From suzana.barreto at envsys.co.uk Mon Nov 12 07:36:16 2018 From: suzana.barreto at envsys.co.uk (Suzana Barreto) Date: Mon, 12 Nov 2018 15:36:16 +0000 Subject: [OWSLib-users] Process Chaining Message-ID: Hi All, I have been trying to chain process requests using OWSLib and PyWPS server but have not been too successful. I have been able to fire separate requests off in order using the output from one as input to the next but I would specifically like to be able to chain them through embedding. I have attempted to use the WPSExecution object to build my requests by embedding a request as the input of the second request but have found that the xml for the embedded request ends up being escaped and malformed. Looking at the ComplexDataInput class, I notice that this can only be a ComplexReference type or a ComplexDataRaw type but it appears that it always evaluates to the reference type so my embedded query is then escaped and appears in the HREF tag of the input data. I have also tried to create a manual xml document but cannot find the correct XML element that identifies the embedded request. So what I am asking is if anyone knows or can point me to an example showing how chaining is achieved, or alternatively the correct XML structure for an embedded / chained request.
