Query: Non-Concept Software Subsystems: Tangible and Intangible   Concepts modified by a Non- prefix apparently denote a negation, an opposite
of the concept without this prefix. But, generally the situation is rather
subtle: non- implies only partial negation and the concept suggests preserved
identity with some reduced quality or absent attribute. In this work tangible
and intangible software subsystems based upon Non- concepts are defined and
pluggable ontologies are proposed for their representation. Pluggable
ontologies are a kind of nano-ontologies, which by their minimal size
facilitate fast composition of new software subsystems. These ontologies are
made pluggable by Design Sockets, a novel kind of class. These are abstract
connectors for removed/added parts, functionalities or identities, and for
subdued qualities. Design Sockets are the basis of a Design Pattern for
dynamically modifiable software systems. Pragmatic implications of Non-
concepts include manageable design of product lines with multiple models. Non-
concepts are also relevant to the controversy whether composition is or is not
identity. The resolution is not sharp. Identity is entangled with composition,
and is preserved to a certain extent, until further removal causes identity
breakdown.
