Converting Catalogs to GML/XML
Format
Catalogs to GML/XML Format


Downloaded catalogs are converted to
GML format.
This allows us to

Have a common data format
 Use native XML Databases like Xindice or
Sleepycat.

Add GML Data to XML Database
XML Databases
The System supports both Xindice and
Berkeley XML DB (Sleepycat).
 We have Web Service interfaces to
manage the XML DBs.

Query Construction for XML DB
Search
Queries for both GPS and Earthquake
catalog searches are generated by our
system.
 Sample Query:


/GPSDataContainer/GPSData[Site[text()='7ODM'] and
Component[text()='LAT'] and Date[@DecimalYear>=2002] and
Date[@DecimalYear<2004] and
Estimate[text()>=0] and
Estimate[text()<=3.2]]
