Reference Model for Service Oriented Architecture 1.0 Committee Specification 1, 2 August 2006 Document Model for Service Oriented Architecture is an abstract framework for understanding significant entities and relationships between them within a service-oriented environment, and for the development of consistent standards or specifications supporting that environment.It is based on unifying concepts of SOA and may be used by architects developing specific service oriented architectures or in training and explaining SOA.
A reference model is not directly tied to any standards, technologies or other concrete implementation details.
It does seek to provide a common semantics that can be used unambiguously across and between different implementations.The relationship between the Reference Model and particular architectures, technologies and other aspects of SOA is illustrated in Figure 1.While service-orientation may be a popular concept found in a broad variety of applications, this reference model focuses on the field of software architecture.The concepts and relationships described may apply to other "service" environments; however, this specification makes no attempt to completely account for use outside of the software The errata page for this specification is at: rm-cs 2 August 2006 Copyright

21 The role of a reference architecture for housing would be to identify abstract solutions to the 22 problems of providing housing.
A general pattern for housing, one that addresses the needs of its 23 occupants in the sense of, say, noting that there are bedrooms, kitchens, hallways, and so on is a 24 good basis for an abstract reference architecture.The concept of eating area is a reference 25 model concept, a kitchen is a realization of eating area in the context of the reference 26 architecture.27 There may be more than one reference architecture that addresses how to design housing; for 28 example, there may be a reference architecture to address the requirements for developing 29 housing solutions in large apartment complexes, another to address suburban single family 30 houses, and another for space stations.
In the context of high density housing, there may not be 31 a separate kitchen but rather a shared cooking space or even a communal kitchen used by many 32 families.33 An actual
architecture would introduce additional elements.
It would incorporate 34 particular architectural styles, particular arrangements of windows, construction materials to be 35 used and so on.A blueprint of a particular house represents a specific architecture as it applies to 36 a proposed or actually constructed dwelling.

The concepts and relationships defined by the reference model are intended to be the 48 basis for describing references architectures and patterns that will define more specific categories 49 of SOA designs.
