Abstract and usage:

Framework is an algebraic structure whose purpose is capturing the topological or topology-like structure of a system from its externally observed properties. Formally, framework is
a formal context whose incidence relation is the membership relation. The objects are called *places* and the attributes are collections of places connected by a possible presence of
some physical object, for example, a particle. The set of attributes is called a *framology*. The structure may be used, for example, for investigation of topological properties of certain
causal structures, motivated by quantum gravity, interactions of particles, Feynman diagrams, information systems and databases or solutions of certain differential equations and their
global properties. The elements of framology are the places of the * dual framework* (for the definition of the dual framology, see, e.g.,
[1]) and they also may be considered as the *abstract points* of the original framework. The notion of a
*generalized distance* between two abstract points of a framework is inspired by the notion of *partial metrics* due to S. Matthews.
Our experimental application * Generalized Distances * checks if the original framework is correctly given by the input and then it calculates the
tables of three modifications of the generalized distance between the abstract points of the given framework. The calculations are based on various set operations on the given framology.
