Become a member

The BDTA welcomes all organisations and individuals willing to work with current members towards the shared Vision and Mission according to our Guiding Principles.

 There are two types of BDTA members:


Full membership grants all membership benefits, including voting in the General Assembly. Paying Fees are adapted to the nature of each member.


Associate membership has a reduced fee and grants restricted access to membership benefits and rights, including access to the General Assembly without a vote.

If you’re interested in becoming a member of the BDTA, please contact us.

Founding Members

The initial BDTA membership emerges from the SPHERE Project Consortium. This fact reflects the commitment of these Founding Members to the shared vision and objectives.
