Research about ontology access, processing, and usage paves the way for realizing
important tasks in future applications requiring well-understood formal representation
formalisms as well as efficient and industrial-strength implementations. In this
report, we summarize the state of the art for most important application tasks of
this kind that use ontologies as their backbone. In addition to a formalization of the
tasks for some of the most important application scenarios, we also report on recent
theoretical and practical advances for their realization that have been achieved as
part of our work in the TONES project.
