A method of operating a service registry and repository based on a triplestore comprises: receiving a request to aggregate a service document; shredding elements of the service document to create logical objects within the triplestore; for each logical object, searching for all policy attachments logical objects that have a relationship with the logical object; for each located policy attachment, retrieving details of the policy and building a list of policies and associated logical objects in the repository; and returning an indication of the list of polices and associated logical objects. The list of logical objects and associated polices is used to compile a service document containing details of policies that have relationships with the selected service document logical objects. Objects that have associated polices are rendered with a hypertext policy icon next to the object and selection of the hypertext policy icon opens a new window with the policy details.
