Welcome, introductions and apologies

 
Expression Constraint Language
  • Publication of ECL v1.2
  • Discuss new requirements submitted by Michael
<< 125605004 |Fracture of bone| :

116676008 |Associated morphology| = 72704001 |Fracture|,
[0..0] (<<410662002 |Concept model attribute| MINUS 363698007 |Finding site| MINUS 16676008 |Associated morphology|) = *
Given knowledge of the concept model, this could be expressed (verbosely) as
<< 125605004 |Fracture of bone| :

 Is this requirement common enough for us to support the simplified form?
  • Agreement was reached that this (i.e. allowing an expression constraint in the place of an attribute name) is a reasonable requirement that should be added to a future version of the ECL (v1.3)
  • The detailed solution for this proposal needs to be worked through.
  • Work is also needed to develop a set of invalid expression constraints for testing
  • ECL v1.3 will be delayed until this work is complete
SNOMED Template Syntax
  • WIP version available at http://snomed.org/-sts (i.e. STS stands for 'SNOMED Template Syntax')
  • Final specification will be published at http://snomed.org/sts
  • Review skeleton document at http://snomed.org/-sts
  • SLPG to bring back issues, questions and suggestions for next week's meeting
  • Linda will start drafting expression template examples
