1. CRISP WP 17 1 / 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: 1)Evaluate and adapt metadata catalogues according to the RIs requirements. 2)Deploy and integrate metadata catalogue 3)Prototype of data mining on metadata services. 2Bessone 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. 3Bessone Nicola - ESRF

4. Evaluate metadata catalogues: Requirements 1)AAA 1.Authentication Modular integration of different authentication systems. 2.Authorization Customizable access control system. 3.Accounting Granular logging information levels. 4Bessone Nicola - ESRF

5. Evaluate metadata catalogues: Requirements 2)Metadata Model Core Scientific Metadata Model (CSMD) already been developed at STFC Bessone Nicola - ESRF5 Study Investigation Sample Dataset Datafile Parameter

6. Evaluate metadata catalogues: Requirements 3)Searching method Fulfill 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. 4)Cross platform 5)Service API Stable set of API possibly programming language agnostic. Bessone Nicola - ESRF6

7. Evaluate metadata catalogues: Requirements 6)Sustainability 1.Open source 2.Project organization: Actively maintained, Release plan (documentation, update mechanism, backward comp.), Patch release process (security, bug fix) 3.Cutting edge Technology 7)License Free of charge Bessone Nicola - ESRF7

8. Evaluate metadata catalogues: Requirements 8)Data policy Dynamic authorization system. 9)Scalability & Performance ILL host ~2’000 experiment /year producing ~10’000 datasets. Other facilities possibly more… 10)Data ingestion Manually & automatic + possible harvest (OAI-PMH) 11)Security Protect intellectual property. Bessone Nicola - ESRF8

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. 10Bessone Nicola - ESRF

11. Evaluate metadata catalogues: ICAT Authentication plug-in Rule based 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) 11Bessone Nicola - ESRF

12. Evaluate metadata catalogues: ICAT Plug-in for DAWN/Mantid Licence: FreeBSD Web interface: TopCAT In use at 11+ RIs 12Bessone 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 - ESRF13

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 16Bessone 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 - ESRF17
