Customer Testimonials

I am writing to thank you for your efforts in helping us meet the Environment Agency’s Open Data target to publish at least 1500 datasets as Open Data by the end of June. I am happy to report that we smashed our target by publishing 1932 datasets as of 28 June.
In particular, I would like to thank you for being such a support for both the Environment Agency and the other Defra bodies throughout the Defra metadata project, which was crucial to Defra meeting its target.
