During the course of the study the 6 use cases that were originally selected have been documented using DDI and uploaded to a local instance of the NADA catalogue service that is inaccessible to anonymous user access, hosted on an internal network in UCL. A public catalogue is available at https://epilanepilab.ich.ucl.ac.uk/nada within which 3 of these studies have been made available. In practice, the release of study metadata has proved problematic in some cases due to contractual constraints imposed when using third-party datasets and intellectual property concerns form principal investigators where the study design has not yet been published. We see value in provision of a limited, high-level metadata record, encoded in DDI where the variable level information is optional.
