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.

PCA RDL (Reference Data Library) Content Access

IMPORTANT NOTE : Since 2011 the JORD Project is working to enhance the PCA RDS in partnership with FIATECH. For a general timeline of JORD project activities, see the project page. For access to RDL content via the latest RDS see below - latest first:

SPARQL Endpoints

The following SPARQL queryable triple-store endpoints are available:

JORD Endpoint V2 (Interim test & evaluation status, July 2012)

The human browser access & query page is

The actual SPARQL endpoint is

(NOTE : Documentation is in progress. Content and query functionality is the same as V1 below. V2 uses Fuseki upgrade from Joseki to support user Sandboxes with update queries and bulk upload, as well as improved memory performance. Current test & evaluation status endpoint address will switch over to persistent PCA RDS Endpoint address, when production status is declared. For new SANDBOX SERVICE REQUESTS - please use RDS Support Request Ticket - see below.)

JORD Endpoint V1 (Interim production supported status, September 2011)

The human browser access & query page is

The actual SPARQL endpoint is

(Documentation is here. As well as the PCA RDL, content includes pointers to RDS/WIP equivalent resources to maintain compatibility for iRINGTools and other users. A full list of available predicates is returned by this query.)

RDS/WIP Endpoint (Status - obsolescent with limited support)

The initial "RDL Facade dot Org" RDS/WIP Enpoint is

(For more information see the iRINGToolsUserGroup )

(PLEASE NOTE : Subject to satisfactory evaluation of the later endpoints above, the RDS/WIP Endpoint is due for retirement by September 2012. Please plan accordingly.)

PCA "Brutus" RDL Content Browser

Public access to the PCA RDL Content is available via a read-only guest log-in to the master Reference Data Editor of the PCA RDL. It is a thin client requiring Java Runtime Environment 1.4 or more. The client is also available for download:

(NOTE : These browser clients run on the legacy "Brutus" database, which currently remains the PCA RDL Master. JORD Endpoints above are populated with OWL file exports from here. When upgraded tools from the JORD Project are sufficiently complete, Brutus will cease to be the master and will be retired.)

File-Downloads of PCA RDL Content

The PCA RDL Content is also available for public access and/or download in different formats:

(NOTE : These are currently generated by export from the "Brutus" master above. The intention is to continue support for these or equivalent exports once the JORD enhanced RDS becomes the master RDL.)

RDS Operations Support

Registered users of the PCA Reference Data Services are also provided with operational support. These services are explained and accessed from RDS Operations Support Home.The purpose of these services is to ensure high quality and timely handling of requests made to or about the RDS (Reference Data Services) System and RDL (Reference Data Library) Content. Support arrangements are defined according to ITIL® and the ISO 20000 Specification.

Existing Support Users should create support ticket requests directly here.
(Note separate log-in required.)

Note that:

  • Registered Users who do not also have PCA Membership receive a reduced operational support service.
  • The PCA Operations Support Service operates the process of handling RDL Content Change Requests and clarifications in support of the RDL Maintenance Procedure, but does not operate the full content maintenance process.
  • Where such Change Requests include proposed new RDL Content please submit / attach using the Batch Upload Spreadsheet format. For explanation and a template of the spreadsheet format used to batch import reference data items, refer to the RDS Spreadsheet Batch Upload.
  • Where users require guidance on how to relate or map their business data using ISO 15926 Reference Data, please see joint PCA / FIATECH JORD Mapping Methodology (via the JORD project pages).
