This page contains links to various tools and information resources for finding, using and defining Reference data classes and relationships according to the ISO 15926 standard "Industrial automation systems and integration—Integration of life-cycle data for process plants including oil and gas production facilities".

ISO 15926 Reference Data

POSC Caesar Reference Data Library (PCA RDL)

WIP Browser-Editor
Reference Data Work In Progress (WIP) for Engineering Users
ISO 15926 POSC Caesar RDS
This is the master Reference Data Editor of the PCA RDL. A read-only guest login is available to the public for browsing the library. It is a thin client requiring Java Runtime Environment 1.4 or more.
File downloads
The PCA RDL is available for download in different formats:

ISO 15926-4 Initial reference data

ISO 15926-4 defines an initial set of reference data. Follow the link for more information on the ISO 15926 standard and for resources on the ISO 15926-4 reference data. See ISO 15926-2 for information and resources on the ISO 15926 Data Model.

Other resources

The PCA RDL is also available through other interfaces. These resources are however initial versions and are subject to upgrade or termination in the near future.

This browser is made up of a set of XML pages, one XML file per reference data item, and provide a simple view of the a snapshot of the PCA RDL (Feb. 2008) for both humans by formatting and styling the XML file using XSLT and CSS, and for computers who can read the XML. This same technique is planned used for the RDS/WIP project. The current set of pages have no built-in searching capabilities and no index page, this is why INANIMATE PHYSICAL OBJECT is used as point of entry.
Reference Data Browser
This application has powerful searching abilities, but can thus be slow to search an has a quite complex user interface.
Reference Data Web Services list
These web services are very simplistic and return very little result per query forcing multiple queries to gather a useful set of data.
RDS/WIP project
This project will in the near future give new and powerful browsing capabilities in the PCA RDL. See project page for more information.

PCA RDL Maintenance procedure

POSC Caesar has described a maintenance procedure by which PCA shall maintain and update the PCA Reference Data Library.
