|---|
| 1 | LOINC timeline changes - please refer to Roadmap link here LOINC | July 2018 and potentially other future releases. |
| 2 | 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 |
| 3 | Groupers Chemical structure - Most existing concepts remodeled, with modeling and terming updated per editorial guidelines
- Top level groupers 763760008 | Medicinal product categorized by structure (product) and 767102007 | Medicinal product categorized by chemical element (product) created; this is an incremental improvement and there may still be missing subtypes
Groupers Dispositions - Most existing concepts remodeled, with modeling and terming updated per editorial guidelines
- Top level grouper 766779001| Medicinal product categorized by disposition (product) created; this is an incremental improvement and there may still be missing subtypes
Groupers Intended site - All existing concepts remodeled, with modeling and terming updated per editorial guidelines
Medicinal product (MP) - Most existing concepts remodeled (>3400), with modeling and terming updated per editorial guidelines
- Semantic tag updated to (medicinal product)
- Terming update to include "product" in Preferred Terms in progress but not visible in alpha release
Medicinal product form (MPF) - Most existing concepts remodeled (>1300), with modeling and terming updated per editorial guidelines
- Semantic tag updated to (medicinal product form)
Clinical drug (CD) - Existing concepts are in the process of being remodeled and are not ready for review at this time
- Preview of these concepts will be made available at a later date
Pharmaceuticaldose form - Most existing concepts remodeled, with modeling and terming updated per editorial guidelines
- Semantic tag updated to (dose form)
General The Alpha Release is a snapshot of the work-in-progress authoring environment; not all concepts are in scope for review at this time. Feedback given for concepts noted as out of scope will be rejected. For drugs: - Review should be limited to sufficiently defined inferred descendants of 763158003 | Medicinal product (product)
- Primitive concepts are out of scope for review
- Concepts with semantic tag (clinical drug) are out of scope for review
- Concepts with semantic tag (product) and containing product strength are out of scope for review
For dose forms: - Review should be limited sufficiently defined inferred descendants of 736542009 | Pharmaceutical dose form (dose form)
- Primitive concepts are out of scope for review
- Concepts without semantic tag (dose form) are out of scope for review
- Documentation:
- Editorial Guide draft version for the Medicinal Product Hierarchy available for review
- Editorial Guide draft version for the Pharmaceutical Dose Form Hierarchy available for review

| 4 | Summary of Substances Changes New hierarchies: Disposition (disposition) New semantic tags (disposition) New attribute types Has disposition Is modification of Attribute type changes Populated |Has disposition| grouper (n ≈ 150) Groupers Updated modeling, definition status, and terming for groupers representing disposition (n ≈ 150) with associated change in stated parents for existing descendants (n ≈ 9000) Briefing papers: Documentation created or updated including: - Editorial Guidelines for Modeling and Terming for Substance hierarchy
- Editorial Guidelines for Modeling and Terming for Disposition concepts
General content maintenance including: - Addition of X concepts as a result of gap analysis to identify missing concepts representing hydrates.
- Addition of X concepts to represent substances as a result of content requests, new drug approvals, or gaps identified internally.

| 5 | 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.

| 6 | 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
