I only became aware of the W3C Open Government Community Group today.
A grassroots initiative named OParl is active in Germany with the aim to standardize the format of parliamentary data of councils of municipalities, city councils and other similar councils. The text on the website so far is only available in German, sorry, but the identifiers used in the specification are in English.
The initiative is already supported by the major German vendors of council information system software, several city administrations, IT-service providers and Open Data initiatives.
Last week an OParl-workshop decided to base the specification on the W3C standard JSON-LD. In other words: the intention is to create a specification for Linked Parliamentary Data.
One of the intentions of OParl is to extend the community of stakeholders and collaborators and the specification so that it can be used in other parts of the world. And at the same time state and national parliaments should also be able to use it to publish legislative data.
Looking forward to collaboration between OParl and the W3C Open Government Community Group !
