HL7 Services Aware Interoperability Framework

HL7 Services Aware Interoperability Framework is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand HL7 Services Aware Interoperability Framework rather than just read about it. In short: This article documents the effort of the Health Level Seven(HL7) community and specifically the former HL7 Architecture Board (ArB) to develop an interoperability framework that would support services, messages, and Clinical Document Architecture(CDA) ISO 10871. HL7 provides a framework and standards for the exchange, integration, sharing, and retrieval of electronic health information.

Key takeaways

HL7 Services Aware Interoperability Framework belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HL7 Services Aware Interoperability Framework to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HL7 Services Aware Interoperability Framework from memory before moving on to harder problems.

Reference excerpt

This article documents the effort of the Health Level Seven(HL7) community and specifically the former HL7 Architecture Board (ArB) to develop an interoperability framework that would support services, messages, and Clinical Document Architecture(CDA) ISO 10871. HL7 provides a framework and standards for the exchange, integration, sharing, and retrieval of electronic health information.

SAIF Overview The HL7 Services-Aware Interoperability Framework Canonical Definition (SAIF-CD) provides consistency between all artifacts, and enables a standardized approach to enterprise architecture (EA) development and implementation, and a way to measure the consistency. SAIF is a way of thinking about producing specifications that explicitly describe the governance, conformance, compliance, and behavioral semantics that are needed to achieve computable semantic working interoperability. The intended information transmission technology might use a messaging, document exchange, or services approach. SAIF is the framework that is required to rationalize interoperability of standards. SAIF is an architecture for achieving interoperability, but it is not a whole-solution design for enterprise architecture management. The informative document may be found at Public SAIF CD. Since the release of this document, the SAIF-CD has been balloted as a Draft Standard for Trial Use. The document will be made available by the end of May, 2012. A Short introduction to SAIF was made to provide insight to users of the SAIF-CD.

Document Divisions The SAIF-CD consists of the following sections:

Introduction Governance Framework (GF) Behavioral Framework (BF) Information Framework(IF) Enterprise Consistency and Conformity Framework (ECCF) Interoperability Specification Matrix (ISM) Compliant SAIF Implementation Guides Appendix

Introduction The SAIF Introduction and Overview describes the general constructs that frame the SAIF. SAIF represents a synthesis of best practices and concepts from multiple architectural frameworks. This introduction to SAIF goes into a lot of technical depth and assumes you are already familiar with architectural standards and the HL7 organization.

Governance Framework The Governance Framework (GF) describes the motivation for, the structure, content and utilization of the GF. The ECCF and BF are discussed in detail in separate documents, and are mentioned in the course of this document only when necessary to either contextualize or logically link GF content to the larger context of the Services Aware Interoperability Framework.

Behavioral Framework The Behavioral Framework (BF) provides a set of constructs for defining the behavioral semantics of specifications, which enable working interoperability. As a result, the focus of the BF is accountability – a description of “who does what when.” Accountability describes the perspective of the various technology components that are involved in a particular instance or scenario designed to achieve Working Interoperability. The BF is technology-neutral and, therefore, can be used within model-driven specification stacks.

Information Framework The Information Framework (IF) is a SAIF-compliant recasting of existing HL7 expertise regarding the specification of static semantics. The Information Framework will draw on the information available from the following sources:

Storyboards Domain Analysis Models (DAM) Reference Information Model (RIM) ISO21731 Vocabulary concepts HL7 Core Principles

Enterprise Consistency and Conformity Framework The major goal of the Enterprise Consistency and Conformity Framework (ECCF) is enabling working interoperability between different users, organizations, and systems. The ECCF is manifest in a structure called the ECCF specification stack (SS). This structure identifies, defines, organizes, and relates a set of artifacts that collectively specify the relevant semantics of a software component specification or other system-of- interest. In summary, the ECCF SS provides an organizational framework in which inter-related artifacts are sorted by content – for example a Unified Modeling Language (UML) activity diagram in the Business viewpoint that contains static data constructs (for example, documents or data structures) which passes between the various structures would all have the relevant static constructs detailed in artifacts, specifically, business rules, information constructors, behavioral contracts, and level-of-abstraction.

Interoperability Specification Matrix (ISM) The Interoperability Specification Matrix (ISM) defines a 5-column-by-3-row matrix (“table”) which distributes the multiple aspects of a given component's specification across the various cells of the matrix. The structure of the ISM is based on proven cognitive models for describing complex systems which revolve around the notion of partitioning complexity based on a number of Dimensions while simultaneously viewing each of these dimensions from multiple Perspectives.

Compliant SAIF Implementation Guides This section defines the creation of a compliant implementation guide.

Worked examples

Example 1 — a first encounter with HL7 Services Aware Interoperability Framework

Start with the simplest possible case. Write down what HL7 Services Aware Interoperability Framework claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to HL7 Services Aware Interoperability Framework before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about HL7 Services Aware Interoperability Framework ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of HL7 Services Aware Interoperability Framework

In research: HL7 Services Aware Interoperability Framework appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses HL7 Services Aware Interoperability Framework in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: HL7 Services Aware Interoperability Framework is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agent-based software, American National Standards Institute, Data interchange standards, so understanding it makes those chapters shorter.
In everyday life: Look for HL7 Services Aware Interoperability Framework outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
