  abstract=      "We shall develop a simple and natural formalization of the
     idea
of
     \textlessi\textgreaterclient-server\textless/i\textgreater
     architectures, and, based on this, define
a notion of
     \textlessi\textgreaterorthogonality\textless/i\textgreater
     between clients and servers,
which embodies strong
     correctness properties, and exposes the rich
logical
     structure inherent in such systems. Then we generalize
from
     pure clients and servers to
     \textlessi\textgreatercomponents\textless/i\textgreater,
     which provide
some services to the environment, and require
     others from it.
We identify the key notion of
     \textlessi\textgreatercomposition\textless/i\textgreater of
     such components,
in which some of the services required by
     one component are supplied
by another. This allows complex
     systems to be built from ultimately
simple components. We
     show that this has the logical form of
     the
\textlessi\textgreaterCut rule\textless/i\textgreater, a
     fundamental principle of logic, and that it
can be enriched
     with a suitable notion of \textlessi\textgreaterbehavioural
     types\textless/i\textgreater
based on orthogonality, in such
     a way that correctness properties
are preserved by
     composition. We also develop the basic ideas of
how logical
     constructions can be used to develop
     \textlessi\textgreaterstructured
interfaces\textless/i\textgreater
     for systems, with operations corresponding to
logical rules.
     Finally, we show how the setting can be enhanced,
and made
     more robust and expressive, by using
     \textlessi\textgreaternames\textless/i\textgreater (as
     in
the \&amp;pi;-calculus) to allow clients to bind
     dynamically to generic
instances of services."
