Hi Michael, I don't think this has been widely used (not many server implementations).
The test for whether it's a multipart mime or not is pretty feeble. Maybe this is the problem?:

Dear owslib-users, wonder how the reading of coverage data from WCS 1.1.0/1.1.1 providers is working? I get the results from the WCS in the multipart mime format,or at least I think I do ;-) When issuing the getCoverage URL in the browser, the xml section is displayed and the tif is offered for download. When trying the same in python/owslib, the getCoverage result is not recognized as a multipart file and so the result as a whole is saved by the wcsdecoder. That's (some of) the content of the saved file: --------- --_boundary_gks93dbq MIME-Version: 1.0 Content-type: text/xml Content-ID: urn:ogc:wcs:1.1:coverages <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <owcs:Coverages xmlns:ows="http://www.opengis.net/ows"; xmlns:owcs="http://www.opengis.net/wcs/1.1/ows"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns="http://www.opengis.net/wcs/1.1"; xmlns:gml="http://www.opengis.net/gml"; xmlns:smil20="http://www.w3.org/2001/SMIL20/"; xmlns:smil20lan="http://www.w3.org/2001/SMIL20/Language"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/wcs/1.1/ows http://schemas.opengis.net/wcs/1.1.0/owcsAll.xsd http://www.opengis.net/wcs/1.1 http://schemas.opengis.net/wcs/1.1.0/wcsAll.xsd";> <owcs:Coverage> <owcs:Identifier>wc_30s_tmax_12</owcs:Identifier> <owcs:Reference xsi:type="owcs:AbstractReferenceBaseType" xlink:arcrole="urn:ogc:def:role:WCS:1.1:coverage" xlink:href="cid:wc_30s_tmax_12.bil"/> </owcs:Coverage> </owcs:Coverages> --_boundary_gks93dbq MIME-Version: 1.0 Content-type: image/tiff Content-ID: wc_30s_tmax_12.bil [...] ------------------ It looks like a multipart file, but I thought there should be a header, but it is not there. When inspecting the whole thing it returns text/plain as the contentType... Hmm, anyone succeeded in using the wcsdecoder? Thanks, Michael
