(Commit: 0b558108437c05fcc3bed261778c953fe156192f) 4) Synonym and cross-reference enhancements: Expanded synonyms and cross-references to improve searchability and interoperability. (Commit: 7ae4a9bda1a2fc3e2baa5b305e16ea7b13230918) 5) Overall impact: Broader coverage and improved classification for neurological/developmental disorders and epilepsy, enabling more precise curation, analytics, and clinical research workflows.

April 2025: Delivered a targeted MONDO ontology bug fix to restore correct representation of 'variable age epilepsy syndrome' and re-align cross-references, improving data integrity and interoperability for epilepsy syndrome mappings.

March 2025: Substantial ontology stabilization and expansion for the mondo project. Focused cleanup removed obsolete terms, tightened hierarchies, and implemented obsoletion protections to improve data quality and maintainability. Expanded coverage with new terms and synonyms, fortified structural integrity with disjoint unions and cross-references, and refined labeling and taxonomy for consistency. Completed maintenance and data ingestion tasks to ensure up-to-date data feed and clear documentation. These efforts enhance search accuracy, analytics reliability, and interoperability for downstream clinical and research applications.

February 2025 MONDO repository: focused on term additions, data consolidation, taxonomy refinements, and cleanup to improve data quality, searchability, and downstream clinical mappings. The month delivered multiple new terms, extensive merging of disease entries, and ongoing taxonomy updates that enhance data integrity, cross-references, and maintainability for downstream consumers.

January 2025 — monarch-initiative/mondo: Expanded epilepsy ontology and governance cleanup to enhance data granularity, searchability, and terminology accuracy. Delivered: (1) epilepsy ontology expansion/refactor (new terms, refined synonyms/relationships, and consolidation of overlapping entries); (2) ontology term obsoletion, governance updates (deprecations, renames, and governance tag improvements). Overall: improved data quality, interoperability, and governance compliance, enabling more reliable clinical and research data integration. Notable commits include substantial term updates and merges (e.g., myoclonic-astatic epilepsy, SYNGAP1-related DEE) and age-specific terms, plus removal of incorrect references. Obsolete-term cleanup includes deprecation of absence epilepsy, electroclinical syndrome, infantile/early childhood epileptic encephalopathy, and adolescent/adult-onset epilepsy syndrome.

Concise monthly summary for 2024-12 focusing on ontology curation work in the Mondo repository (monarch-initiative/mondo).

November 2024 (2024-11) performance snapshot for the monarch-initiative/mondo repository focused on epilepsy ontology improvements, with contributions spanning taxonomy refinements, cross-reference hygiene, and provenance/documentation enhancements. Key features delivered: - Epilepsy ontology taxonomy refinements and alignment with ILAE classifications: reclassification of autoimmune epilepsy under immune epilepsy, moving DOID xrefs, removing a superclass, adjusting relationships, removing obsoletion markers, and updating synonyms to improve searchability and retrieval. Commits include updates such as Epilepsy/Review first: add new epilepsy terms per Epilepsy workshop/ILAE (#8281); exclude superclass on 'myoclonic-astatic epilepsy' (#8285); excluded superclasses from antibody mediated epilepsy (#8296); move DOID xref from 'autosomal dominant epilepsy with auditory features' (#8321); exclude superclass from DEE18 (#8323); reclassify autoimmune epilepsy as a child of immune epilepsy (#8453); add obs tags (#8458). - Ontology documentation and provenance enhancements: improved documentation and provenance for epilepsy entries, including adding a source URL for idiopathic generalized epilepsy and a clarifying comment for antibody mediated epilepsy representation in ILAE classifications. Commits include add source to 'idiopathic generalized epilepsy' (#8297); add comment to antibody mediated epilepsy (#8299). Major bugs fixed: - Taxonomy and cross-reference cleanup to improve data integrity: excluded superclasses and moved cross-references to correct terms, removed outdated or conflicting relations, and tagged items for traceability (commits #8281, #8285, #8296, #8321, #8323, #8453, #8458). - Documentation and provenance fixes ensuring sources and notes reflect current ILAE alignments (commits #8297, #8299). Overall impact and accomplishments: - Increased accuracy and consistency of epilepsy-related terms in Mondo, enabling more reliable retrieval and interoperability with ILAE classifications across downstream applications and research workflows. - Reduced semantic drift by realigning classifications, updating synonyms, and clarifying antibody-mediated epilepsy representation, improving curation efficiency and data quality. Technologies/skills demonstrated: - Ontology curation and OWL/OBO taxonomy management, xref handling, and superclass relationship adjustments. - Provenance documentation practices, source attribution, and annotation of detailed comments to support future maintenance. - Cross-repo collaboration with epilepsy ontology stakeholders and alignment with external classifications (ILAE).
