Workpackage 2 Presentation at DM2E Project Meeting 3, London

  1. 1. co-funded by the European Union Work Package 2 All WP Meeting 11th June 2013, London Kai Eckert, Evelyn Dröge
  2. 2. Timetable 16.04.2013 DM2E Review: Work Package 2 2 Q1 •2.1, 2.3: Test of external components (MINT, Silk, jMet2Ont, D2R), Data Survey •2.2: Basic entity structure of the model Q2 •2.1, 2.4, 2.5: Prototype of Infrastructure, Workflows, UI •2.2: Mapping workshops, further work on the DM2E data model Q3 •2.1: 2.4, 2.5: Softwaredesign of Intermediate Architecture, Foundational work •2.2: Combination of the DM2E model with Linked Data principles, Integration with Architecture Q4 •2.1, 2.4, 2.5: Provenance Model for DM2E Infrastructure, Web service development •2.2: DM2E Data Model 1.0, first stable and operational version. Q5 •Implementation of the DM2E Data Model in Mint. •Development of the Intermediate Version of the Infrastructure: due on July 15th.
  3. 3. DM2E Data Model 1.0 published Online Documentation: onto.dm2e.eu/dm2e
  4. 4. Further Documentation Current Version: DM2E Model v1.0 • Documentation: http://dm2e.eu/document/  Model description  OWL File • New changes in the model are shown in a next model version 1.1 on Redmine: https://dm2e.hu- berlin.de/redmine/projects/wp2/wiki/DM2E
  5. 5. Modelling Issues • Namespaces: – dm2e: <http://onto.dm2e.eu/schemas/dm2e/1.0/> . – dm2edata: <http://data.dm2e.eu/data/> . • How to reuse external vocabularies? – Specification: DM2E scope notes and original description of terms from other vocabularies • Modelling analogue to EDM (OAI-ORE) – Extensive use of properties instead of classes, e.g., 52 new properties for edm:ProvidedCHO – If possible: direct reuse of external vocabularies • Additional external vocabularies – Korbo (WP3), Bibliographic Ontology, FaBiO, Publishing Roles Ontology, VIVO Ontology, VoID 16.04.2013 DM2E Review: Work Package 2 5

  7. 7. DM2E v1.0 in Mint Different DM2E model interpretations in Mint Evaluation of those in three evaluation rounds
  8. 8. Evaluation of the DM2E model interpretations • 1st Evaluation – UBER – DM2E v1.0 - EDM Schema Approach - Resources are not related - Ranges are not taken into account  Schema is not further used – DM2E v1.0 Fixed Ranges + DM2E Schema Approach + Resources are related + Ranges are considered  Basis for the 2nd evaluation
  9. 9. Evaluation of the DM2E model interpretations • 2nd Evaluation – UBER/ONB – DM2E v1.0 Fixed Ranges • Schema has to be updated – DM2E v1.0 Fixed Ranges Short A • Loss of class specific properties • Excluded for further development – DM2E v1.0 Fixed Ranges Short B • Schema has to be updated – DM2E v1.0 Fixed Ranges Short C • Allows inconsistent mappings • Excluded for further development
  10. 10. Evaluation of the DM2E model interpretations • 3nd Evaluation – UBER/ONB/NTUA – DM2E v1.0 Fixed Ranges – DM2E v1.0 Fixed Ranges Short B We have to choose one of them now!
  11. 11. Next Steps of UBER in WP2 • Provide mapping help • Analyse your mappings – Which resources are not used? – Are any resources missing? • Revise the model – Smaller logical or typographical errors in the model can immediately be corrected – Other adaptions will be made over a longer development cycle (meaning a period of several months) Former mappings will remain valid! We need your feedback!

  14. 14. OmNom Ingestion Platform DM2E Review: Work Package 2 1416.04.2013
  15. 15. WP2 Infrastructure DM2E Review: Work Package 2 1516.04.2013
  16. 16. The Result: Linked Data DM2E All WP Meeting: Work Package 2 1611.06.2013
  17. 17. Workflow: Orchestration of Services DM2E All WP Meeting: Work Package 2 1711.06.2013
  18. 18. Workflows • OmNom: Distributed infrastructure to ingest and create data in DM2E. • Workflow = Dataflow • Data is created and transformed by web services • Components: – Input services (File services, D2R instances, OAI-PMH, ...) – Transformation services (Generic XSLT, MINT, R2R) – Ingestion services (Output of an ingestion pipeline) – Contextualization services (Silk) – Configuration Services (MINT and Silk act as editors) DM2E Review: Work Package 2 1816.04.2013
  19. 19. The Linked Data Gap • Linked Data publication is often one-way. • Linked Data as an export from the „real“ data. • This leads to a gap: YOUR data becomes separated from the Linked Data. DM2E Review: Work Package 2 1916.04.2013
  20. 20. Bridge the gap from YOUR data to Linked Data DM2E Review: Work Package 2 2016.04.2013 Image by courtesy of Kiril Havezov, sxc.hu (walker_M)
  21. 21. The DM2E Data Bridge DM2E Review: Work Package 2 2116.04.2013 This is YOUR data. This is the void:Dataset in DM2E.
  22. 22. Some more links are actually available... DM2E All WP Meeting: Work Package 2 2211.06.2013
  23. 23. Personalization and Security
  24. 24. Authentication Service ● Centralized Authentication and Authorization Service ● Centralized Storage of User Accounts ● User Account Schema based on MINT Model. ● Single Sign-On ● Standard Based: JAAS, Web Services/SOAP ● "Remember Me" support ● Password reset support
  25. 25. Contextualization • Silk: Silk Link Discovery Framework (UMA) • Definition of linkage rules to create links between Linked Data resources. DM2E Review: Work Package 2 2516.04.2013
  26. 26. Next steps • Intermediate Version (July 2013) – Complete transformation and ingestion infrastructure – Integrated contextualization – Connection with scholarly environment (WP3) DM2E Review: Work Package 2 2616.04.2013
