[Geoserver-users] Problem with encoding of supported language in Geoserver 2.20.0 INSPIRE extension

[Elena G. <gri...@gm...>]

Hi all,

I am using the INSPIRE extension with Geoserver 2.20.0, to provide INSPIRE
services. I am testing the implementation with the INSPIRE validator (the
one provided by JRC along with a local installation).

I would like to know if anyone has noticed problematic behavior, as regards
the encoding of other supported languages.

Bellow I am describing the problem I noticed:

*Correct INSPIRE extended caps schema (TechnicalGuidance_ViewServices_v3.0
<https://inspire.ec.europa.eu/documents/Network_Services/TechnicalGuidance_ViewServices_v3.0.pdf>)*

<inspire_vs:ExtendedCapabilities>

<inspire_common:MetadataUrl xsi:type="inspire_common:resourceLocatorType">
<inspire_common:URL>http://discoveryService <http://discoveryservice/>
....</inspire_common:URL>
<
inspire_common:MediaType>application/vnd.ogc.csw….</inspire_common:MediaType>
</inspire_common:MetadataUrl>
<inspire_common:SupportedLanguages
xsi:type="inspire_common:supportedLanguagesType">
<inspire_common:DefaultLanguage>
<inspire_common:Language>dut</inspire_common:Language>
</inspire_common:DefaultLanguage>
<inspire_common:SupportedLanguage>
<inspire_common:Language>eng</inspire_common:Language>
</inspire_common:SupportedLanguage>
</inspire_common:SupportedLanguages>
<inspire_common:ResponseLanguage>
<inspire_common:Language>dut</inspire_common:Language>
</inspire_common:ResponseLanguage>
</inspire_vs:ExtendedCapabilities>

   1. *same default and supported language in wms INSPIRE extension
   configuration *

When the default and other supported language is the same, the capabilities
document omits the element
/../inspire_vs:ExtendedCapabilities/inspire_common:SupportedLanguages/inspire_common:SupportedLanguage.
Since the element is not mandatory, the INSPIRE validation is successful
(at least as regards the schema validation).

   1. *no other supported language*
   When no other supported language is selected, the element
   /../inspire_vs:ExtendedCapabilities/inspire_common:SupportedLanguages/inspire_common:SupportedLanguage
   is present in the capabilities document but it is not correctly encoded.

The child element
/../inspire_vs:ExtendedCapabilities/inspire_common:SupportedLanguages/inspire_common:SupportedLanguage/inspire_common:Language
is missing so the schema validation fails.

The INSPIRE validator returns the following message:

*Schema not valid: [org.xml.sax.SAXException: Fatal error:
org.xml.sax.SAXParseException; lineNumber: 110; columnNumber: 48;
cvc-complex-type.2.4.b: The content of element
'inspire_common:SupportedLanguage' is not complete. One of
'{"http://inspire.ec.europa.eu/schemas/common/1.0
<http://inspire.ec.europa.eu/schemas/common/1.0>":Language}' is expected.
Response did not validate against schema
'http://inspire.ec.europa.eu/schemas/inspire_vs/1.0/inspire_vs.xsd'
<http://inspire.ec.europa.eu/schemas/inspire_vs/1.0/inspire_vs.xsd'>.]*

   1. *different default and other supported languages*
   The desired configuration in our case is to provide different default
   and supported languages, using the i18n configuration for the
   internationalization of the capabilities response.

When this configuration is present, the capabilities response is again not
correctly according to the INSPIRE validator.

The relevant test fails for the schema validation. The error is
*Schema not valid: [org.xml.sax.SAXException: Fatal error:
org.xml.sax.SAXParseException; lineNumber: 110; columnNumber: 85;
cvc-complex-type.2.3: Element 'inspire_common:SupportedLanguage' cannot
have character [children], because the type's content type is element-only.
Response did not validate against schema 'http://inspire.ec.europa.eu/
<http://inspire.ec.europa.eu/schemas/inspire_vs/1.0/inspire_vs.xsd'>*

Note #1 <https://github.com/EOFarm/geoportal.ypen.gr/issues/1>: The i18n
configuration does not affect geoserver’s behavior regarding the inspire
extended caps.
Note #2 <https://github.com/EOFarm/geoportal.ypen.gr/issues/2>: The above
testing was made for the following virtual wms
http://beta.geoportal.ypen.gr/geoserver/aqd-wms/ows?service=wms&version=1.3.0&request=GetCapabilities
