Overview
  • Central problems addressed by COMPAS
  • COMPAS assumptions and approach
  • Contribution to NEXOF
compas overview
COMPAS: Overview
  • COMPAS addresses a major shortcoming in today’s approach to design SOAs: Throughout the architecture various compliance concerns must be considered
  • Examples:
    • Service composition policies, Service deployment policies,
    • Information sharing/exchange policies, Security policies, QoS policies,
    • Business policies, jurisdictional policies, preference rules, intellectual property and licenses
  • So far, the SOA approach does not provide any clear technological strategy or concept of how to realize, enforce, or validate them
problem in detail
Problem in Detail
  • A number of approaches, such as business rules or composition concepts for services, have been proposed
    • None of these approaches offers a unified approach with which all kinds of compliance rules can be tackled
  • Compliance rules are often scattered throughout the SOA
  • They must be considered in all components of the SOA
  • They must be considered at different development phases, including analysis, design, and runtime
current practice vs compas approach
Current Practice vs. COMPAS Approach
  • Current practice:
    • per case basis
    • no generic strategy
    • ad hoc, hand-crafted solutions
  • COMPAS:
    • unified framework
    • agile
    • extensible, tailor-able
    • domain-orientation
    • automation
    • etc.

COMPAS Approach: Auditor’s View
  • Goals:
  • Support the automated controls better
  • Provide more automated controls

compas assumptions
COMPAS Assumptions
  • Types of compliance concerns tackled:
    • We concentrate on the service & process world
    • We concentrate on automated controls
  • Compliance expert selects and interprets laws and regulations
  • We deal with two scenarios of introducing compliance (and variations of them):
    • Greenfield
    • Existing processes
  • We distinguish:
    • High-level processes (e.g., BPMN), non-technical and “blurry”
    • Low-level processes (e.g., BPEL), technical and detailed
contribution to nexof
Contribution to NEXOF
  • Conceptual model contribution:
    • Conceptual model and terminology shared with NEXOF-RA, contributing to the Conceptual Reference Model (including Glossary) where compliance concerns could be acquired, modeled, realized, enforced and validated.
  • Architecture & Pattern contribution:
    • COMPAS contributed its overall architecture to NEXOF-RA to identify functional elements and derive architectural choices if not patterns to be proposed;
    • Design of a channel-based coordination pattern for design-time service composition within NEXOF-RA.
  • Participation & contribution to NEXOF-RA events
    • Open Call for Contribution, Investigation teams
  • 2 publications:
    • Collaborative web service discovery with the Implicit Culture Framework, NESSI Open Framework - Reference Architecture (NEXOF-RA), 2008 ;
    • Design Time Service Composition with Reo Coordination Tools, NESSI Open Framework - Reference Architecture (NEXOF-RA), 2008.
