Could you tell me what's the meaning of magic and vt_type?

magic: what libmagic (the library behind file) would return for that content type (or the closest approximation of that). This is used as part of "backward compatibility". Note that since there were too many discrepancies, we have removed backward compatibility in 0.6.0+ (and thus we have removed magic entries as well).

vt_type: just an annotation on what's type used by VirusTotal for a given content type. This metadata is only used as part of the training and not really from any client, and that has been removed as well.

Anyways, noted down in #834 that we shoud improve the documentation of these aspects.

Closing this one; feel free to re-open in case you have follow up questions. Thanks!

Thank you. And there are some content types' group seem to be null. Could you tell me the reason? The "avi" format in my opinion should be "video" group.

plus: Maybe this repository has some permission setting errors? I couldn't reopen this issue.

About group and other metadata: that json contains entries for many more content types that we actually support (and for many of them we don't / didn't have proper metadata), but we (should) have proper metadata for any supported by the model v1. That json is not really part of the API and should not be rely upon (and it has in fact been refactored in the new version).

About reopening issues: it turns out it's a "feature" from github, you can only reopen if you are a collaborator or if you closed the issue yourself (ref: https://github.com/orgs/community/discussions/41926#discussioncomment-6975082). I reopened it now, feel free to follow up or close it if all answers are clear.

Thanks!
