| 1 | Browse Content Changes for the July 2020 Release The daily build is available to review changes made to content for the July 2020 release https://dailybuild.ihtsdotools.org/ Forthcoming concept inactivations, new concepts and changes to existing concepts can be reviewed using the tab 'Daily build.' | July 2020 International Release |
| 2 | Revision of IS A relationships for anatomy concepts The new anatomy concept model implemented the enhanced Description Logic features, e.g. reflexive and transitive properties, additional axioms, for consistent logical modeling. The inferred IS A relationships from the OWL anatomy ontology have been reviewed and the changes have been implemented in the production. The potential impact to other hierarchies, such as disorders, procedures, observables, situations etc are also reviewed as part of the project. The revision of cardiovascular, digestive and genitourinary systems have been included in the July 2019 release. The respiratory, nervous, integumentary, endocrine, immune, sensory organs, lymphoreticular, hematological systems will be revised in the January 2020 International release. Information about revision of IS_A relationships can be viewed here: | July 2020 International Release |

| 6 | Planned changes to 'Co-occurrent and due to' pattern During the implementation of the new Description Logic features a conflict was uncovered between the modeling of 'Co-occurrent and due to' and General Concept Inclusions (GCIs). This has resulted in the need to reconsider the modeling of "Co-occurrent and due' and update the Editorial Guide for this area. The plan is to update the Editorial Guide and all concepts that are currently modeled as 'Co-occurrent and due to' starting from the July 2019 release. | July 2020 International Release and future releases |
| 7 | WAS_A Inactivation reason of LIMITED/WAS_A is not allowed for any new content inactivations after the July 2018 release. The WAS_A association refset has not been updated thereafter. At the Editorial Advisory Group meeting in April 2019, agreement was reached to discontinue the maintenance of WAS_A relationships when inactivating concepts that have a historical association to an inactive concept. When changes are made to a historical relationship for a concept that was previously inactivated using WAS_A, effort will be made to assign a new historical relationship that facilitates traceability of the concept (e.g. DUPLICATE or AMBIGUOUS) as opposed to NON-CONFORMANCE TO EDITORIAL POLICY. Existing WAS_A relationships will be inactivated in a future release once a plan for batch reassignment of historical relationships has been developed. Until then, SNOMED International will not continue to use or maintain WAS_A relationships. | July 2020 International Release and future releases |
| 8 | Changes for 'On examination' (O/E) and 'Complaining of' (C/O) concepts
Content being inactivated will use the reason - component moved elsewhere. Note: some concepts will not have a replacement concept as they are groupers. For example: | July 2020 International Release |
| 9 | Traumatic Dislocation Traumatic dislocation concepts are being remodeled according to the new representation using DUE TO "Traumatic event". This work has been partially completed for the Jan 2020 release, resulting in the remaining subhierarchies moving from under "Traumatic dislocation of joint" to "Dislocation of joint". These remaining subhierarchies will be remodeled for the July 2020 release. | July 2020 International Release |
| 10 | Planned changes to Implantation and Insertion procedures Work commenced on content tracker IHTSDO-175 IHTSDO-175 - Getting issue details... STATUS Ongoing structural changes for the Procedure concepts related to the content tracker: | July 2020 International Release |
| 11 | Replacement of the Stated Relationship files with the new OWL Axiom refset files A set of documentations has been developed to support the Logic Profile Enhancements.
