This repo isn't software code, so code checks are limited.
Caution
Caution: no human commits in a year, and most questions go unanswered.
Why
- No human commits since July 2023, and only 0 of 8 recent issues got a maintainer reply. The repository holds mostly documentation, data or model files, so inactivity matters less than for a code library. (source 1, source 2, source 3, source 4)
- One person wrote 90% of human commits in the last year, and no human has committed in the last 90 days. The repository holds mostly documentation, data or model files, so inactivity matters less than for a code library. (source 1, source 2)
- GitHub found no license file, so the content is not clearly licensed for reuse. (source 1)
What would change this
- A release or merged commit from a maintainer, or replies to recent issues.
- A human commit in the last 90 days, or a second person taking a large share of commits.
- A license file is added.
