Quality of Service Policies Functional Profile
Policy and Rules Management allow non-developer secondary users to create policies and rules and apply them to services. The scope of policies includes, but is not limited to, definition and configuration of quality of service policies. Some key functional requirements for managing policies include capabilities to author policies and store policies, and to approve and validate policies and execute policies at runtime.
Quality of Service Policies include the following capabilities
- definition and configuration of Quality of Service policy and related rule
- apply policies to services
- author policy
- store policies
- approve policies
- validate policies
- execute policies at runtime
- descriptions to enable the policy modules to be visible, where the description includes a unique identifier for the policy and the metamodel representation of the meaning of terms used to describe the policy, its functions, and its effects;
- one or more discovery mechanisms that enable searching for policies that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual policy descriptions through some repository mechanism;
- accessible storage of policies and policy descriptions, so service participants can access, examine, and use the policies as defined.
- expression of assertion and commitment policy constraints;
- expression of positive and negative policy constraints;
- expression of permission and obligation policy constraints;
- nesting of policy constraints allowing for abstractions and refinements of a policy constraint;
- definition of alternative policy constraints to allow for the selection of compatible policy constraints for a consumer and provider;
- composition of policies to combine one or more policies.
- decision procedures which must be able to measure and render decisions on constraints;
- enforcement of decisions;
- measurement and notification of obligation constraints;
- auditability of decisions, enforcement, and obligation measurements;
- administration of policy and contract language artifacts;
- storage of policies and contracts;
- distribution of policies/contracts;
- conflict resolution or elevation of conflicts in policy rules;
- delegation of policy authority to agents acting on behalf of a client;
- decision procedures capable of incorporating roles and/or attributes for rendered decisions.
This Functional Profile includes, but is not limited to, the following capability elaborations:
Derived From Requirements
- Semantic Infrastructure Requirements::caGRID 2.0 Platform and Terminology Integration::Policy and Rules Management Policy and Rules Management allow non-developer secondary users to create policies and rules and apply them to services. The scope of policies includes, but is not limited to, definition and configuration of business processing policy and related rules, compliance policies, quality of service policies, and security policies. Some key functional requirements for managing policies include capabilities to author policies and store policies, and to approve and validate policies and execute policies at runtime. The Semantic Infrastructure will provide a mechanism to specify policies, including business processing policies and related rules, compliance policies, and quality of service policies. Tools and services for creating security specific policies will be provided by the caGRID 2.0 platform and will be used by the semantic infrastructure. All other policies specified in the Semantic Infrastructure will be enforced by the platform at runtime. Link to use case satisfied from caGRID 2.0 Roadmap: Each institution has different data sharing needs, access control needs, and business rules for processing that are defined and customized. For example, policy at the pathologist's institution may state that the patient is scheduled for a visit when the review is complete.
