git-annex's [[metadata]] works best when files have a lot of useful
|
|
metadata attached to them.
|
|
|
|
To make git-annex automatically set the year and month when adding files,
|
|
run `git config annex.genmetadata true`.
|
|
|
|
A git commit hook can be set up to extract lots of metadata from files
|
|
like photos, mp3s, etc.
|
|
|
|
1. Install the `extract` utility, from <http://www.gnu.org/software/libextractor/>
|
|
`apt-get install extract`
|
|
2. Download [[pre-commit-annex]] and install it in your git-annex repository
|
|
as `.git/hooks/pre-commit-annex`.
|
|
Remember to make the script executable!
|
|
3. Run: `git config metadata.extract "artist album title camera_make video_dimensions"`
|
|
|
|
Now any fields you list in metadata.extract to will be extracted and
|
|
stored when files are committed.
|
|
|
|
To get a list of all possible fields, run: `extract -L | sed 's/ /_/g'`
|
|
|
|
By default, if a git-annex already has a metadata field for a file,
|
|
its value will not be overwritten with metadata taken from files.
|
|
To allow overwriting, run: `git config metadata.overwrite true`
