The InspireFeatureDownload
and InspirePredefinedDatasetDownload
listed as supported extensions on http://www.geoportal.lt/inspire-services/rest/services/INSPIRE/Transport_networks_CommonTransportElements/MapServer does suggest some vector download should be possible.
The ArcGIS documentation on creating such services Create the feature download service tells us that indeed it is/should be a WFS 2.0.0.
There is a section Enable direct access
that tells us:
This option enables the ability to access data directly through the standard WFS 2.0.0 getFeature operation without going through the stored query configured by the administrator. This option is disabled by default.
So it possible that the service has not been configured as direct access.
The page Use the INSPIRE Feature Download service suggests to us that the following URL should respond as a WFS
http://www.geoportal.lt/inspire-services/rest/services/INSPIRE/Transport_networks_CommonTransportElements/MapServer/exts/InspireFeatureDownload/service?REQUEST=GetCapabilities&SERVICE=WFS
but it doesn't...
I get a form, but it should be an XML response. It would probably be worth contacting the data providers directly to check if this is intentional.
