via https://reference.opcfoundation.org/

  • AccessLevel.md
    • Spec - Name of the Specification
    • AccessLevel mentioned - manual analysis: is AccessLevel included in the Type Definition Tables?
    • AccessLevel in NodeSet - result from automated analysis: are there different AccessLevel Values mentioned in the XML? If “not in file” is mentioned: manual analysis with search for String “AccessLevel” in XML
  • CUs.md
    • Spec - Name of the Specification
    • No. of CUs in XML - result from automated analysis
    • No. of CUs in Text - manual Analysis of section with title “Conformance Units” or “Profiles and Conformance Units”
    • No. of CUs per Type in XML (Min/Max/Mean) - result from automated analysis
    • No. of CUs per Type in Text (Min/Max/Mean) - result from manual analysis using CUs mentioned at the type definition tables [not used in publication]
    • No. of types per CU in XML (Min/Max/Mean) - result from automated analysis
  • Description.md
    • Spec - Name of the Specification
    • Number of Nodes with Description - result from automated analysis
    • Number of Nodes total - result from automated analysis
    • Description in Document? (at all) - Manual analysis in Node Attribute Tables and Component Descriptions
  • EventNotifier.md
    • Spec - Name of the Specification
    • Number of EventNotifier - result from automated analysis
    • relevant to instance? - manual interpretation based on CS document
  • InstancesOutOfTypes.md
    • Spec - Name of the Specification
    • Number of [NodeClass] IOOT - result from automated analysis
    • Remarks - Notes on what the Instances likely are, manual analysis based on Result-CSV-Files and NodeSet XML, in case of entry points also CS document
  • MethodModellingRules.md Notes on the Methods with ModelingRule Mantatory Placeholder and None, based on XML and CS document
