T. Berners-Lee talks about Open Data and his rating system

This is not something new, T. Berners-Lee has been talking about it since 2006, but I wanted to put some description of his 5-star system for Open Linked Data. You can read his entire idea from his post.

In it, Berners-Lee introduced the idea of providing stars for the data people publish and below you can see the types of levels1:

no star Web data Web data without an open license
one star open Web data make your stuff available on the web (whatever format) under an open license
two star open Web data make it available as structured data (e.g. excel instead of image scan of a table)
three star open Web data non-proprietary format (e.g. csv instead of excel)
four star open Web data use URLs to identify things, so that people can point at your stuff and serve RDF from it
five star open Web data link your data to other people’s data to provide context

He talked about his star system in 2010 in a gov2.0 expo in Washington, DC and you can watch the video from the talk:

All those efforts are important mostly to create context around various types of data being publishing continuously and the effort to create/establish relationships among them for the ability to discover related information which can be used in unexpected ways, adding value to it.

  1. The description and the badges were taken from http://lab.linkeddata.deri.ie/2010/lod-badges/ where you can get the badge which is more suitable for your data.
