Interoperability between legacy systems has crucial importance for integration of many distributed systems. Within health information systems, the need for interoperability between legacy systems is well-known, as these are heterogeneous systems which have a long lifespan. An interesting example of health information systems is the Electronic Health Record (EHR), a virtual record of every health-related event, including hospital admission, general practitioner visit, exams, and allergies…

An Experience of using SoaML for Modeling a Service-Oriented Architecture for Health Information Systems
The main contribution of this work is to manipulate a relatively new modeling language to real-time operational problems related to the integration of health systems.
A Framework for Semantic Interoperability in Healthcare: A Service Oriented Architecture based on Health Informatics Standards
This paper presents a solution to interoperability in healthcare based on a standards-based middleware software architecture used in enterprise solutions translated into the healthcare domain using a messaging and modeling standard which upholds the ideals of the Semantic Web.
Interoperability in Healthcare: Benefits, Challenges and Resolutions
The paper suggests that the adoption of a standardized healthcare terminology, education strategy, design of useable interfaces for ICT tools, privacy and security issues as well as the connection of legacy systems to the health network are ways of achieving complete interoperability of electronic based Health Information Systems in healthcare.
A Service Identification Framework for Legacy System Migration into SOA
A novel framework which identifies the key services effectively based on a Model-Driven Architecture approach supported by a SOA meta-model and effective guidelines are proposed for identifying the optimal service granularity over a wide range of possible service types.
Reference Model for Service Oriented Architecture 1.0
This Reference Model for Service Oriented Architecture is an abstract framework for understanding significant entities and relationships between them within a serviceoriented environment, and for the

  • 2011
The state of the art in the area of enterprise systems as they relate to industrial informatics is surveyed, highlighting formal methods and systems methods crucial for modeling complex enterprise systems, which poses unique challenges.
SOA Reference Architecture: Standards and Analysis
An overview of the standards on SOA RA developed by ISO/IEC JTC1/SC38, The Open Group, OASIS and China is given and a set of guidelines are developed for the application of SOA RAs in common situations.
Adoption, non-adoption, and abandonment of a personal electronic health record: case study of HealthSpace
Policy makers’ hopes that “deploying” HealthSpace would lead to empowered patients, personalised care, lower NHS costs, better data quality, and improved health literacy were not realised, and the findings raise questions about how eHealth programmes in England are developed and approved at policy level.
The Economics of Architecture-First
