[Girder-users] Versioning files / folders

[Zach Mullen]

Hi Andy,

I actually wrote a prototype plugin[1] that does pretty much exactly what
you described. Basically, when you upload the file, you just need to pass
an extra parameter that identifies its canonical name/path, and then it
auto-increments a version. The plugin contains a rudimentary view for
listing the revisions of an asset in reverse-chronological order.

Thanks,
