<div dir="ltr">Hi Matthias, <div><br></div><div>Thanks for the feedback. Unfortunately raw URL is only provided for a single file, not a directory. As one repository could have many collections (collection is a directory containing resources), with git protocol, there are 2 ways downloading a single collection from a repository: git sparse checkout and git archive. Sparse checkout is not supported in Dulwich nor in Pygit2 (a Python wrapper using libgit2). And with the 2nd option, Github doesn't allow git archive.</div><div><br></div><div>One other alternative (which I am exploring now) is to clone a repository the first time user downloads a collection from that repository, and next time user downloads other collections from that repository, we just need to update and pull that repository. This is more efficient compared to downloading the whole repository (using zip url) every time user wants to download a collection.</div><div><br></div><div>We came to the decision that one repository could have many collections in the first place as it doesn't make sense (we thought) for users to create one repository only for one collection.</div><div><br></div><div>Cheers</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Jun 26, 2016 at 7:50 PM, Matthias Kuhn <span dir="ltr"><<a href="mailto:matthias@opengis.ch" target="_blank">matthias@opengis.ch</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Akbar,<br>
<br>
thanks a lot for the update, I especially liked the video, this makes it<br>
a lot easier for the audience (at least me :) ) to get an impression of<br>
the status quo. Good job so far!<br>
<br>
Concerning dulwich, did you checkout the #dulwich IRC channel and the<br>
mailing list which are mentioned in the project's readme [1] ?<br>
<br>
What exactly are the efficiency problems you are referring to? Maybe<br>
it's also worth looking into downloading individual files over http<br>
instead of the whole .zip file (<a href="http://raw.githubusercontent.com" rel="noreferrer" target="_blank">raw.githubusercontent.com</a>), that also<br>
allows doing partial downloads if you don't need a complete repository<br>
and you know which files you want.<br>
<br>
Looking forward to hearing more of this project, keep up the good work!<br>
<br>
Matthias<br>
