JORD Project Commitment

A joint meeting of the boards of PCA and FIATECH in Houston on 25th Feb 2011 agreed that sufficient member commitment had been achieved to kick-off the implementation phase 1 of the Joint Operational Reference Data services enhancement project. Additional funding is necessary to complete the proposed scope, and there is still time for additional sponsors to sign up as charter members before a face-to-face project kick-off meeting currently being planned for early May in London. For project details and instructions see the JORD Project Prospectus.

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 defense and ship industries. The Norwegian Ministry of Defense, 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.

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.


The POSC Caesar Association website is powered on Trac using a wiki, the svn version control system a ticketing system, discussion forums and more making the website a powerful and efficient tool for collaboration.
