  1. CRISP WP 171 / 2 Proposed Metadata Catalogue Architecture Document

  2. Work package 17 - IT & DM:Metadata Management and Data Continuum • Objectives:choose, implement data management and metadata mining services and establish an environment permitting a data continuum from raw data to publications across the participating Research Institutes (RIs): ILL, ESRF, SLHC and EuroFEL. • Task plan: • Evaluate and adapt metadata catalogues according to theRIs requirements. • Deploy and integrate metadata catalogue • Prototype of data mining on metadata services. Bessone Nicola - ESRF

  3. Evaluate metadata catalogues:Use cases • Identified a list of requirement based on ILL, ESRF and DASY use cases. • Select a list of most suitable metadata catalogue system on the market. • Match the requirements with features proposed by the metadata catalogues. Bessone Nicola - ESRF

  4. Evaluate metadata catalogues:Requirements • AAA • AuthenticationModular integration of different authentication systems. • AuthorizationCustomizable access control system. • AccountingGranular logging information levels. Bessone Nicola - ESRF

  5. Evaluate metadata catalogues:Requirements • Metadata ModelCore Scientific Metadata Model (CSMD) already been developed at STFC Parameter Investigation Sample Datafile Study Dataset Bessone Nicola - ESRF

  6. Evaluate metadata catalogues:Requirements • Searching methodFulfill user’s search needs, being easy to use and to access (web).Provide data mining to Facilities and Scientific management about data use/access/search/modific. • Cross platform • Service APIStable set of API possibly programming language agnostic. Bessone Nicola - ESRF

  7. Evaluate metadata catalogues:Requirements • Sustainability • Open source • Project organization:Actively maintained, Release plan (documentation, update mechanism, backward comp.), Patch release process (security, bug fix) • Cutting edge Technology • LicenseFree of charge Bessone Nicola - ESRF

  8. Evaluate metadata catalogues:Requirements • Data policyDynamic authorization system. • Scalability & PerformanceILL host ~2’000 experiment /year producing ~10’000 datasets. Other facilities possibly more… • Data ingestionManually & automatic + possible harvest (OAI-PMH) • SecurityProtect intellectual property. Bessone Nicola - ESRF

  9. Evaluate metadata catalogues:Metadata catalogue systems • ICAT • Dspace • Fedora • Ckan • Invenio • Tardis • ISPyB • iRODS • SRB-MCAT • MS. Zentity Bessone Nicola - ESRF

  10. Evaluate metadata catalogues:Selection result • Different solutions have been explored, amongst them ICAT appears to be the only one that currently fits the Data Model requirements. This is the key element for a successful implementation in a reasonable time frame. Bessone Nicola - ESRF

  11. Evaluate metadata catalogues:ICAT • Authentication plug-in • Rulebased authorization mechanism • Flexible metadata model • Search method: full-text, numerical and string search and SQL like query syntax • Set of API (Java and Python) • Database configurable (Oracle, Posgres and MySQL) • Federated search via TopCAT • Core Scientific Meta-Data Model (CSMD) Bessone Nicola - ESRF

  12. Evaluate metadata catalogues:ICAT • Plug-in for DAWN/Mantid • Licence: FreeBSD • Web interface: TopCAT • In use at 11+ RIs Bessone Nicola - ESRF

  13. Evaluate metadata catalogues:ICAT • Work-in-progress: • Improve web interface (TopCat) • Possibility to harvest (OAI-PMH) • Installation process • Synonym mechanism • Integration with Umbrella authentication Bessone Nicola - ESRF

  16. Deploy and integrate ICAT:ILL • Data policy published in Dec 2011 • Implementation Oct 2012 • ICAT deployment Dec 2012 • Currently, ingestion of the Data since Nov 2012 Bessone Nicola - ESRF

  17. Future work • Complete the deployment (ingestion) at the participating facilities. • Data mining • Collect uses cases from the different facilities • Currently all use cases are technically simple (no request for correlation for instance) • Work on the search engine (lucene) • Reporting Bessone Nicola - ESRF
