We are happy to announce our MPEG-V Validator which is available here.
The validator offers the possibility to validate descriptions for MPEG-V Part 2 (CIM), 3 (SEM), 4 (VWOC), and 5 (IIM). This can either be done via file upload, URL or direct input of the description. Furthermore, the validator checks not only schema compliance but also semantic compliance of a description as specified in the corresponding parts of the standard.
Feel free to test the MPEG-V validator (examples are provided) and provide us with your feedback.
