[webservices] New version of the IRIS Java web services library: 2.0.2

[Anthony Lomax]

Hello,

The European High Schools are using directly the IRIS DMC Web Services 
for data hosted at IRIS and local implementations of a subset of these 
services for other data.

One local tool we have developed uses an iris type availability ws to 
check for data available around the origin time of an earthquake for a 
list of networks/stations.  The old iris availability service 
(deprecated) returns a compact response (even in XML!) for such a 
request, e.g.

    http://www.iris.edu/ws/availability/query?&starttime=2013-01-01T00:00:00&endtime=2013-01-01T01:00:00&sta=CMB&cha=BHZ&output=xml

    <StaMessage><Source>IRIS-DMC</Source><SentDate>2013-07-03T07:31:57</SentDate><Station
    net_code="BK"
    sta_code="CMB"><Lat>38.03455</Lat><Lon>-120.38651</Lon><Elevation>697.0</Elevation><Channel
    chan_code="BHZ" loc_code="00">
    <Availability><Extent start="2013-01-01T00:00:00"
    end="2013-01-01T01:00:00"/></Availability>
    </Channel></Station></StaMessage>

while the replacement , e.g.

    service.iris.edu/fdsnws/station/1/query?starttime=2013-01-01T00:00:00&endtime=2013-01-01T01:00:00&sta=CMB&cha=BHZ&level=channel&includeavailability=true

returns a monster response (attached!) including:

    <DataAvailability><Extent start="2010-12-17T19:52:43"
    end="2013-07-02T12:00:00"/></DataAvailability>

Note that besides the huge size of the response (we need to make 
multiple requests for a list of stations), the <DataAvailability><Extent 
in the two responses are different - the first confirms a data window 
within our requested time span (exactly the response we want), while the 
second seems to present to total time of data available, which we would 
have to further process to confirm that our time window of interest is 
available.

Is all of the above behaviour and the differences between the two 
responses correct?  Is there any way or any plans to get the more 
compact, old-style availability response?

Thanks,

Best regards to all,

Anthony
