[seek-dev] ecogrid query

[Matt Jones]

Hi David,

You can query using the existing ecogrid interfaces, but only against 
the metadata that is available for the data source.  By default, SRB 
doesn't have much contextual metadata.  I've talked with Raja about 
modifying SRB to accept an EML description of the data and load that 
into the extended metadata for the dataset, but that hasn't been done 
yet as far as I know.  Another option is to load EML metadata describing 
the data into the KNB metacat, and then point that at the data objects 
in the SRB.  Then, searching the EcoGrid will find metadata records in 
one system that point at data objects in abother system.  But you'd be 
able to search the much more comprehensive EML metadata.

If you have metadata you want to query, you can use the QueryBuilder to 
construct a query, but it is intended as a developer's tool for testing, 
not an end-user tool.  Steve Tekell is designing and implementing a 
web-based query app for EcoGrid targeted at scientists.  When finished, 
it will be installed as part of the SEEK web site.  Until then, Rod's 
tool and the commandline client are your options for submitting a query. 
  There is an extremely simple query tool prototype in Kepler, but right 
now it only searches the KNB Ecogrid node.
