Just a quick update on this.

FYI, the projects index was too big for PHP/Apache, but I've now fixed
the code to produce "paged" documents.

Accessing https://alioth.debian.org/projects/, requesting RDF, will
redirect to the first document /projects/?page=1, wich in turn contains
a pointer to /projects/?page=2, etc.

For the curious, this paging mechanism tends to implement parts of the
W3C LDP specs [3] (draft state).

You can test it with, for instance :
 $ curl -v -k -L -H "Accept: text/turtle" https://alioth.debian.org/projects/ 2>&1 | less

Now, I'll write a project catalogue harvester and see what you guys are
doing, that the NSA hasn't collected yet ;)

Any comments/questions welcome.
