How to express interest?  

The first step is to add an entry for your data source(s) on the HMA-EMA Catalogue of Real-World Data (RWD) sources.

Required steps:

1. Go to https://catalogues.ema.europa.eu/catalogue-rwd-sources and click on the ‘Login’ button (in the top-right hand side of the header).
2. You will be directed to the EU Login webpage. On this page, choose the 'Create an account' option. After providing your personal information (First name, Last name and Email), you will receive an email with instructions to activate your account. For more guidance on how to log in to the RWD Catalogues, please refer to the Support section of the Catalogues website.
   Note: If you already have an EU Login, you can login to the RWD Catalogues with those credentials.
3. Go to ‘My dashboard’ > ‘Add content’ > ‘+ Data Source’ and fill out the webform page. When you have uploaded the desired information, click on ‘Save’. When finalised, submit the Data Source entry by changing the state of the entry from ‘Draft’ to ‘Submitted’. In case of multiple data sources, you need to submit separate entries for each data source, one at a time.
   Note: This document contains all question fields included in the webform page for offline review (if needed).
4. Go to ‘My dashboard’ and click on the title of the Data Source entry that you have just submitted (the moderation state of the entry should be ‘Submitted’). Once you enter the Data Source entry page, click on the ‘Download as PDF’ button (in the light blue title banner of the entry). Also, make a note of the link appearing in the PURI field in your entry (see ‘Administrative details’ section).

In case you have submitted multiple Data Source entries, repeat the same process to download a PDF file and get the PURI information for each entry.

Once the entry has been submitted, please send an email to This email address is being protected from spambots. You need JavaScript enabled to view it. and copy This email address is being protected from spambots. You need JavaScript enabled to view it. in the email communication. The email should contain the pdf document(s) of the Data Source(s), the PURI link(s) to your HMA-EMA Catalogue entry (or entries) and a one-paragraph motivation for joining DARWIN EU® as a data partner. This email with attachments is considered as your Expression of Interest (EoI).
