A Java framework for loading SNOMED CT components and reference set members from RF2 into memory, a database (or anything) via factory methods.
- Highly extensible
- Loading Profiles - only get the components or refsets you are interested in.
- Multithreaded - concepts load first, then relationships and descriptions in parallel, then all reference set memebers in parallel.
This project is oriented around the ComponentFactory and HistoryAwareComponentFactory. These interfaces allow a factory implementation to recieve the properties of every component and member. The HistoryAwareComponentFactory is useful when loading full files containing more than one release.
The default factory implementation targets memory. It builds a map of concepts with their descriptions and relationships connected. This is an extremely fast way to get hold the transitive closure for every concept.
// Create release importer
ReleaseImporter releaseImporter = new ReleaseImporter();
// Load SNOMED CT components into memory
ComponentStore componentStore = new ComponentStore();
releaseImporter.loadSnapshotReleaseFiles("release/SnomedCT_RF2Release_INT_20160731", LoadingProfile.light, new ComponentFactoryImpl(componentStore));
Map<Long, ? extends Concept> conceptMap = componentStore.getConcepts();
// Get tranitive closure for concept 285355007 | Blood blister (disorder) |
Set<Long> transitiveClosure = conceptMap.get("285355007").getAncestorIds();Feel free to fork and improve this project.
If you create a factory implementation based on this project please name the repo snomed-boot-X and share it here. e.g. snomed-boot-mysql.
