I'm currently working on the GetCapabilties request for a CSW which
requires that I set a FiltersCapabilities block in the XML. I was all going
well until I tried validating the output and discovered what look like
issues in the GeoTools XML encoding of the Filter spec. Before I file bugs
and work on a fix I thought I should check I'm really understanding this
correctly.
First I'm using
http://schemas.opengis.net/filter/1.1.0/filterCapabilities.xsd as the
reference schema - which should match out filter factory according to the
headers. I'm setting the encoder up using the following:
try {
final Encoder encoder = new Encoder(conf);
encoder.setIndenting(true);
encoder.setNamespaceAware(true);
encoder.getNamespaces().declarePrefix("ows", OWS.NAMESPACE);
encoder.getNamespaces().declarePrefix("ogc", OGC.NAMESPACE);
encoder.getNamespaces().declarePrefix("gml", GML.NAMESPACE);
encoder.getNamespaces().declarePrefix("xlink", XLINK.NAMESPACE);
encoder.setSchemaLocation(OWS.NAMESPACE, SCHEMALOCATION +
"ows/1.0.0/owsCommon.xsd");
encoder.setSchemaLocation(OGC.NAMESPACE,
"http://schemas.opengis.net/filter/1.1.0/filterCapabilities.xsd";);
encoder.setSchemaLocation(CSW.NAMESPACE, SCHEMALOCATION +
"csw/2.0.2/CSW-discovery.xsd");
encoder.setSchemaLocation(XLINK.NAMESPACE, SCHEMALOCATION +
"xlink/1.0.0/xlinks.xsd");
// encoder.getNamespaces().declarePrefix("fes", FES.NAMESPACE);
encoder.encode(resp, CSW.Capabilities, out);
} catch (final IOException e) {
LOGGER.debug(e.getMessage(), e);
throw new EBRIMException("Problem encoding the response", e);
}
This then gives the wrong names for PropertyIsGreaterThanOrEqualTo.NAME
and PropertyIsLessThanOrEqualTo.NAME both of which have an Or in them but
shouldn't have.
ArithmeticOperators contains a empty Functions element which it shouldn't
(it's a choice with minOccurs=1) so if there are no functions then there
should be no Functions element at all. (interestingly I also noticed that
if you use the copy constructor on an ArithmeticOperatorImpl - you get a
different answer
(<ogc:Functions><ogc:FunctionNames></ogc:FunctionNames></ogc:Functions>)
which is also wrong.
With no ID filters set you get <ogc:Id_Capabilities /> which is invalid for
the same reason.
Am I right that these are broken?
