  • 1. Metadata Sharing Module for OpenMRS Google Summer of Code 2010 Metadata Sharing Module - Rafał Korytkowski - 2010
  • 2. Team • Mentors: Darius Jazayeri & Jeremy Keiper • Student: Rafał Korytkowski Metadata Sharing Module - Rafał Korytkowski - 2010
  • 3. What is it all about? „In OpenMRS, we distinguish between data and metadata within our data model. Metadata represent system and descriptive data such as data types - a relationship type or encounter type. Metadata are generally referenced by clinical data but don't represent patient-specific data themselves. This provides a default abstract implementation of the OpenmrsMetadata interface.” [src: org.openmrs.OpenmrsMetadata, javadoc] • Metadata examples: locations, roles, order types, forms, reports, etc. • Most of them implement OpenmrsMetadata interface (except concepts) • Sharing use case: User A has defined 100 locations in Kenya and User B needs them as well, but does not have resources to define them himself. A way to export & import locations is needed. Metadata Sharing Module - Rafał Korytkowski - 2010
  • 4. Our goals • First release goals (GSoC „must have”): • Export a package of metadata as a file • Import a packaged file • Second release goals: • Publish a packaged file • Subscribe to a published package • Check for updates on subscribed packages (Possible integration with Remote Data Transfer Module by Kenny MacDonald) Metadata Sharing Module - Rafał Korytkowski - 2010
  • 5. Progress 1/2 • First release goals (GSoC „must have”): • Export a package of metadata as a file • Scan the classpath for metadata [done] • Serialize metadata to XML [done] • Indetify dependencies • Referenced objects [done] • Custom dependencies (e.g. defined in an XML field in html forms) [not done] • Package metadata in a zip file [done] • Store packages in the DB and allow for downloads [done] Metadata Sharing Module - Rafał Korytkowski - 2010
  • 6. Progress 2/2 • Import a packaged file • Upload packaged matadata [done] • Process metadata before import [not done] • Choose items to import [not done] • Merge imported metadata with existing items [not done] • Identify conflicts [not done] • Deserialize metadata [done] • Persist metadata in the database using proper OpenMRS services [done] Metadata Sharing Module - Rafał Korytkowski - 2010
  • 7. Demo Metadata Sharing Module - Rafał Korytkowski - 2010
  • 8. Q&A • Wiki: http://openmrs.org/wiki/Metadata_Sharing_Project • Blog: http://devyard.blogspot.com/ Metadata Sharing Module - Rafał Korytkowski - 2010
