Background
There are many data sources available or desired. These data sources are stored on various media, ranging from an Excel file to a database. The format in which the data is stored often differs even though it concerns the same type of objects. Information models are often available, in various levels of completeness and each organization decides how to implement and expose these models to the outside world.
With the Objecttypes an attempt is made to go beyond an information model and create a standard on a message exchange level, in the form of JSON schema.
Various data sources
There are many existing data sources that could potentially be converted to an objecttype definition.
