Abstract
A computer readable medium includes executable instructions to define an individual publication schema for each heterogeneous source of a set of heterogeneous sources. Each individual publication schema specifies mapping rules between data from a heterogeneous source and a non-permanent structured instance of data. A non-permanent structured instance of data as defined by an individual publication schema is generated. An integration schema defining a set of integration rules for combining data from each non-permanent structured instance of data as defined by individual publication schema is established. A target non-permanent structured instance of data to include data from the plurality of heterogeneous sources based on at least one integration schema is formed.
