Re: Universal distributed open government data catalog?

Hi all, Antti, Cory,

On Feb 12th, there's a meet-up of the Dutch SemWeb community at the Free
Univ in Amsterdam, where we'll be discussing this as well. There's some talk
within Dutch gov to start a catalogue, and I told them it will be the
perfect reason to get the SemWeb people involved in this, because it
provides the type of volume and platfrom to link data.

Will keep you posted.

best,
Ton
