1. A method comprising the steps of: using a generic resource programming model of a resource defining access modalities required for accessing said resource and defining a minimum specification of functionalities and attributes associated with a resource; using an adaptation mechanism comprising a plurality of deltas of code functionality for adapting said generic resource programming model to a respective plurality of runtime-specific resource models comprising respective different resource functionalities and respective different access modalities specific for a respective plurality of said different runtime environments; accessing said resource in its specific runtime environment by using a request comprising the respective delta of code functionality specific for the runtime environment of said resource; and wherein a plurality of different runtime environments exist and are used by either one of said resources or by a systems management application accessing one of said resources, wherein said different runtime environments require the usage of a web service resource framework comprising a plurality of respective different, runtime-specific web service standards.
