This major version has support for Complete OWL SNOMED releases with no need for any active stated relationships. It also supports authoring using OWL axioms.

Thanks again to everyone who got involved in the questions, issues and fixes during this release!

Breaking

  • Elasticsearch reindex is required.
    • Indices have been renamed to a simpler, more readable format. For example es-rel has been renamed to relationship.
    • Default number of shards per index has been changed to 1 (configurable in application.properties).
  • Renamed concept additionalAxioms field to classAxioms.
  • Rename classification branch metadata keys inline with RVF.

Features

  • OWL Axiom Support:
    • Import complete OWL versions of SNOMED CT.
    • Stated hierarchy navigation using axioms.
    • Stated ECL using axioms.
    • Authoring using only axioms without any active stated relationships.
    • Concept definition status set automatically using axiom definition status.
  • Search:
    • Description search semantic tag counts and filtering.
    • New refset member search with aggregations (totals per reference set).
    • Search for refset members by a concept id within an OWL axiom expression.
    • Search for refset members containing OWL axiom class axioms or GCI axioms.
  • FHIR:
    • Support for multiple languages
      • Accept-Language request header respected.
      • Valueset expand operation 'displayLanguage' and 'designations' parameters supported.
    • Add support for expand operation 'filter' parameter.
    • Add support for offset, count and total in ValueSet expand operation.
    • Add support for CodeSystem lookup properties.
    • Add support for all implicitly defined FHIR valuesets.
    • Add support for maps (ICD-10, CTV-3) including historical associations.
  • Productionisation:
    • New multithreaded load test harness (ManualLoadTest.java) can be used to simulate many authoring users in order to evaluate different deployment configurations.
    • Concept searchAfter parameter allows scrolling through more than 10K results.
  • Extensions:
    • Basic extension upgrade support (via POST /codesystems/{shortName}/migrate).
  • Other:
    • Added reference set member create and update functionality to REST API.
    • Ability to load concepts from version control history within the same branch.

Improvements

  • Elasticsearch:
    • Recommended Elasticsearch version updated to 6.5.4.
    • Number of index shards and replicas is now configurable. Defaults to 1 shard and 0 replicas.
  • FHIR:
    • Upgrade FHIR API from DSTU3 to R4.
    • Allow valueset expansion against other imported editions.
    • Allow FHIR requests to access MAIN (or equivalent) as well as versioned branches.
    • Automatically populate server capabilities version from maven pom.
    • Update documentation: paging and filtering, valueset defined via refset.
  • Authoring:
    • Automatically remove inactivation members when concept made active.
    • Automatically remove lang refset members which description made inactive.
    • Ensure refset member effectiveTime is updated during changes.
    • Exclude synonyms when finding conflicts during branch merge.
    • OWL Axioms included in integrity check functionality.
    • Branch lock metadata added to describe currently running commit.
    • New SNOMED Drools Engine validation engine with axiom support.
    • Many Drools validation fixes.
    • Ability to reload validation assertions and resources.
    • Updated baked in MRCM XML.
  • Classification:
    • Classification save stale results check.
    • Allow saving classification results with greater than 10K changes.
    • Classification results can change existing relationships.
  • Branch merging:
    • Details of integrity issues found during a promotion included in API response.
    • Exclude non-stated relationships.
    • Concepts can be manually deleted during branch merge review.
  • RF2 Export:
    • New reference set types for RF2 export including: Description Type, Module Dependency and Simple Type. Note that Snowstorm does not yet calculate the Module Dependency members.
    • Carriage return line endings in RF2 export in line with RF2 specification.
    • Combine OWL Axiom and OWL Ontology refsets in RF2 export.
    • Add transientEffectiveTime option in RF2 export.
  • Improved Docker instructions.
  • ECL slow query logging.
  • Branch metadata can contain objects.
  • Binary for Elasticsearch unit tests cached in user home directory.
  • Base, head and creation date stamps and epoch milliseconds on branch response.
  • Authoring traceability logging of inferred changes capped to 100 (configurable).
  • Moved semantic index rebuild endpoint to admin area in Swagger.
  • Refset member search allows ECL in referenceSet parameter.
  • Authoring traceability appended to separate log file.

Fixes

  • FHIR:
    • Fix finding latest code system version.
  • Remove extra tab in header of some refset export files.
  • Fix for attribute group disjunction in ECL.
  • Clean up concept Elasticsearch auto-mapping, remove unpopulated fields.
  • Automatically create snomed-drools-rules directory if missing.
  • Additional axioms and GCI axioms included in branch merge.
  • Identify branch merge conflict when concept deleted on either side of the merge.
  • Prevent importing three bad relationships from international snapshot as stated and inferred.
  • Version endpoint format corrected to JSON.
