Glossary

• HL7 Health Level 7. Intended for all forms of
  medical data. Includes a RIM (Reference
  Information Model) and an XML schema.
• UMLS Unified Medical Language System.
  Metathesaurus and semantic network for medical
  concepts.
• MML Medical Markup Language. Similar to HL7 but
  not much support outside Japan (?).

3
Glossary

• SNOMED Systematized NOmenclature of MEDicine.
  Another medical vocabulary. Especially important
  is SNOMED-CT (Clinical Terms) for exchanging
  clinical data which is part of UMLS.
• CDISC Clinical Data Interchange Standards
  Consortium. An XML standard designed for exchange
  of clinical trials data. Strong industry support
  for this.

4
Glossary

• MIB Medical Information Bus (IEEE 1073). A set
  of OSI-level standards for medical device
  communication. Like a uPNP system for medical
  devices.

Discussion Questions

• The Berler et al. paper describes several
  architectures for shared data management
  centralized, distributed and combined. Discuss
  the tradeoffs of these.
• The HL7 RIM paper describes an implementation of
  HL7 for data export from a relational database.
  Given the description of HL7, what is a good data
  engine for querying HL7-type data?
• What are the advantages of a device-level
  standard like MIB? Or what practical
  differences are there between MIB and non-MIB
  medical sensors?
