DCAT-AP is a European specification of how to describe public sector datasets. Open Meal has one DCAT-AP file to describe the central parts of the specification (i.e. List Data Providers) and one per Data Provider to describe their implementation of Open Meal.
An example of a DCAT-AP file for Data Providers is available at dataprovider-dcat-ap-example.rdf
Please change all URLs, email addresses and mentions of Data Provider into the relevant information.
