  1. EDMED and EDIOS Roy Lowry, Karen Vickers (Technical) Lesley Rickards, Liz Bradshaw (Content) British Oceanographic Data Centre

  2. European Directory of Marine Environmental Data (EDMED) • “Discovery” metadata • Comprehensive reference to marine data sets and collections in Europe • Over 3300 data sets • 700 data holding laboratories • From 30 countries bordering European seas, and 2 international organisations • On-line query & browse • Simple or advanced query interface to specify a combination of search criteria

  3. EDMED Status – June 2006 Number of Data Set Descriptions supplied by each Collating Centre

  4. EDMED Status – June 2006 • All Access database EDMEDs received during Sea-Search have been checked and loaded to the master database • Work continuing with France, Ireland and Belgium (and Germany) for XML import and export; problems include use of uncontrolled vocabularies • Current mechanisms for updating EDMED are: 1. Microsoft Access databases • These have been distributed for new entries and updates except for newest partners • Contact: Liz Bradshaw (elizb@bodc.ac.uk) 2. XML files • Further information available on request • Contact: Karen Vickers (kar@bodc.ac.uk)

  5. European Directory of the Ocean-observing System (EDIOS) • Initiative of the European Global Ocean Observing System (EuroGOOS) • Regular repeated measurements • On-line searchable directory of observing, measuring, and monitoring systems • Over 10,000 observation entries • Links to on-line real-time and archive data • Tool to aid design of observing systems

  6. EDIOS Status – June 2006 Number of observing sites by parameter group

  7. EDIOS Status – June 2006 • EDIOS project ran from 2001 – 2004 • Input was via a mixture of Metadata Input Forms (MIFs), spreadsheets and database export files • Five regional coordinators collected and collated input and passed to BODC • Input supplied by 30 countries • Front-end query and map interface designed by MARIS • Content review underway • Redesign of database underway

  8. Problems with EDIOS • Data model flawed (Observing Programmes should have at least one Data Series) and over-complicated relational database difficult to both populate and use • Set up with its own local controlled vocabularies with weak content governance • Population mechanism based on Word forms weakly mapped to the schema

  9. Proposed Improvements to EDIOS • Sort out the data model and simplify the schema • Harmonise vocabularies with CDI, EDMED and the rest of the world. Working towards interoperability • Enhance both technical and content governance of vocabularies in SeaDataNet • Develop a sandbox-based on-line content entry and maintenance tool

  10. What Are We Doing? • Development specification under review • Use this to produce a revised data model and relational schema document (June) • Vocabulary harmonisation (July) • Build new schema (August) • Sort out issues with existing population (to end of year and beyond) • Build population tools (August-September)
