Summary0010463: NamespacePublicationDate and ModelVersion are described differently than they are used ...
Description

As agreed in the weekly meeting on July 29, 2025, the description of the use of the “ModelVersion” property in the ‘NamespacePublicationDate’ property must be adapted to match how the OPC Foundation uses the “NamespacePublicationDate” property.

The description in 6.3.13 NamespaceMetadataType:

  • The NamespacePublicationDate Property provides the publication date of the namespace version. This Property value can be used by Clients to determine the latest version if different versions are provided by different Servers when the ModelVersion is not provided. If there is no formal publication date defined for the namespace this Property shall be set to a null DateTime.
TagsNo tags attached.

This info needs to be added to Part 6 as well to describe how Nodesets are compared. Part 5 should reference Part 6. Agreed to fix this in the 1.05.06 release (post RC).

We found a more detailled description in Part 6 'https://reference.opcfoundation.org/Core/Part6/v105/docs/F.2':

  • The version of the UANodeSet expressed as a string which conforms to the syntax defined in the SemVer specification. The comparison rules from the specification are used to determine which UANodeSet precedes another.
  • When the ModelVersion is specified in two UANodeSets, the PublicationDate is not used when comparing the UANodeSets.
  • When the ModelVersion is specified in only one UANodeSet, the PublicationDate is used when comparing the UANodeSets and the ModelVersion is ignored.
  • The ModelVersion is optional in previously released UANodeSets and it is required in all future UANodeSets.

It appears that all of the needed text is already in Part 6.

Changed ModelVersion definition to:

When comparing two UANodeSets the following rules apply:
When the ModelVersion is specified in both UANodeSets it is used for the comparison and if they are the same then the PublicationDate is used.
When the ModelVersion is specified in only one UANodeSet it is considered newer than the one without the ModelVersion. The PublicationDate is ignored.
When the ModelVersion is not specified in either UANodeSet the PublicationDate is used for comparison.
The ModelVersion is mandatory for all UANodeSets conforming to version 1.05.02 or later of this specification.
