The Good Practice Guide aims to provide recommendations for the use of the EU metadata catalogue to  identify real-world data sources suitable for specific research questions and to assess the suitability of  data sources proposed to be used in a study protocol or referred to in a study report.

It also provides a detailed description of all the metadata elements as envisaged to be used in the EMA  catalogue, which have been published by HMA/EMA in the List of metadata for Real World Data Catalogues, and it guides the user for the insertion and maintenance of data in the catalogue.

The catalogue is targeted for release in late 2023.
