Description Logic
Description logics (DL) are a family of formal knowledge representation languages. Many DLs are more expressive than propositional logic but less expressive than first-order logic. Description logics are often named as one of the tools that can support the Semantic Web and thus help to make this vision reality.
There are general, spatial, temporal, spatiotemporal, and fuzzy description logics, and each description logic features a different balance between expressive power and reasoning complexity by supporting different sets of mathematical constructors.
In Borhan, we have the Description Logics Course that we describe what they are and what they can do for the Semantic Web. Description logics are very useful for defining, integrating, and maintaining ontologies, which provide the Semantic Web with a common understanding of the basic semantic concepts used to annotate Web pages.

Very cool. Looks like fun – necessary logics and reasoning skills to Ontologist and for those developing Ontology-First software development tool chains.
