opendata.hu has just launched last week. It is a community driven data hub, that aims to catalogue open datasets related to Hungary. Precognox provides the technical background to run the data hub while K-Monitor is operating and coordinating the community.
opendata.hu is an instance of CKAN – the world leading open source data catalouging software that has been used by international organization (e.g. http://publicdata.eu/), national and local governments (e.g. http://data.gov.uk/) and community driven open data portals (e.g. http://open-data.okfn.gr/). We do hope that open data brings benefits to business, society and government.
