Flexible taxonomy for Service Repository
Taxonomy is a method used to classify entities, items, and categories, among other things.
The ultimate goal of taxonomy is to establish a hierarchy or structure of categories (in our
case, all SOA artifacts). In this sense, an ontology is a wider concept because it is primarily
responsible for the identification, separation, and description of categories, and it is further
used in our classification to establish relations. Ontology is closer to the theory of classific-
ation, originally defined by Aristotle as the first philosophy . Recall that that's where we
started in the first chapter—the identification of frameworks, principles, and characteristics
essential for our service-oriented architecture. Finally, we put them together and declared
relations and dependencies.
Now, we extend this initial hierarchy with the essential SOA elements to maintain optimal
composability as an immediate target and promote effective SOA Governance. The out-
come will lay a strong foundation for the entire Enterprise SOA Governance from all stand-
points—software architecture, business, and operations.
