PCA is the initiator of ISO 15926 "Integration of life-cycle data for process plants including oil and gas production facilities" and is committed to its maintenance and enhancement.

[3][4][5][6][7] The original focus was on standardizing technical data definitions for capital intensive projects at the handover from the EPC contractor to the owner/operators of onshore and offshore oil and gas production facilities.

The program was sponsored by The Research Council of Norway, two EPC contractors (Aker Maritime and Kværner), three owners/operators (Norsk Hydro, Saga Petroleum and Statoil) and DNV as service provider and project owner.

[9][10] POSC Caesar Association has with its current 36 members[11] from around the world and has established an international footprint (with a strong membership in Norway) that includes a variety of backgrounds, from academia and solution providers to engineering contractors and owners/operators.

ISO 15926 is therefore sometimes nicknamed the "Oil and Gas Ontology",[15] for some considered to be an essential prerequisite together with Semantic Web technologies[16] to get to better interoperability, an optimal use of all available data across boundaries and an increase in efficiency.
