Abstract
Our presentation will describe how requirements management in capital industries
can benefit from ontology-based methods. Our use case is the READI Joint
Industry Project in digitalised requirements for the Norwegian Continental
Shelf (offshore Oil and Gas). We propose a new kind of service, integrating
industrial ontologies with the templates needed to use them correctly.
READI aims to improve the specification, implementation, and verification of
requirements. A particular aim is to evolve the INCOSE guidelines for writing
requirements, so that recent innovations in intelligent data can be exploited.
READI uses ontologies, following W3C's OWL 2 standard in the intended way,
where constraints are subject to precise Description Logic reasoning. This will
support and partially automate work processes, improving development and use of
requirements across design and operations.
To provide a common, shared language of industrial assets and processes in the
form of OWL ontologies is crucial. This requires a broad-ranging collaborative
effort between subject matter experts and ontology modellers; while
challenging, the approach has already been proven successful in capital
projects. We obtain a clear separation between a generic vocabulary (classes
and relations), requirements expressed using the vocabulary (norms as rules),
and industrial assets described with the vocabulary (individual instances).
Agreement on common terminology is however not enough. We also need to ensure
that the vocabularies are applied in a uniform way. To this end, READI adopts
the Reasonable Ontology Templates (OTTR) language and framework. Ontology
patterns are developed to match the kinds of facts that need to be formalised,
then captured in OTTR templates. With a library of OTTR templates, we can
secure uniformity: as ontologies are built, as they are applied to integration
of existing data sources, and in analysis and reporting.
To make the ontology-based approach practical for the industry, a new kind of
repository service is needed, one that provides both ontologies and the
templates for using them in projects. In our presentation, we will demonstrate
how READI builds a platform for such a service, compliant with web best
practices including Linked Data, and exploiting the template library facilities
of the OTTR reference implementation Lutra.
