Notes
This tool is now considered stable although feedback is always welcome. Please report any bugs in this test suite by raising an issue in its GitHub repository where there is a copy of the JavaScript code and the PHP helper functions. You'll find a model linkset and a JSON schema for a linkset in the separate GitHub repositoty.
Please note that the test suite does not currently check support for compression. If you're interested in contributing to the development of the GS1-Conformant resolver standard, or any other GS1 standard, please consider joining our working groups. Details of how you can do this, for free, are on the main GS1 website.
Code last updated 2025-06-03: checks for "walking up the tree". Entailed some changes to the way the linkset is processed. Improved procedure for requesting the linkset.
