Ars Semantica provides consulting and development services for e-health.

E-health Strategy

We advise governments and companies in the UK, Australia, Sweden, Denmark, US, Brazil and others, on e-health strategy. Topics have included the following:

  • e-health programme design
  • flexibly standardising clinical information models
  • integrating clinical information and terminology
  • safely using e-health standards

E-health Standards

A recognised expert on e-health standards, Thomas Beale has worked on development of e-health standards, specifications within CEN TC 215, HL7, OMG HDTF, and the openEHR Foundation.


Thomas Beale is the original technical architect of the openEHR specifications, having worked since 2000 alongside numerous clinical and other colleagues in their development. These specifications are now managed by the openEHR Specifications Editorial Committee (SEC), and used in dozens of countries. They include the Reference Model, the Archetype Formalism (ISO 13606-2), and the Basic Meta-Model (BMM) formalism used by openEHR and HL7 CIMI.

Health IT Specifications Development

Expertise can be provided on undertaking new specifications development, including on:

  • development of formal languages and models for e-health information modelling and querying
  • use of terminology
  • defining specifications as a platform ecosystem

Specifications Governance and Publishing

We provide expertise on how to manage and publish technical specifications, such as for standards, a solution or product. Our governance approach includes a formal issue handling process, the use of Jira issue trackers, a release lifecycle and a fully defined change process. Our publishing approach is based on the toolchain developed for openEHR Foundation, using Asciidoctor and MagicDraw UML.

A specification ecosystem enables the creation of specifications from numerous input sources, including text, images, UML models, syntax specifications (e.g. Antlr) and so on. An example is the openEHR Task Planning specification. An overall ecosystem may include dozens or hundreds of specification artefacts, which have to be managed in a system of components in order for long-term governance to be possible. We provide advice based on long-term experience for building such ecosystems.
