DEXPI (Data EXchange in the Process Industry) is an initiative to provide a neutral data format to exchange process information between the many engineering tools used in the process industry.

A first goal was to define a data model for the exchange of P&IDs. The current specification is published on Github and ready and free for use.

DEXPI encourages software vendors to become members of the initiative and implement the data model into their tools. To support this DEXPI organizes so called Hackathons to speed up the development of import and export interfaces based on the DEXPI specification.

Pain points driving such an approach have been and still are:

  • currently no standard exchange format for process data (like e.g. STEP for 3D modeling)
  • exchange of P&ID data between systems of owner/operators and engineering contractors is needed to allow all players making use of their preferred tools
  • a process data model is needed during all phases of the plant lifecycle


  • founded 2011 by BASF, Bayer, Evonik
  • first version (1.0) of a process data model published in 2016
  • current version of the data model is 1.2
  • publishing of version 1.3 scheduled for autumn 2019
