  1. CODATA / TDWG / BioCASEUnit Profile Introduction to The XML Schema Version 1.37 Neil Thomson, The Natural History Museum, London Campinas October 2002

  2. Origins • Initiated by CODATA/TDWG in June 2001 • Chosen for additional use by BioCASE in June 2002, rather than creating a separate profile • Based on ABCD, current version is called CTBUP v1.37 • Brief introduction followed by walkthrough in XMLSpy Campinas October 2002

  3. Principles maintained • Strong typing used • Meaningful element names used • Compatibility with existing standards • Rich data for “who / what / where / when” with emphasis on organism names, places and time • Extensible • Policy on optionality • Use of attributes Campinas October 2002

  4. Major changes • Conversion from DTD to Schema – better for data-centric documents and can use typing • Darwin Core 2 compatible • Removal of geology elements (for current use) • Reduction of element set • Recursion eliminated • Pruning e.g. of images and references • Addition of structured annotation elements Campinas October 2002

  6. The Schema will: • Deliver unit-oriented data from databases (sources) to web-based services that will integrate the data from different sources • Provide a semantic definition of the data items needed for that purpose • Require identification of access points, through which the data may be queried Campinas October 2002

  7. The Schema does not: • Serve to define databases • Include taxon-based information • Include ecological data, except for the description of a gathering site or observation site Campinas October 2002

  8. RfC - Request for Comment • Version 1.36 flattened into Excel file • 11 extracts forwarded to volunteers • Some suggestions incorporated into v1.37 for this meeting • Schema is available at the TDWG Website http://www.bgbm.fu-berlin.de/tdwg/CODATA/Schema/ Campinas October 2002
