The Internet Archive allows members to upload collections using an Amazon S3 compatible API, and this can be used with git-annex's S3 support.
So, you can locally archive things with git-annex, define remotes that correspond to "items" at the Internet Archive, and use git-annex to upload your files to there. Of course, your use of the Internet Archive must comply with their terms of service.
A nice added feature is that whenever git-annex sends a file to the
Internet Archive, it records its url, the same as if you'd run git annex
addurl
. So any users who can clone your repository can download the files
from archive.org, without needing any login or password info.
The url to the content in the Internet Archive is also displayed by
git annex whereis
. This makes the Internet Archive a nice way to
publish the large files associated with a public git repository.
webapp setup
Just go to "Add Another Repository", pick "Internet Archive", and you're on your way.
basic setup
Sign up for an account, and get your access keys here: http://www.archive.org/account/s3.php
# export AWS_ACCESS_KEY_ID=blahblah
# export AWS_SECRET_ACCESS_KEY=xxxxxxx
Specify host=s3.us.archive.org
when doing initremote
to set up
a remote at the Archive. This will enable a special Internet Archive mode:
Encryption is not allowed; you are required to specify a bucket name
rather than having git-annex pick a random one; and you can optionally
specify x-archive-meta*
headers to add metadata as explained in their
documentation.
# git annex initremote archive-panama type=S3 \
host=s3.us.archive.org bucket=panama-canal-lock-blueprints \
x-archive-meta-mediatype=texts x-archive-meta-language=eng \
x-archive-meta-collection=test_collection \
x-archive-meta-title="original Panama Canal lock design blueprints"
initremote archive-panama (Internet Archive mode) ok
# git annex describe archive-panama "a man, a plan, a canal: panama"
describe archive-panama ok
The above uploads to the test collection where items are removed after thirty days. Uploads can persist by changing to another writable collection.
Then you can annex files and copy them to the remote as usual:
# git annex add photo1.jpeg --backend=SHA256E
add photo1.jpeg (checksum...) ok
# git annex copy photo1.jpeg --fast --to archive-panama
copy (to archive-panama...) ok
update lag
It may take a while for archive.org to make files publically visible after they've been uploaded.
While files can be removed from the Internet Archive, derived versions of some files may continued to be stored there for a while after the originals were removed.
exporting trees
By default, files stored in the Internet Archive will show up there named
by their git-annex key, not the original filename. If the filenames
are important, you can run git annex initremote
with an additional
parameter "exporttree=yes", and then use git-annex-export to publish
a tree of files to the Internet Archive.
Note that the Internet Archive may not support certian characters in filenames (see FAQ). If exporting a filename fails due to such limitations, you would need to rename it in your git annex repository in order to export it.
It doesn't seem like git annex addurl by itself supports the archive.org urls...
I also tried the "details" url (http://archive.org/details/Republica2012-EbenMoglen-FreedomOfThoughtRequiresFreeMedia) - but that just downloads the webpage, not the video either...
Even the ultimate video URL doesn't work:
... even though that URL actually gives out a proper 200 OK response code.
Any ideas? --anarcat
This was a misleading error message. The url you are trying to add to the file does not match the size recorded for the file already in the annex. (Or possibly the file's key has no recorded size). If you really want to add the url to the file despite it being a different encoding, you can use --relaxed, although fsck may not like the result if you ever end up downloading that url..
(Please file bug reports for problems in the future, rather than posting comments on only vaguely related pages which as we can see here can turn out to be entirely offtopic.)
