datacatalogs.org - one (data) catalogue to bind them all

I wrote in January about the problem of a proliferation of different sites with inventories of open data catalogues, each site with its own omissions and issues: open data - who shall catalogue the catalogues?

Via the open-government mailing list I learn there is now a comprehensive effort to unify this information on a single curated site:

for example, here's the entry for the City of Ottawa: http://datacatalogs.org/catalog/ottawa_ca
