| 2 | Revision of IS A relationships for anaotmy 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 is concepts under for revision is the sub-hierarchy of skin structure. Majority changes are completed The majority changes have been made in the January 2018 release. The rest will be completed in July 2018 releaseand following releases. The subject area for revision of IS A revision in July 2018 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 |
| 3 | Summary of Drugs changes New hierarchies 766940004 | Role (role) and subhierarchy 766941000 | Therapeutic role (role) created with additional subtypes to be added in future releases New semantic tags (role) Attribute types New attributes created:
Grouper concepts representing disposition, intended site, and/or structure Grouper concepts representing disposition, intended site, and/or structure sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈550). New high level grouper concepts created as an incremental improvement with additional subtypes to be added in future releases:
Product role concepts Concepts representing product role relocated as stated descendants of 763087004 | Medicinal product categorized by role (product) with definition status = primitive and attributes inactivated (n≈ 400) For further details see Briefing Note Use of Additional Axiom Functionality and Remodeling Product Roles Medicinal product (MP) concepts - MP-containing concepts sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈ 3750). Includes the following attributes:
Medicinal product form (MPF) concepts - MPF-containing concepts sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈2100). Includes the following attributes:
Clinical drug (CD) concepts - CD-containing precisely concepts sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈ 4850). Includes the following attributes:
Documentation Notification for Briefing Notes, Editorial Guidelines, and other documentation updates are posted on the project group website as they become available; see Drug Model Working Group - Directory for details Briefing Briefing note - Use of Additional Axiom Functionality and Remodeling Product Roles.pdf | July 2018 International Edition |
| 4 | Summary of Substances Changes Dietary subhierarchy. To remove context of use from the substance concepts and manage the situation where substances can be both a pharmaceutical ingredient and a foodstuff (n≈80) that had a tag of “- dietary” in the Fully Specified Name (FSN) and the Preferred Term (PT) were inactivated. Replacement concepts concept without "-dietary" in the FSN and PT were created. The top level concept "Dietary substance (substance)" has been inactivated and replaced with a new concept "Edible substance (substance)". Radioactive isotope substances. These concepts have been remodelled and the terming normalised to provide consistent representation without the use of carats. Cancer related substance. The subhierarchy has now been removed. Some concept have been inactivated. Some have been moved within the substances hierarchy. Disposition Groupers
Structural Groupers
Combined Groupers (Structure + Disposition)
Role Groupers
The "Is modification" of attribute has been implemented (n≈1200) resulting in flattening of the substances hierarchy. Overall 447 new concepts added to the substances hierarchy. Just over 460 substance concepts have been inactivated in the July 2018 SNOMED CT release. Documentation Notification for Briefing Notes, Editorial Guidelines, and other documentation updates are posted on the project group website as they become available; see Project Status Substance Hierarchy for details. | July 2018 International Edition |
| 5 | Internal QA - Situation and Findings Test and procedure status: Inactivated 143 concepts in the Situations and Findings hierarchies with pattern "Test/procedure OFFERED" and "Test/procedure NOT OFFERED" as these represent an administrative status. | July 2018 International Edition |
| 6 | Internal QA - Qualifier Value Inactivation of Agencies and organizations (qualifier value) and subtypes: moved to UK extension i.e. 66 concepts inactivated. | July 2018 International Edition |
| 7 | Replacement of OWL conversion script with a link to the open source directory In January 2017 the original OWL conversion script (a.k.a. the "Spackman OWL script") was removed from the International Edition package, and has since been published as a separate artefact alongside each Release. Because this script does not recognize the two new OWL refsets (see section 3.3.2 of these Release Notes), the Terminology Release Advisory Group has determined that the script should no longer be distributed. Going forward, Release Notes will now include a link to the new open source OWL conversion toolkit that can be found in the following repository (including documentation on its use): https://github.com/IHTSDO/snomed-owl-toolkit Please contact SNOMED International at support@snomed.org if you would like to provide any feedback on ways to extend and improve the new toolkit. | July 2018 International Edition |
| 8 | Deprecation of the Technical Guide Exemplars document from the International Edition release package The Terminology Release Advisory Group has confirmed that there should be no impact from removing this almost entirely static document from the International Edition release package, and hosting it instead in a Confluence Page. From the July 2018 International release then, we will deprecate this file (doc_Icd10MapTechnicalGuideExemplars_[date].xlsx) from the Release package, and instead provide a link in the Release Notes to the new Confluence Page. Please see section 2.4.1.3 of the Release Notes for the relevant link. | July 2018 International Edition |

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

For SNOMED CT to UCUM simple map refset:
