ISO 15926 – Integration of Lifecycle data
Matthew West
Shell International
ISOTC184/SC4 ISO 15926
• Rigorous 4D ontology– Physical objects extended in
time as well as space
• A full ISO standard (2003)• Developed as a data model• Also available in OWL Full• 201 entities in upper ontology, • Some 50,000 entities available
in process engineering ontology• Limited axiomatisation• Significant industrial support
from Oil and Process industries• 15 years of development
• Good for– Integrating diverse
information systems– Engineering applications– Applications involving time
and space– Managing change– integrating/analyzing mid
level ontologies

The upper ontologies present
here
Vast bulk of information systemsOntology limited or
implicit
Small number of sophisticated applications Small but increasing
number of lower and mid level ontologies
Huge potential to apply ontologies to traditional systems

ISOTC184/SC4 Shell Downstream Data Model
Identifies the key objects of interest to the business and the relationships between them
Identifies the underlying transactions and relationships
Provides an integrated specification of the information requirements for the Downstream Business (independent of any systems)Enables checking that the process model includes the processes for managing both objects and data about objects identifiedEnables checking that the physical data model, user and System interfaces in applications, support the information requirements
Contributes to design of future systems
Provides a basis for talking to application vendors about our
information requirements
The basis for Management Information
The basis for working with industry standards bodies
