Welcome and apologies | |
| | Move from ABNF to ANTLR | Daniel Karlsson | There has been a proposal For discussion: Daniel has proposed to change the primary syntax representation for all languages from ABNF to ANTLR. | Transitivity, Reflexivity &
Role chaining Proposed Language Features | | Proposed extension to ECL to support transitive Other topics for discussion. For example: ECL suggestions
Transitive relationships and role chaining in ECL (to align with new enhanced DL axioms) - Example 1
:- Direct relationship
- < 404684003 |Clinical finding|: << 246075003 |Causative agent| = << 58800005 |Streptococcus (organism)|
- Transitive relationship
- < 404684003 |Clinical finding|: << 246075003 |Causative agent|* = << 58800005 |Streptococcus (organism)|
- Example 2
:- Direct relationship
- < 71388002 ||: 363701004 |Direct substance| = 372687004 |Amoxicillin|
- Role chained relationship (via 738774007 |is modification of|)
- < 71388002 ||: 363701004 |Direct substance|* = 372687004 |Amoxicillin|
| | Executing maps | | Proposed extension to ECL to support the execution of maps (focusing on the resolution of historical refsets) - The specific use-case here comes initially from Jeremy and relates to being able to work with inactive concepts via the historical association maps. For example, given an ECL expression , e, that identifies a set of concepts 'c' to be used for retrieving patient records, you probably also want to retrieve records for sameAs (ec) and replacedWith (ec)
- Example 1:
- ??? (< 72704001 |Fracture| AND ^ 900000000000527005 |SAME AS association reference set|) . 900000000000533001 |Association target component|
| | URI Specification | Linda Bird | - Finalize and publish language and language instance URIs
| | Template Syntax | Linda Bird | New requirements - 2 slots must have the same value or
- 2 slots must have different values, or one
- The value of 1 slot must subsume the othervalue of another
- Default value for slots
| | URI Standard | Linda Bird | - Finalize and publish language and language instance URIs
| Query Language
- Summary from previous meetings
| | Examples: version and language Notes
- Allow nested where, version, language
- Scope of variables is inner query
|
| Examples: where Notes - Allow nested variable definitions, but recommend that people don't due to readability
- Scope of variables is the inner query
- No recursion e.g X WHERE X = 1234 MINUS X
- ie can't use a variable in its own definition
- ie X is only known on the left of the corresponding WHERE, and not on the right of the WHERE

| Language preferences using multiple language reference sets LRSs that use the same Language tend to use 'Addition' - i.e. child LRS only includes additional acceptable terms, but can override the preferred term E.g. Regional LRS that adds local dialect to a National LRS E.g. Specialty-specific LRS E.g. Irish LRS that adds local preferences to the en-GB LRS
LRSs that define a translation to a different language tend to use 'Replacement' - i.e. child LRS replaces set of acceptable and preferred terms for any associated concept
