Euclid Mission Archive (EMA) plays a key role in the data processing in Euclid. The data-centric approach of the organization of the mission data processing makes EMA a beginning and end points for any operations with data, including processing, qualification, verification and publishing. EMA will not only keep the data but will be the distribution point of any software used in the mission, will contain data lineage, implement access policy. Effectively EMA will become a glue between SGS components.

The purpose of this workshop is to bring together developes and users of EMA, to shape the concept of the archive and, based on the responce from EMA users to start development and implementation of EMA. Euclid System Team will present current view on EMA and propose common tools and methods which will simplify development of Euclid data model and will involve OU in the process, OU should provide System Team with the OU's view on the data processing of OU-realted data.

The outcome of the workshop will be organization of Euclid Mission Archive User Group(s), input from OUs/SDCs to EMA Requirements and EMA Concept, adaptation of the data model developing framework within Euclid SGS.

The workshop will be based on the results achieved in Bolognia SGS kick-off meeting and will put a roadmap toward EMA for the next decade.


  1. explain role of EMA in Euclid data processing to OU/SWG community
  2. gather requirements from OUs/SWGs to EMA
  3. set up a framework for the communication between System Team and OUs/SWGss
  4. provide OUs with necessary information on data modeling inside Euclid

Amongst its other functions the EMA will form the interface for Euclid scientists to search for and and access Euclid data. Moreover, there are considerable advantages in having a prototype EMA available in the near future, so that it can support to distribution and management of OU-SIM and OU-EXT data. Although detailed requirements will eventually filter down from SWGs and OUs to the system, this will be a slow progress. As discussed in Bologna there are considerable advantages in providing a more direct mechanism to allow users (particularly scientist in the SWGs) a direct method of providing their requirements now.

Apart from the direct access to the data EMA will become a common ground for the collaboration in the developing of pipelines and workflows, verification and qualification of algorythms, dissemination of data processing software.



Goal: to give an overview of the current status of EMA and the role of EMA in SGS, propose a common approach to data modeling
