Foil 15 XML for GEM ?

From Distributed Objects for GEM General Earthquake Simulation Project Meeting JPL Pasadena -- April 22 99. by Geoffrey C. Fox


XML is the web distributed object model or
  • XML is ASCII format for database export or
  • XML is universal object serialization technology
If not XML, would need to design lots of database schema, "CORBA/Java Interface Definitions ..."
XML is just a generalized HTML (or a simplified SGML)
<faultsegment id="park101" date="Jan 1 2000" author="" source= .. Lat1="" lat2="" long1="" long2="" depth="" ..>Part of the Parkfield System</faultsegment> <stress type ="prediction" fault="park101" source="Multipole Simulation">(2.3,7.7,-7.2)</stress>
There are/will be wonderful tools to produce access edit and display XML
Need to design GEM specific tags
