Ontoserver 6.7
This release of Ontoserver introduces the following new features:
ECL 2.0 feature: History supplements
The new history supplement syntax allows the a set of SNOMED CT concepts matched in an ECL (sub-)expression to be augmented by corresponding concepts from specifed History Association reference sets.
For example, the expression << 195967001 |Asthma| {{ +HISTORY (900000000000527005 |SAME AS association reference set|) }} will match Asthma and all its descendants as well as all (inactive) concepts that map to them in the 900000000000527005 |SAME AS association reference set| History Association reference set.
ECL 2.0 features: Extended memberOf and Member Filters (since 6.7.1)
ECL 2.0 introduces extended functionality for the memberOf operator as well as the ability to match against specified columns of a reference set.
In the former, the memberOf operator can optionally be followed by a specified field name in square brackets to instead return the contents of the specified field from the reference set(s).
For example:
^ [targetComponentId] 900000000000527005 |SAME AS association reference set|
Member filters can be applied only in the context of a memberOf sub-expression and allow matching against specified columns to return a subset of the reference set members.
For example:
^ 447562003 |ICD-10 complex map reference set| {{ M mapTarget = "J45.9" }}
These two features can be combined:
^ [targetComponentId] 900000000000527005 |SAME AS association reference set| {{ M referencedComponentId = 67415000 |Hay asthma| }}
ECL 1.5 and 1.6 features: Concept and Description Filters
