[webservices] Beta release of ws-station, including a new StationXML schema

[Yazan Suleiman]

Hello webservice users,

The DMC has released a beta version of our ws-station service and would appreciate any level of feedback.  The changes in this release include an update to the StationXML schema making the results NOT backwards compatible with the current service (more details below).  Also introduced are new time range selection parameters.

We anticipate this version replacing the current service on April 2nd.  After which any clients depending on the (few) changes in the schema will not work correctly.  In particular, the beta Java IRIS-WS Library (and the related MATLAB support) will stop working properly.  We plan on releasing new versions of the IRIS-WS Library at the same time to match this update in the ws-station service.

regards,
Web services team


Details of the changes include:

1) New starttime and endtime parameters, the timewindow parameter is now deprecated as these two parameters provide the same and much more functionality.  In addition to allowing start and end times to be specified independently these new parameters allow time to be specified (as opposed to only a date).  See the service help for details.

2) The service has been updated to the latest StationXML schema:
http://www.data.scec.org/xml/station/20120307/station.xsd

The relavent changes for ws-station users are as follows:

A) The SEED "site name" is now placed in the <Name> element inside the <Site> tag.
before:
<Site>
 <Country>Ankober, Ethiopia (near Debra Birhan)</Country>
</Site>

after:
<Site>
 <Name>Ankober, Ethiopia (near Debra Birhan)</Name>
</Site>

This rearrangement also removes the <Name> element previously found inside of a the Channel <Epoch> tag.

B) Removed the swap_order attributes from the Station <Epoch> tag
<StationEpoch> instead of <StationEpoch swap_order_16="BIG_ENDIAN" swap_order_32="BIG_ENDIAN">

C) Removed stage 0 response structure, this is replaced by the 'Channel' 'InstrumentSensitivity structure'.

D) Added new elements describing <PolesZeros> and <Coefficients>: <PzTransferFunctionType> and <CfTransferFunctionType>

E) Replaced <GainUnits> with <SensitivityUnits> inside of <StageSensitivity> tag of a response cascade.
