Dear WG Use Case - Aerospace Engineering Data Modelling =============================================== We are building an ontology capable of describing the objects involved in an aerospace engineering development project, and associating them with the reference documentation which defines the objects. The objects may be related to each other in several ways: parent-child relationships - a wing assembly has as child elements a wing, a wing spar, an engine ... constraints - the length property of the wing spar is constrained by the length property of the wing illustrations - an object in the ontology may be portrayed by a diagram in a source document All aircraft are individually different, so we need to be able to make statements about instances of classes as well as about the classes themselves. We also have consistency rules which enable us to say things like "the existence of a member of class A entails the existence of a member of class B" We are experimenting with semantic web technologies (RDF, DAML and extensions) to model the data in order to support visualisation and navigation based on object relationships (rather than physical or documentation structure) and support reliable transformations between different representations of the data. We are particularly interested in the languages themselves (for modelling and expressing logical relationships) and in graphical and other techniques for visualising and navigating the ontologies.
