Richard, all
I've done my homework and added a voiD description of lingvoj.org
dataset at http://www.lingvoj.org/void
It's still minimal, but at least got stats. Links stuff to be added ASAP.
For those who might care, note that it links to a new FOAF profile at
http://www.lingvoj.org/foaf.rdf

The problem at hand is: How to get reasonably accurate and up-to-date
statistics about the LOD cloud?
I see three workable methods for this.
1. Compile the statistics from voiD descriptions published by
individual dataset maintainers. This is what Hugh proposes below.
Enabling this is one of the main reason why we created voiD. There has
to be better tools for creating voiD before this happens. The tools
could be, for example, manual entry forms that spit out voiD
(voiD-o-matic?), or analyzers that read a dump and spit out a skeleton
voiD file.
2. Hand-compile the statistics by watching public-lod, trawling
project home pages, emailing dataset maintainers, and fixing things
when dataset maintainers complain. This is how I created the original
LOD cloud diagram in Berlin, and after I left Berlin, Anja has done a
great job keeping it up to date despite its massive growth. We will
continue to update it on a best-effort basis for the foreseeable
future. A voiD version of the information underlying the diagram is in
the pipeline. Others can do as we did.
3. Anyone who has a copy of a big part of the cloud (e.g. OpenLink and
we at Sindice) can potentially calculate the statistics. This is
non-trivial because we just have triples, and we need to
reverse-engineer datasets and linksets from them, it involves
computation over quite serious amounts of data, and in the end you
still won't have good labels or homepages for the datasets. While this
approach is possible, it seems to me that there are better uses of
engineering and research resources.
There is a fourth process that, IMO, does NOT work:
4. Send an email to public-lod asking "Everyone please enter your
dataset in this wikipage/GoogleSpreadsheet/fancyAppOfTheWeek."
Best,
Richard
