Hi Luca,<br>
<br>
Thank you for your reply. First off, you are right that I meant
DescribeProcess. My mind is ajumble with WxS soup. It's easy to
get mixed up!<br>
<br>
I have a test service, implemented in pyWPS. If I make the
following request:<br>
<br>
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
<a
href="http://wps.iguess.tudor.lu/cgi-bin/pywps.cgi?SERVICE=WPS&VERSION=1.0.0&REQUEST=DescribeProcess&identifier=test_rand_map">http://wps.iguess.tudor.lu/cgi-bin/pywps.cgi?SERVICE=WPS&VERSION=1.0.0&REQUEST=DescribeProcess&identifier=test_rand_map</a><br>
<br>
I get back the following XML (excerpted):<br>
<br>
<div class="de1"><span class="sc3"><span class="re1"><Output<span
class="re2">></span></span></span></div>
<div class="de2"><span class="sc3"><span class="re1"><ows:Identifier<span

<div class="de1"><span class="sc3"><span class="re1"><ows:Title<span

output.<span class="sc3"><span class="re1"></ows:Title<span

<div class="de2"><span class="sc3"><span class="re1"><LiteralOutput<span

<div class="de2"><span class="sc3"><span class="re1"></LiteralOutput<span
class="re2">></span></span></span></div>
<div class="de1"><span class="sc3"><span class="re1"></Output<span
class="re2">></span></span></span></div>
<br>
A copy of the full output is available here:<br>
<br>
<a class="moz-txt-link-freetext" href="http://pastebin.com/JFB603TD">http://pastebin.com/JFB603TD</a><br>
<br>
This would suggest either a problem with pyWPS or owslib.<br>

<pre wrap="">Hi Chris,
it's been a while since I used the WPS client, so I might be totally wrong here, but...
First of all, are you referring to the output of a WPS DescribeProcess request (not "DescribeCoverage") ? If so, I think the output contains "LiteralData" elements, not "LiteralOutput", for example you can run the following request straight out of the OWSlib package (see below). I don't see any "LiteralOutput" tag... But off course I could be wrong, in which case can you send an example request and response ?
thanks a lot,
Luca

Subject: [owslib-users] Bug in owslib?
Hello,
I sent this query to the owslib-devel list a few weeks ago, and got
no response. I'm trying again here. I've fixed this in my local
copy of owslib, but want some reaffirmation that it is actually a
bug, and that my fix makes sense.
Thanks,
Chris
-------------------
I found what might be a bug in owslib, and want to confirm it.
Fortunately, if I am correct, it is a trivial fix.
So this is the issue:
I *think* that when parsing the results
of a WPS DescribeCoverage request, literal outputs are included in
the LiteralOutput tag. owslib seems to be looking for the
LiteralData tag, which is used in the input.
So the fix would be to replace
self._parseLiteralData(outputElement, 'LiteralData')
with
self._parseLiteralData(outputElement, 'LiteralOutput')
in wps.py, line c. 979.
I can be more specific if there is consensus that this is indeed a
problem.
Thanks!
Chris
