### stationXML

A network source that makes the metadata loaded from a StationXML file available to SOD. While a local file could be used, the more useful way is to access the ws-station web service at the IRIS DMC, http://www.iris.edu/ws/ws-station. SOD can download the stationXML automaticially and reconnect to periodically get updates. For a full SOD run (that retrieves waveforms) SOD will automatically set the level in the IRIS url as needed, but adding other qualifiers to limit the request size will help speed the queries. You may need to escape the ampersand with & due to the fact that a SOD recipe is XML and so the parser will signal an error for a unescaped ampersand.

### This ingredient is deprecated!

While it will continue to be supported by sod, there is now a better way. This is deprecated in favor of the new fdsnStation source.

### Example

    <stationXML>
        <url>http://www.iris.edu/ws/station/query?net=II&sta=AAK&chan=BHZ,BHN,BHE,BH1,BH2&loc=00,--&level=chan</url>
        <refreshInterval>
            <unit>DAY</unit>
            <value>10</value>
        </refreshInterval>
    </stationXML>

### This consists of

<stationXML>

<url>Any text</url>
<refreshInterval> optional
</stationXML>
