Summary0010460: 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.

Add a detailed description of UANodeSet comparisions with NamespacePublicationDate and ModelVersion.
