  Abstract =	 {Accessing knowledge of a single knowledge source
                  with different client applications often requires
                  the help of mediator systems as middleware
                  components. In the domain of theorem proving large
                  efforts have been made to formalize knowledge for
                  mathematics and verification issues, and to
                  structure it in databases. But these databases are
                  either specialized for a single client, or if the
                  knowledge is stored in a general database, the
                  services this database can provide are usually
                  limited and hard to adjust for a particular theorem
                  prover. Only recently there have been initiatives to
                  flexibly connect existing theorem proving systems
                  into networked environments that contain large
                  knowledge bases. An intermediate layer containing
                  both, search and proving functionality can be used
                  to mediate between the two. In this paper we
                  motivate the need and discuss the requirements for
                  mediators between mathematical knowledge bases and
                  theorem proving systems. We also present an attempt
                  at a concurrent mediator between a knowledge base
                  and a proof planning system.},
