Welcome and apologies | | - Question - Are there any conflicts in the current meeting schedule for October business meeting?
| | Actions from last week | | - Actions from last week:
- Additional use cases for term searching in ECL?
- Search types? Include regex? Does anyone have a regex ABNF?
- Language features required in ECL?
| | Introducing term searching to ECL | Linda Bird | Syntax {{ term = [ lexicalSearchTypetermSearchType : ] ":"] String String" }} Term Lexical Search Type - Wild Card Match (collation) - e.g.
- {{ term = wild:"*heart*“ }}
- {{ term = wild (sv):"*hjärta*“ }}
- ??? Perl Regex - e.g.
- {{ term = regex:".*heart.*” }}
- Question: Does the query suddenly become order dependent? Yes
- *** Word Prefix Any Order - e.g.
- {{ term = match:“hear att” }}
- Default (word prefix any order) - e.g.
- {{ term = "hear att" }}
- {{ term = "*heart*“ }}
Potential Examples - << 64572001|Disease| {{ term= “*heart*”“heart”}}
- << 64572001|Disease| {{ term= “*heart*”“heart”, languageCode = "en"}}
- << 64572001|Disease| {{ term= “*heart*”“heart”, languageCode = "en"}} AND << 64572001|Disease| {{ term= “*heart*”“hjärta”, languageCode = "sv"}}
- << 64572001|Disease| {{ term= “heart”, languageCode = "en"}}{{ term= “hjärta", languageCode = "sv"}}
- << 64572001|Disease| {{ term= “heart”, languageCode = "en"}} OR << 64572001|Disease| {{ term= “hjärta", languageCode = "sv"}}
<< 64572001|Disease| ( {{ term= “heart”, languageCode = "en"}} OR {{ term= “hjärta", languageCode = "sv"}} )
<< 64572001|Disease| ( {{ term= “heart” AND term= “hjärta"}}
- (<< 64572001|Disease|: |Associated morphology| = *) {{ term= “heart”, languageCode = "en", }}{{ term= “hjärta", languageCode = "sv"}}
- (<< 64572001|Disease| {{ term= “*cardio*” }}) MINUS (<< 64572001|Disease| {{ term != “*heart*” }})
- ?? << 64572001|Disease| {{ term= “*cardio*” }} MINUS << 64572001|Disease| {{ term != “*heart*” }}
Use Cases - Intentionally define a reference set for chronic disease. Starting point was ECL with modelling; This misses concepts modelled using the pattern you would expect. So important in building out that reference set.
- Authors quality assuring names of concepts
- Checking translations, retranslating. Queries for a concept that has one word in Swedish, another word in English
- AU use case would have at most 3 or 4 words in match
- Consistency of implementation in different terminology services
- Authoring use cases currently supported by description templates
- A set of the "*ectomy"s and "*itis"s
Questions - Do we include 'typeId' - e.g. << 64572001|Disease| {{ D.term= “*heart*”, typeId = 900000000000013009 |Synonym| }}
- Do we include 'type' - e.g. << 64572001|Disease| {{ D.term= “*heart*”, D.type= synonym }}
- Do we include 'languageCode' - e.g. << 64572001|Disease| {{ D.term= “*heart*”, D.type= synonym, D.languageCode = “en” }}
- Do we include 'caseSignificanceId' - e.g. << 64572001|Disease| {{ D.term= “*Heart*”, D.caseSignificanceId= 900000000000017005 |case sensitive|}}
- Do we include 'caseSignificance' - e.g. << 64572001|Disease| {{ D.term= “*Heart*”, D.caseSignificance = sensitive }}
- Do we include 'language' and 'version' - e.g. << 64572001|Disease| {{ term = “*heart*” }}VERSION = http://…, LANGUAGE = (999001881000000108|Gastro LRS|, |GB English|)
- Do we include syntactic sugar - e.g.
- << 64572001|Disease| {{ preferredTerm= “*heart*”, languageRefSet = en-gb}}
- << 64572001|Disease| {{ fullySpecifiedTerm = “*heart*”, languageRefSet=en-gb}}
- << 64572001|Disease| {{ acceptableTerm = “*heart*”, languageRefSet = en-gb}}
- << 64572001|Disease|{{ preferredTerm= “*heart*”}} FROM version = X, language = Y
- Do we use/require the "D" at the start of "term"?
- How does this relate to description templates? How does this relate to SNOSTORM implementation.
- Packaging - Do we (over time) extend ECL with all the new Query Language features, and define a set of example ECL profiles - e.g. "Basic ECL", "ECL with basic term searching", "ECL with filters".
| | Executing maps | | Proposed extension to ECL to support the execution of maps - Example use cases
- Mapping from international substance concepts to AMT substance concepts
- Anatomy structure and part association reference set - e.g. find the anatomical parts of a given structure
- Potential syntax to consider
- Functional
- mapTarget (|Anatomy structure and part association refset|, << |Upper abdomen structure|)
- mapSource (|Anatomy structure and part association refset|, << |Liver part|)
- Dot notation + Attribute refinement
- |Anatomy structure and part association refset| . |mapTarget|
- |Anatomy structure and part association refset| . |referencedComponent| (Same as ^ |Anatomy structure and part association refset|)
- ( |Anatomy structure and part association refset|: |referencedComponent| = << |Upper abdomen structure ) . |mapTarget|
- ( |Anatomy structure and part association refset|: |mapTarget| = << |Upper abdomen structure ) . |referencedComponent|
- Dot notation + Filters
- ( |Anatomy structure and part association refset| {{ |referencedComponent| = << |Upper abdomen structure| }} ). |mapTarget|
- ( |Anatomy structure and part association refset| {{ mapTarget = << |Upper abdomen structure| }} ) . |referencedComponent|
- ^ ( |Anatomy structure and part association refset| {{ mapTarget = << |Upper abdomen structure| }} )
- Specify value to be returned
- ?|mapTarget|? |Anatomy structure and part association refset|
- ?|mapTarget|? |Anatomy structure and part association refset| {{ |referencedComponent| = << |Upper abdomen structure| }}
- ?|mapTarget|? |Anatomy structure and part association refset| : |referencedComponent| = << |Upper abdomen structure|
| | Returning attributes | Michael Lawley | Proposal from Michael: - Currently ECL expressions can match (return) concepts that are either the source or the target of a relationship triple (target is accessed via the 'reverse' notation or 'dot notation', but not the relationship type (ie attribute name) itself.
For example, I can write: << 404684003|Clinical finding| : 363698007|Finding site| = <<66019005|Limb structure| << 404684003|Clinical finding| . 363698007|Finding site| But I can't get all the attribute names that are used by << 404684003|Clinical finding| - Perhaps something like:
- ? R.type ? (<< 404684003 |Clinical finding|)
- This could be extended to, for example, return different values - e.g.
- ?? |Simple map refset|.|maptarget| ?? (^|Simple map refset| AND < |Fracture|)
| | URI Standard | | - 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
