Description

The rules generated by QGIS contain schema invalid output, here is a sample:

        <se:Rule>
          <se:Name>159.0550 - 137771.0580</se:Name>
          <se:Description>159.0550 - 137771.0580</se:Description>
          ...
        </se:Rule>

The Description element is defined, in SE 1.1, as:

<xsd:complexType name="DescriptionType">
         <xsd:sequence>
            <xsd:element name="Title" type="xsd:string" minOccurs="0"/>
            <xsd:element name="Abstract" type="xsd:string" minOccurs="0"/>
        </xsd:sequence>
    </xsd:complexType>

So the generated markup should actually look like the following:

       <se:Rule>
          <se:Name>159.0550 - 137771.0580</se:Name>
          <se:Description>
             <se:Title>159.0550 - 137771.0580</se:Title>
          </se:Description>
          ...
        </se:Rule>

please give a try to qgis master, there have been fixes ablut SLD support after the relase of qgis 1.8

#2 Updated by Andrea Aime about 8 years ago

Btw, this is on Ubuntu 10.04, QGIS 1.8.0 - Lisboa, coming from the UbuntuGIS apt

there is a repo for Ubuntu that allows to install qgis-master, see the qgis download page.

#4 Updated by Andrea Aime about 8 years ago

I've just found the same behavior on the Windows release of QGIS 1.8.0 Lisboa, so it's not OS or package specific

can you try qgis-master under Windows? it is easy to install with osgeo4w.

Ok, with QGis master things look better, the document is valid, but it will still won't work 100% good with SLD based systems:

<se:Rule>
          <se:Name>159.0550 - 137771.0580</se:Name>
          <se:Description>
            <se:Abstract>159.0550 - 137771.0580</se:Abstract>
          </se:Description>
          <ogc:Filter>
            <ogc:And>
              <ogc:PropertyIsGreaterThan>
                <ogc:PropertyName>LAND_KM</ogc:PropertyName>
                <ogc:Literal>159.055</ogc:Literal>
              </ogc:PropertyIsGreaterThan>
              <ogc:PropertyIsLessThanOrEqualTo>
                <ogc:PropertyName>LAND_KM</ogc:PropertyName>
                <ogc:Literal>137771</ogc:Literal>
              </ogc:PropertyIsLessThanOrEqualTo>
            </ogc:And>
          </ogc:Filter>
          <se:PolygonSymbolizer>
            <se:Fill>
              <se:SvgParameter name="fill">#f7fbff</se:SvgParameter>
            </se:Fill>
            <se:Stroke>
              <se:SvgParameter name="stroke">#000000</se:SvgParameter>
              <se:SvgParameter name="stroke-width">0.26</se:SvgParameter>
            </se:Stroke>
          </se:PolygonSymbolizer>
        </se:Rule>

The Description tag is now valid, but in order to support proper legend generations in GeoServer it should use Title, not Abstract (which is meant for a verbose description of the style, as opposed to the title, which is meant to be concise and usable in legends)

I agree, I'm changing it.
