We examine a knowledge representation architecture to support context interchange
mediation. For autonomous receivers and sources sharing a common subject domain,
the mediator's reasoning engine can devise query plans integrating multiple sources and
resolving semantic heterogeneity. Receiver applications obtain the data they need in the
form they need it without imposing changes on sources. The KR architecture includes:
1) data models for each source and receiver, 2) subject domain ontologies, containing
abstract subject matter conceptualizations that would be known to experienced
practitioners in the industry, and 3) context models for each source and receiver that
explain how each source or receiver data model implements the abstract concepts
from a subject domain ontology. Examples drawn from the fixed income securities
industry illustrate problems and solutions enabled by the proposed architecture.
