Number of Data Set Descriptions supplied by each Collating Centre

• 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)

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

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

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

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)
