--------------------------------------------

Thanks Scott!

Indeed I've been doing too much PHP and javascript lately. I'll change that.

The space-separated metadata is fine because I'm URL-encoding all the string properties. I kept " " as the standard separator because it is already used in other parts of Hadoop Archives.

Using URL-encoding of strings makes it safe.

> Files inside hadoop archives don't keep their original:
> - modification time
> - access time
> - permission
> - owner
> - group
> all such properties are currently taken from the file storing the archive index, and not the stored files. This doesn't look very correct.
> There should be possible to preserve the original properties of the stored files.
