23 participants from 9 companies in 4 countries meet to test ASAM ODS client applications, ASAM ODS servers, and ATFX files for compliance with the ASAM ODS standard.

As in previous cross-tests, the participating companies came together to test and improve their software in real-life scenarios. The participants helped each other to understand the small differences in the data formats of the various programs and to solve the difficulties that can arise when interpreting this data. They were also able to discuss ambiguities and contradictions in the standard documentation, which can then be eliminated in the next version of the standard.

Once all the servers in the network had been set up, the first client connections were established. At the end of the first day, all clients were able to connect to all servers.
Each participating client was assigned an Excel sheet with the scenarios to be tested for each server. This time, the participants agreed to test only the http interface of the ODS standard. The scenarios were, for example:

• Opening the session
• Reading context variables
• Browsing through the test hierarchy
• Reading the model including the n to m relations
• Simple and nested queries
• Reading attributes and mass data including size and unit references
• Writing new instances and mass data
• Handling of external files (AoFile)

The tests were then carried out on the second day. Groups were formed with at least one representative each from the client manufacturer and the server manufacturer. A few identified problems were posted directly as issues in the ASAM GitHub of the ASAM ODS working group to be resolved with the upcoming release.
