Setting up digital media masters
Digitally stored media master files
are often relatively large,
and are more likely used as-is than edited.
We use git-annex to track such files.
As an addon to git,
some of the interaction is done through git commands,
while some is done using git-annex-specific commands.
Paths
You are recommended to use path suffix "annex"
for media master projects.
Examples:
- ~/public_annex/home-videos
- ~/private_annex/friends-snoring
- ~/shared_annex_family/xmas_photos
Create
To turn a folder into a git repository
(see also alternative of (cloning)[#Clone] an existing project),
go into the folder,
and initialize its git and git-annex databases:
git init
git annex init
To use git-annex only for large files (git for smaller ones),
add e.g. the following to file .gitattributes:
* annex.largefiles=((largerthan=100kb)and(not(mimetype=text/*)))
*.svg annex.largefiles=nothing
Finally, save all content:
git annex add .
git commit -m "Initial commit"
(final git commit is implied by a later git annex sync or git annex move)
Clone
To collaborate on a shared git repository,
create a local clone from the shared location,
and tell git-annex to use it:
git clone git://[[!template id=githost]]/example
git annex init
Publish
To publish a git repository initially created locally,
first create a new empty git and git annex publicly,
then tell your local git where its new origin will be,
and finally push your local git and git annex into its new public location:
ssh [[!template id=githost]] git init --bare --shared /srv/git/[[!template id=githost]]/example.git
ssh [[!template id=githost]] GIT_DIR=/srv/git/[[!template id=githost]]/example.git git annex init
git remote add origin [[!template id=githost]]:/srv/git/[[!template id=githost]]/example.git
git push --set-upstream origin master
git annex sync --content --all
