Hi,
I think this should be done in the overall context of XSCE as proposed
by David Farning. I think of what I am doing as a system and not as
isolated pieces. The ds-backup is independent because it only addresses
backup and restore of the Journal. However, this is going to become more
a system element as deployments turn to the shared model. It may become
moot, if the community abandons dependence on Sugar.

Hi Tony,
When you sent me your ds-backup script to migrate student datastore to
the server based upon the "favorite" star in the journal, I downloaded
the olpc repo, and added your version as a branch, and uploaded it to
https://github.com/georgejhunt/ds-backup/blob/ds_on_xs/client/ds-backup.py.
This is a branch which I called "ds_on_xs", but which could just as
easily be called "tony's ds-backup".
If you are interested, I'd like to create a repo at github for any of
the following: (can't do everything at once):
* epath library system,
* english language content,
* schools, a django application to keep track of students and teachers
And then we can all have access to it and make changes to separate
branches, and contribute to one another's code. If you'd like, you
can have your own github account (they're free), or I can give you shared
access to the repo that we create together at the
github.com/georgejhunt <http://github.com/georgejhunt> account.

Are these open source projects? Can you send links to project
code so
we can learn from the approach or include it directly
in XS? The plugin structure enables us to run multiple libraries.
Django is open source. I have sent you copies of the scripts with
install Django. Django is organized by applications - it provides
a framework to build an application.
The basic application is called schoolsite (this is sort of a
master application that handles the interface to Apache and to the
other applications). The library is handled by the 'library'
application.
Essentially the library content is organized into collections. A
collection is a set of media files (library items), a folder of
thumbnails (e.g. the first page of a pdf), and a json file
(books.json). The json file provides title, author, path to the
item, and mime-type, and path to the thumbnail. A script in the
library application loads the collection (i.e. puts the books.json
information in the database). The library is accessed by urls
(e.g. http://schoolserver/library/ for the home page). Clicking on
a category in the home pages goes to a topic page. A button on the
topic page goes to a list of items (show 9 per screen). A click on
the item, downloads it to the XO and installs it (activity) or
puts it in the Journal (pdf, etc.).
Logically, the library includes the Wikipedia (Wiki4Schools)
although that is not a Django application. It also includes
Wiktionary which is based on Mediawiki (and currently not working
because of the switch to PostgreSQL from MySQL). The Django
content consists of the Sugar Activities from ASLO, the English
pdfs from E-Pustakalaya, and a large collection of Old-time Radio
and Classical music (Musopen) audio files.
I am not sure about the comment about plugins. The current model
is to install XS-0.7 to obtain a running server (with the two
configuration scripts which should be eliminated), a
deployment-specific xs-custom script (which installs the usbmount
script, for example). The content is installed from a hard drive
using the usbmount script from the booted server.
My sense is that the deployment really needs to determine what
content it wants on the server particularly since the available
content is approaching a terabyte. We need software (api,
application) to enable this to be done, but the process will need
content specialists more than software engineers.
I can supply you with scripts and some rudimentary documentation
at the Django level and a sketchy index of what is in the content,
if that helps. It is very similar to Pathagar except that Pathagar
seems to intermediate between the internet and the server where
this application mediates between the servers and the XO clients.
