OPC UA XSD schema

Hello,

Browsing the foundation ressources, we have found several XSD schemas defining the address space structure.

We have two questions:

1/ Is there a standard or a reference for this XSD schema ? In this case, which one is it ?

2/ We think some constraints in these schemas can be increased. Can we suggest some improvements to the foundation ?

Regards,

The schema is specified in OPC UA Part 6 (Annex F). The released schema is on the OPC Website.

For version 1.03 it is here: https://opcfoundation.org/UA/s…..odeSet.xsd

As for all OPC UA topics, suggestions (or errors) for this schema can be reported using Mantis as described here: https://opcfoundation.org/reso…..-tracking/. There are several projects – the one you want to report to is called “WSDL, XSD, XML Files”.

Thanks for your answer.

This file doesn’t seem to contain a revision number.

How can we be sure that the file did not change since 1.03? Is there a checksum or a revision attached to this file to be sure it is the same file?

The schema files are now tracked in GitHub:
https://github.com/OPCFoundati……Types.xsd

The source control version tracking gives you better information than a version could provide.
Note that the XSD is automatically generated.
