SNOMED CT Template Syntax

Reconfirm decisions made in London include:

  • Slot names will be used (@name), slot references are out of scope for v1 (no $reference)
  • Slot names must be unique within a template OR Allow slot names to be repeated within a template and interpret this as meaning that the value is the same
    • For next week: Discuss an example in which repeated slot names may be required (e.g. finding and observable)
  • Default cardinality of all slots is [1..*]
  • Exclusive slot ranges will be represented by adding a '>' before the minimum and/or a '<' before the maximum - e.g. [[+int (>#20..<#30)]]
  • No minimum or maximum will be represented by omitting the respective value in the range - e.g. [[+int (#20..)]]

Examples of non-unique slots:

404684003 |finding| : {
       363698007 |finding site|  = [[ + @site ]],
       363714003 |interprets|  = (  363787002 |observable| :  704319004 |inheres in|  = [[ + @site ]]) }


|specimen| : {
       |specimen source topography|  = [[ + @site ]],
       |specimen procedure|  = (  |procedure|  : { |procedure site - Indirect|  = [[ + @site ]] } ) }

Examples of unique slots:

404684003 |finding| : {
       363698007 |finding site|  = [[ + @siteA ]],
       363714003 |interprets|  = (  363787002 |observable| :  704319004 |inheres in|  = [[ + (<< @siteA) @siteB ]] ) }
|specimen| : {
       |specimen source topography|  = [[ + @siteA ]],
       |specimen procedure|  = (  |procedure|  : { |procedure site - Indirect|  = [[ + (<< @siteA) @siteB ]] } ) }
