BS EN ISO 12967-1:2011

1   Scope This part of ISO 12967 provides guidance for the description, planning and development of new systems, as well as for the integration of existing information systems, both within one enterprise and across different healthcare organizations , through an architecture integrating the common data and business logic into a specific architectural layer (i.e. the middleware ), distinct from individual applications and accessible throughout the whole information system through services , as shown in Figure 2.

This part of [ISO 12967](/search?q=ISO%C2%A012967) is also independent from, and does not imply either explicitly or implicitly, any
  specific technological solution or product for its deployment. Accordingly, the formalization
  of the architecture according to two lower levels of the ODP reference model, the
  engineering and technology viewpoints, is outside the scope of this part. 
The language and notations used here for specifying the architecture are based on
  UML (Unified Modelling Language) complemented by case studies and other paradigms
  widely utilized by other standards in health informatics. The level of the specification
  is complete and non-ambiguous enough to allow its implementation into the specific
  physical and technological scenarios adopted by the various healthcare  organizations  and vendors. For this exercise, it is recommended to fol...
