2. EPrints Workshop, January 20052 Overview Scholarly communications in Chemistry  Data, information, workflows and provenance The data publication bottleneck  e-Science and chemistry eBank UK  Information architecture, data flow and interoperability Challenges for the future  Expansion into other disciplines and data formats

3. EPrints Workshop, January 20053 Research & e-Science workflows Aggregator services: national, commercial Repositories : institutional, e-prints, subject, data, learning objects Data curation: databases & databanks Validation Harvesting metadata Data creation / capture / gathering: laboratory experiments, Grids, fieldwork, surveys, media Deposit / self- archiving Peer-reviewed publications: journals, conference proceedings Publication Validation Data analysis, transformation, mining, modelling Searching, harvesting, embedding Presentation services: subject, media-specific, data, commercial portals Resource discovery, linking, embedding Linking The scholarly knowledge cycle. Liz Lyon, eBankUK article. Ariadne, July 2003.

7. EPrints Workshop, January 20057 Data Overload! How do we disseminate? EPSRC National Crystallography Service The data deluge

8. EPrints Workshop, January 20058 CombeChem: eScience testbed Properties X-Ray e-Lab Analysis Properties e-Lab Simulation Video Diffractometer Grid Middleware Structures Database

9. EPrints Workshop, January 20059 Establishing common ground… Understand the data creation process Terminology and definitions –Data –Metadata –Datafile –Dataset –Data holding Different views –Digital library researchers, computer scientists, chemists –Generic vs specific –Modeller vs practitioner Aim for a common ontology Modelling the domain Creating a metadata schema

10. EPrints Workshop, January 200510 Crystallography workflow Initialisation: mount new sample on diffractometer & set up data collection Collection: collect data Processing: process and correct images Solution: solve structures Refinement: refine structure CIF: produce CIF (Crystallographic Information File format) Report: generate Crystal Structure Report RAW DATADERIVED DATARESULTS DATA

12. EPrints Workshop, January 200512 An Archive entry ecrystals.chem.soton.ac.uk

13. EPrints Workshop, January 200513 Access to the underlying data

14. EPrints Workshop, January 200514 Some metadata issues Using simple and qualified Dublin Core Additional chemical information in schema for harvesting e.g. empirical formula Schema contains International Chemical Identifier (InChI) Links to all datasets associated with an experiment Links to individual datasets within an experiment Links to EPrints (and other published literature) derived from the data Using vocabularies specific to crystallography Engaging the broader scientific community to ensure different schemas are compliant and standards can emerge

18. EPrints Workshop, January 200518 Embedded in a science portal

19. EPrints Workshop, January 200519 Current situation Version 2.0 eBank metadata schema Pilot institutional e-data repository for harvesting (raw, derived, results data) using EPrints.org software Exports records as ebank_dc and oai_dc Validation of schema & discussion with International Union of Crystallography for final developments and wider deployment Pilot eBank UK aggregator service Developing search interface Version 1.0 Testing with PSIgate physical sciences portal – embedding eBank UK

20. EPrints Workshop, January 200520 What’s next? Progress towards generic metadata schemas Validation against other schema (CCLRC Model) Eprints.org software: allow for more generic scientific data and schemas? Metadata enhancement: keywords based on knowledge of keywords in related publications? Investigate identifiers: International Chemical Identifier Explore context sensitive linking Full embedding into chemical and crystallographic research and publishing e-Learning embedding and pedagogic evaluation Feasibility study in related domains

21. EPrints Workshop, January 200521 Breakout Session? Describing non ‘Dublin Core’ terms  Qualified Dublin Core  Complex object formats: METS vs MPEG-21 DIDL  Set & Friends containers Compliance between schemas  One generic schema  Develop multiple schemas Rights  Use / reuse  Publisher Linking & aggregating  DOI  Keyword ontologies  Identifiers  Context sensitive linking
