StationEpoch duplicates
2011-11-14 18:05:12 - 2011-11-14 22:20:54
Hi. The query http://www.iris.edu/ws/station/query?updatedafter=2011-06-06&level=sta&net=ND&timewindow=2010-01-01,2500-12-12 returns multiple duplicates of the <StationEpoch> sections for each station. Makes my sync to a local copy procedure very slow... Thanks! -- John

Station web service: to Network, or not to Network?

flinn-engdahl region type
2011-11-10 22:38:28 - 2011-11-11 02:10:06
I think this is also invalid as the <type> is restricted to an enum of fixed strings, so appending the numerical region to it is invalid. That said, I think having the region number as opposed to just the text name is very valuable. Perhaps you could use the eventParameters_foreign-attributes or eventParameters_foreign-elements to add the number?

validation of quakeml from event web service
2011-11-10 21:23:25 - 2011-11-10 22:13:59
Hi I am having trouble validating the quakeml output from the event web service. Have you been able to validate it to make sure it matches the relaxng or xschema definitions of QuakeML? The first problem is that in the schema definition the top level <quakeml> element is in the "http://quakeml.org/xmlns/quakeml/1.2" namespace, while the <eventParameters> and all of the elements inside it are in the "http://quakeml.org/xmlns/bed/1.2" namespace. The output from the web service trys to put all o… [more]

defaults on event url builder
2011-11-08 19:10:41
Hi The defaults on the URL builder for the event web service are to get a whole years worth of events with no min magnitude. I would never be so dumb as to click on that link, or at least I won't admit to it! But if someone does then bad things start to happen like firefox locking up, fans turning on and general laptop unhappiness. I am guessing that your database is also probably not too happy about pulling every event from the last year out of the database and stuffing it into xml for no goo… [more]

event service revision history, names and bad links
2011-11-07 21:21:56
The revision history for the event service is somewhat empty, although I guess seeing that you are running version X.X is somewhat interesting! :) http://www.iris.edu/ws/doc/event_revisions.htm This page is also missing a few services, including the event one. http://www.iris.edu/ws/doc/ This page seem to not have style info associated with it. It also has a bad link in the breadcrumbs, pointing to /hq/ws instead of /ws. http://www.iris.edu/ws/flinnengdahl There appear to be two different na… [more]

quakeML schema
2011-11-07 19:08:03
Hi The QuakeML schema seems to be on a https site that has an invalid certificate (both no issuer chain and is expired). I know that I can bypass this and still get the schema file, but it is a little disturbing. It seems to me that the schema for something that is supposed to be an open standard that IRIS is supporting should be available in a more public and easily accessible way. In particular, this https with expired certificate makes it harder to write a client that will pull the schema f… [more]

stations and networks in StaMessage
2011-11-04 20:36:36
Hi Is there a reason to have both stations and networks directly in a StaMessage in StationXML? It adds some complexity to the parsing on the client side to have to deal with two cases. As the network element is really lightweight, with only the code attribute being required, so why not require all stations be inside Network elements? I am not sure having "naked stations" really buys much other than backwards compatibility, and so I would argue against it. Is there some other reason that I am … [more]
