When three of the biggest standards groups agree on something, it must be big. And the big topic is architecture, or the need for more of it SOA.
OASIS, OMG,
and The Open Group -- the SOA and Web services standards triumvirate -- have jointly published a new white paper called "Navigating the SOA Open Standards Landscape Around
Architecture." Message: It's not about the technology, it's all about the Architecture -- the "A" in SOA.
The joint white paper talks about SOA reference models, ontologies, reference architectures, maturity models, modeling languages, and governance. The paper observes that The Open Group and OASIS actually have very similar SOA reference models, although some terms may represent different architectural views.
The OASIS Reference Model for SOA is intended to capture the "essence" of SOA, as well as provide a vocabulary and common understanding of SOA. The goals of the reference model include a common conceptual framework that can be used consistently across and between different SOA implementations, common semantics that can be used unambiguously in modeling specific SOA solutions, unifying concepts to explain and underpin a generic design template supporting a specific SOA, and definitions that should apply to all SOA.
The Open Group SOA Ontology is similar to the above OASIS Reference Model for SOA in that it captures a set of related concepts within the SOA space and explains what they are and how they relate to each other. The objectives are to facilitate understanding of these terms and concepts within the context of SOA, and potentially to facilitate model-driven implementation. The ontology is represented in OWL (Web Ontology Language) to enable automation and allow tools to process it; for example, reasoning applications could use the SOA ontology to assist in service consumer and provider matching, service value chain analysis, and impact analysis.
The Open Group SOA Reference Architecture is
intended to support the understanding, design, and implementation of
common system, industry, enterprise, and solution architectures
leveraging the principles of an SOA. This reference architecture is
designed to support different kinds of scenarios including those
involving consumer organizations, vendors, other standard bodies, and
other Open Group projects.
The Open Group Service Integration Maturity Model (OSIMM) provides corporations and IT practitioners with a means to create a roadmap and assess an organization's maturity within a complete SOA migration path.
The OASIS Reference Architecture for SOA Foundation is a view-based abstract reference architecture foundation that models SOA from an ecosystem/paradigm perspective. It specifies three viewpoints; specifically, the Service Ecosystem viewpoint, the Realizing SOAs viewpoint, and the Owning SOAs viewpoint.
