Alpha HAT is here!


Following our issue of the HAT technical briefing paper and the pre-Alpha HAT in Oct 2015, we are now releasing the Alpha version of the HAT for testing by the community.

This Alpha release of the HAT is yet to contain all of the features that we have planned for the final version; this also means that it may still contain bugs and could crash. So we are counting on you, our early adopters and development community, to give us constructive feedback and help make the HAT better. But the good news is that this version will include a (very) basic version of our Hyperdata Browser for your HAT data.

So sign up for your Alpha HAT now!

If this is the first time that you’ve heard of the HAT, please visit our website where you can find more information including our vision and design of the HAT ecosystem via our briefing papers. In summary, the HAT consists of a database schema, a data logic layer and APIs within a trust framework that enables individuals to self-service (contain, transform, bundle and exchange all types of personal data) their personal data to reveal their contextualised insights and share the right information (quality and quantity) with the right people, in the right situations, for the right purposes, and to gain the benefits.

So what’s new in the Alpha HAT? In this Alpha release (Nov 2015) of the HAT, we have included:

The Alpha HAT is licensed under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. This means that you can use, copy and redistribute the Alpha HAT in any medium or format, as long as it is in its original form (without remix, transform, or build upon) and your work is not for commercial purposes. To view a copy of this license, visit

If you are interested in the commercial license of the HAT, it will soon be available as part of membership with the HAT ecosystem which will give HAT Platform Service Providers (HPPs) and HAT Application Providers (HAPs) the ability to interoperate globally and tap into HAT Data Exchange (HATDeX) services such as certification, compliance and aggregate metadata services (to show favourite bundles, collections etc.). Read this blogpost for more about the HATDeX.

If you simply just want a HAT and don’t want to get your hands dirty with too much tech muddling, you can sign up to receive a commercial HAT when this is launched. This will be available to individuals and organisations on a freemium basis, along with some initial applications provided by our HAT Platform Providers (HPPs), the first two of which are Enable iD in the UK and Europe, and Noggin Pte Ltd in Singapore.

If you are from the development community and want to gain a better understanding of the HAT-based personal data ecosystem and have a play with the HAT, please:


As part of the Alpha HAT release, we are making HAT available to 50 early adopters. However, to get your Alpha HAT, you will need to opt into the HARRIET research, which manages the Alpha HAT system. This means that your data is not private as the research team will need to test and make sure things are not broken etc. (this is the ALPHA version after all!) and therefore they will be able to see your data. If this makes you uncomfortable, so wait for the Beta version that will be launching globally in April! You can sign up here to be a Beta HAT user.

Please also note that we only have 50 HATs available at the moment, and we will combine your signup time and your digital activeness (calculated from the survey) to determine if you qualify to get the Alpha HAT.
