To provide an example of a well-formed connector using our Unified Data Model (UDM) and the modern Xill Project Convention, we provide a zip-file with a complete Drupal 7 export connector. It supports Export of articles and documents (files) into UDM.
This connector has to be used in a certain folder structure to promote reusability and to prevent code duplication. This structure is defined in the Xill Project Convention. It needs the libraries lib.decorators, lib.mapper and lib.util to work. To show you an example of how this might look, we provide an example project here called demo_drupal_aem. Please note that the aem part of that project is currently just a dummy and does not adhere to the project convention.
