5 Star Linked Open Data ... in order to encourage people -- especially government data owners -- along the road to good linked data, I have developped this star rating system. Linked Open Data (LOD) is data id Linked Data which is released under an open licence, which does not impede its reuse for free. Creative Commons CC-BY is an example open licence, as is the UK's Open Government Licence. Linked Data does not of course in general have to be open -- there is a lot of important use fo lnked data internally, and for personal and group-wide data. However, if it is open government data then it does have to be open! Under the star scheme, you get one (big!) star if the information has been made public at all, even if it is a photo of a scan of a fax of a table -- if it has an open licence. The you get more stars as you make it progressively more powerful, easier for people to use.
