Currently the fields/items of the layers (defined under map file
METADATA KML_INCLUDE_ITEMS) are exported to a KML tag "<description>"
and inserted as HTML table. While this is of course possible, a
cleander way would be how GDAL/OGR exports the attributes:
GDAL/OGR uses the tag <ExtendedData> and places the attribute values
in <SimpleData> tags, like
<Placemark>
...
<ExtendedData><SchemaData schemaUrl="#cities">
<SimpleData name="Name">Berlin</SimpleData>
<SimpleData name="GEONAMEID">3899412</SimpleData>
<SimpleData name="ISO2_CODE">DE</SimpleData>
<ExtendedData>
This leads to a much better display in Google Earth.
I have added this in http://trac.osgeo.org/mapserver/ticket/3728 and
possibly address it before 6.0 or shortly after.
In addition to the KML_INCLUDE_ITEMS, another possibility to define a
field/item used in KML for the <name> tag would be useful, like OGR
allows this via the NameField option. So maybe a METADATA definition
like KML_NAME_FIELD could do this.
The is added to the current svn and will be available for beta2 (ticket
<http://trac.osgeo.org/mapserver/ticket/3728>). The docs are also
updated. Note that the metedata is KML_NAME_ITEM to follow other metada
names used.
