A brand new version of the CalaisModel Abstraction Layer has just been released. The Abstraction Layer provides a client API that maps RDF/XML entities to Java objects. The package includes the CalaisModelCreator, a tool used to automatically generate an instance of the CalaisModel, populated with your data. This instance of the CalaisModel enables reading the output RDF without writing any logic to process XML elements and without any specific knowledge of the underlying data structure.
The Abstraction Layer package currently includes Java and .NET libraries. A Python library will be released soon.
The Abstraction Layer can be used with all versions of Open Calais.
You can also get the Abstraction Layer files and documentation from the API page of the Open Calais website.
