  24. Event tables management in AMDA Current status: • Time (or Event) Tables are collections of times when ‘something’ happens or time spans when some conditions are true. • Currently produced and managed « manually » by the scientists for their own use or for a community of users. • AMDA is increasing the possibilities of these tables : it provides a generic tool to create, manage and share these objects • How to generate Time tables with AMDA : • With the search tool based on mathematical criteria applied to the contents of the data • With the visual search tool • AMDA can ingest Time Tables : • Coming from statistical studies ( e.g magnetopause crossing lists ) • Produced by users HDMC VxO SPASE 10-12 June 2008

  30. Event tables : Next step • Exchange of standardized time tables between data centres, services, tools. • A complete description of a time table may be difficult : • Description of the data source • Description of search criteria : visual, mathematical • Description of the methods used (models, …) • Use Spase « catalog » resource ? • A project started (early 2008) : Exchange of TT between CAA QSAS CL and AMDA HDMC VxO SPASE 10-12 June 2008
