Measure the complexity of your TTML files

Measure the complexity of your TTML files and help publish a standard.

The W3C is asking the community to run their IMSC/SMPTE-TT/EBU-TT content libraries through the validator at https://hrm.sandflow.com/ and report the results at https://github.com/w3c/imsc-hrm/issues or public-tt@w3.org.

The objective of the tests above is to make sure both the specification and the validator are correct, before the specification is finalized. More details at https://www.w3.org/wiki/TimedText/IMSC-HRM-1ED-Implementation-Report

The IMSC HRM is designed to measure the complexity of SMPTE-TT/IMSC/EBU-TT documents such that an author can ensure they will render correctly on client devices.

Looking forward to your results and feedback!
