ISO 15926

PCA initiated ISO 15926 in 1997 and has chaired the group in ISO TC184/SC4 accountable for ISO 15926 ever since. The first four parts have been completed as ISO standards while the Parts 6 and 7 are still in progress.

A statement from the IT industry:

ISO 15926 is extraordinarily robust and complete, both in its specification and the technical infrastructure through which it is deployed. These characteristics differentiate ISO 15926 from other, less formal attempts at standards development. Other standards initiatives have broken down due to their inability to scale the submissions process, cover the structural requirements of multiple disciplines and provide an enterprise-grade technology foundation.

Reference Data Service (RDS)

PCA operates the RDS as a public service for the global process industry including oil and gas. RDS contains all reference data in ISO 15926, the Oil & Gas Ontology (OGO), reference data from EU projects in environment and pipelines, reference data for capital intensive project, as well as some reference data from defence and ship industries. The Norwegian Ministry of Defence, Det Norske Veritas (DNV) and Norwegian Oil Industry (OLF) have funded the development of The Reference Data System and is now funding the operation of the system.

Integrated Operations

The Norwegian Oil Industry (OLF) has defined IO as "real time data onshore from offshore fields and new integrated work processes". OLF has decided to use ISO 15926 as the instrument for integrating data across disciplines and business domains. This integration process requires an Oil & Gas Ontology (OGO). The OGO is stored in RDS and the Special Interest Groups (SIGs) continuously maintain, enhance and extend the ontologies within the different business domain in the EP value chain.

Semantic Days

Semantic Days is an annual conference that has become a meeting place for industrial use of semantic web technologies where also research institutions and universities make significant contributions.
