| 1 | Revision of IS A relationships for anatomy concepts The new anatomy concept model has implemented the new Description Logic features, e.g. reflective and transitive property, general concept axioms, for consistent logical modeling. However, the new model cannot be implemented in production because these DL features currently are not available in production. The implementation of them will depend on the enhanced logic profile for SNOMED CT which is under development by the Modeling AG. Yet, the inferred IS A relationship from the OWL anatomy ontology can be reviewed and implemented in the production. This will utilise the outcomes of the new anatomy model as well as evaluate the design of the new model. In particular, it is important to review the changes of IS-A relationships in anatomy for quality assurance and minimise impact to other hierarchies, such as disorders, procedures, observables, situations etc. The first subject area for revision is the sub-hierarchy of skin structure. The majority changes have been made in the January 2018 release. The rest will be completed in July 2018 release. For July 2018 release, the subject area for revision of IS A relationships will be determined and updated in the following confluence page. | July 2018 International Edition |
| 2 | Improvement to the Release package naming convention In order to ensure that the status of each package is correctly identified, we will be capitalising the third element of the naming convention. For example therefore, instead of the January 2018 International Edition release package being called: SnomedCT_InternationalRF2_Production_20180131T120000Z.zip It will instead be called: SnomedCT_InternationalRF2_PRODUCTION_20180131T120000Z.zip Alpha/Beta releases will be called: SnomedCT_InternationalRF2_ALPHA_20180131T120000Z.zip SnomedCT_InternationalRF2_BETA_20180131T120000Z.zip This should have no impact on most users, this is provided for visibility of anyone who's upload routine might be case-sensitive. | January 2018 International Edition |
| 3 | Improvement to the Release file naming convention for the Asssociation Reference file In order to improve the description of this file, we will be updating the file naming convention from: 'der2_cRefset_AssociationReferenceSnapshot_INT_*.txt' to: 'der2_cRefset_AssociationSnapshot_INT_*.txt' ....as of the January 2018 International Edition | January 2018 International Edition |
| 4 | Summary of Drug Changes The following describes some of the deliverables scheduled for the January 2018 that continue to contribute to the delivery of this Strategy: NOTE: Numbers are still evolving and will likely change before the final version of the release notes are generated. New hierarchies
New semantic tags
New attribute types
Attribute type changes (for existing attributes) None Grouper None Medicinal product (MP) Updated ≈ 1100 existing concepts in accordance with new modeling and/or terming guidelines
Medicinal product form (MPF) Negligible number of changes Clinical drug (CD) Updated ≈ 3000 existing concepts changing terming from "Product containing X" to "Product containing only X" Note that the terming for these concepts was updated in the 2017-July release to reflect "Product containing X"; upon advice from the Working Group, we elected to notify the Member Forum, Project Group, and Working Group of the retraction/substitution rather than inactivate/replace these concepts New or updated concepts to support future simple map refset development For SNOMED CT to EDQM simple map refset:
For SNOMED CT to UCUM simple map refset:
