Microformat for Public Service feedback

Describe your idea:

It would be nice to have a single format which allows for data sharing and portability across platforms. Maybe a microformat is not the answer, but the idea is to have shareable and machine readable data, standardised across platforms.

What problem does it solve?:

There are many websites collecting and competing for feedback on Public Services. Citizens are confused between PatientOpinion and NHSChoices and publicexperience. The result is that less feedback is generated and less meaningful results are available. Data sharing across platform will allow for better insight and more feedback.

Type of idea: A piece of infrastructure or an API
