= Reference Data Services =
PCA provides services for Reference Data 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". Since the Reference Data Library (RDL) is extensible and managed, the content at any given time is often referred to as "WIP" or Work In Progress.

Access to the PCA Reference Data Library (RDL) is provided under the terms of the PCA Articles of Association, namely "Reference Data Libraries shall be open, i.e. they can be used by everyone for their own purpose, on equal terms."

Service Requests for RDS System Support and/or RDL Content Support are provided for registered users.

This page describes what those services are and how to access them.

'''Browser Access to [http://rds.posccaesar.com/apps/rdsclient108.html ISO 15926 POSC Caesar RDL] Content'''

  Public access to the PCA RDL Content is via a read-only guest log-in to the master [http://rds.posccaesar.com/apps/rdsclient108.html Reference Data Editor of the PCA RDL]. It is a thin client requiring [http://www.java.com/ Java] Runtime Environment 1.4 or more. The client is also available for download: http://rds.posccaesar.org/downloads/PCA-RDS_client.zip.

'''''IMPORTANT NOTE - 2011 Update''''' - PCA is collaborating with FIATECH on the [wiki:FiatechJord JORD (Joint Operational Reference Data)] initiative to enhance the PCA RDS. The services described on this page continue to be provided by PCA according to existing Service Level Agreements until such time as upgraded services are announced and supported. In the interim, in order to work-around deficiencies in both content and in the Browser tool user interface, it is recommended that users also check content available through the other on-line and downloadable formats noted below. If in doubt concerning the content, please use the [http://rdssupport.posccaesar.org/wiki/RdsServicesOffered Operations Support service requests] to log questions, issues and requirements. (Note ''separate ''PCA User Log-in required.)
