The goal of the Joint PCA/MIMOSA Information Technology Architecture Special Interest Group is to develop an IT/IM/IS architecture which demonstrates the practical use of ISO 15926 and OpenO&M standards and that can be readily implemented by owner/operators as the basis for their own enterprise architectures.
See the PCA SIG page for further details.

The SIG published its first outcome - the PCA-MIMOSA Reference Architecture Framework for Integrated Engineering and Operations - in November 2013. It describes a reference architecture for defining, designing and classifying IT applications, systems and infrastructure in the upstream oil and gas industry, downstream petrochemical industry, and for engineering, procurement and construction projects.
