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.

Libertas 24.1.3 brings a series of significant improvements and new features designed to enhance your experience. Here are the highlights of this release:

Libertas 23.2.2 introduces several key fixes and improvements aimed at enhancing the performance and stability of the platform. Here's a summary of the notable changes:

• Performance Improvements: The data-create endpoint for PostgreSQL now benefits from multi-value insert statements, resulting in significant speed enhancements, with observed import time reductions of up to 50% in test environments. Additionally, batch size configurations for both data-create and data-update endpoints have been introduced, providing flexibility and optimization options.
• Model Read and Data Update Fixes: The release resolves problems with model reading for non-super users and ensures correct behavior of the data-update endpoint when handling empty values.
• Database Connection Pooling: A production-ready database connection pool has been implemented to increase connection reuse and mitigate the risk of reaching maximum connection limits. Configuration options are available via Manatee settings.
• OSGi Shell for AReS: A new OSGi shell for AReS has been introduced under the 'ares' command, enabling management of Libertas connections and resources via CLI.
• Database Recovery and Session Timeout Configuration: Libertas runtimes now support automatic recovery after database restarts, minimizing service interruptions. Session timeout mechanisms can also be configured via 'config.xml' files.
• Enhanced MS SQL Server Support: Improved support for MS SQL Server includes better transaction and connection handling, handling of large parameter queries, and ensuring compatibility with MS SQL Server SQL dialect.
• Tagging Support: Libertas 23.2.2 introduces support for tagging via HTTP headers, facilitating integration with tools like Postman.
