Illustrative embodiments provide a computer-implemented method for configurable Unified Modeling Language building blocks. The computer-implemented method obtains a Unified Modeling Language specification and generates a set of logical units from the Unified Modeling Language specification to form a set of building blocks. The computer-implemented method further fetches desired blocks from the set of building blocks according to predefined criteria to form a set of desired blocks, and presents the set of desired building blocks to a requestor for execution of functions provided by the set of desired building blocks to complete a defined task.
