[ckan-dev] Resource view plugin for ZIP files

Thu Jul 9 15:58:13 UTC 2015

If the server hosting the file supports range requests this would be
quick even for large ZIP files. IIRC the index of files contained is
stored right at the end of the ZIP and that's all you need.

It might be better to have a plugin store the list of files as a
resource extra after the upload is complete to save the repeated work
for clients and allow indexing.
