Semantic Days 2010

Semantic Days in Stavanger is an annual conference that has become a meeting place for industrial and public sector use of semantic technologies with solid contribution from research institutes and universities. Semantic Days 2010 will be held May 31 - June 2 in Stavanger, Norway. More information including news bulletins, preliminary program can be found here. Registration can be done here.

Americas PCA Forum and Member Meeting

The next PCA Forum and Member Meeting will be held in Houston March 4th, 2010 at Bechtel Tower, 3000 Post Oak Boulevard. The meeting is hosted by Bechtel. The PCA Forum will feature presentations and discussion focused on ISO 15926 with contributions like Owner/Operator and EPC key note, PCA’s vision for ISO 15926, information management, software supplier perspective and ISO 15926 usage and implementation. More information including preliminary program and registration are found here.

Moscow Rosatom Data Integration Tutorial

Rosatom Data Integration Tutorial was held in Moscow 4-5 of February 2010. It was attended by 286 IT-specialists, engineers and managers of Rosatom (Russian nuclear industry government holding corporation), INCOSE Russian chapter, representatives of other industries (e.g.Rus Hydro).

Speakers were Neill Pawsey for FIATECH, Ian Glendinning for POSC Caesar Association, Russell Adams for EPRI, Xavier Bazy for Strategy (Systems Engineering) in Dassault Systemes. It was a fascinating event with great presentations and demonstrations. Thanks to all of you that made this event possible!

Probably will ISO 15926 in Russia be adopted in nuclear industry and beyond: there was management buy-in. In addition to the main tutorial presentations, there were several management and technical workshops, where the high level of interest and commitment was also very much in evidence. The pressure is on to get the ISO15926 usage methodologies and content consistent in the publicly supported RDL.

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

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.
