Abstract: A method, system and/or non-transitory computer readable medium is used with a service repository that stores service definitions for services. A query facility inspects service definitions in the service repository. The query facility determines, from the inspection, first attributes associated with a first service and different second attributes associated with a second service, the first and second attributes being related to syntactic and semantic aspects of the first and second services. Responsive to a service oriented request which indicates the first service, the query facility determines a composability of the first and second services in accordance with a service oriented query (SOQ) framework, based on the first and second attributes and rules regarding composability of attributes, the rules being in accordance with the SOQ framework, the composability of the first and second services being determined with respect to both the syntactic and semantic aspects of the first and second services.

Abstract: A computer system includes a processor and an electronic storage. The processor provides a service composition tree of services which are offered, wherein the tree is hierarchical and specifies relationships of the services which are offered within the service composition tree to each other; translates service composition trees and the relationships of the services represented in the trees into a directed acyclic graph (DAG) that represents the service composition trees, the DAG being redundancy-free; and performs a transitive traversal within the DAG among the services represented in the DAG to locate information, within the DAG, regarding the services, in relation to each other. The electronic storage stores the DAG accessed by the processor. A method according to the above will perform a transitive traversal service discovery of a DAG that is redundancy-free, and optionally is minimal weighted. A non-transitory computer-readable medium can perform the method.
