An object may exhibit multiple behaviors. Every behavior is unambiguously tied inwith a particular situation. With a context representing a situation and with signature as an object'sbare identity, through a number of signature instances an information model represents an object inmultiple contexts. This concept of context is especially characteristic of the metapattern approach toinformation modeling. Context is a recursive function of both signature and relationship between twosignatures at adjacent levels in the model. It suggests a development of the classic semiotic triad ofC.S. Peirce, at first onto a system of hexadic and next onto a system of enneadic dynamics. The designof the ennead, like the original triad, equals semiotics with ontology and epistemology. The increase inmodeling variety the metapattern offers is sketched through a fictional assignment. To gain a familiarperspective, basic assumptions underlying entity-atribute-relationship modeling and tradititional objectorientation are revisited. Next, the metapattern's assumptions as they relate to multiple, recursivecontexts are presented.
