• Infrastructure for Spatial Information
in Europe - initiative launched by
the European Commission for
solving interoperability issues for
geospatial data
http://inspire.jrc.ec.europa.eu

publishing spatial data to the web
• Fast, flexible, reliable, and highly integratable
• Support of various OGC standards: WMS, WFS,
WCS, SLD, SOS, etc.

• 16+ active developers; ~300k LoC;
~77 man‑years; IRC #mapserver 30+
• Latest highlights: MapCache, TinyOWS, Github

6. INSPIRE View Service in MapServer
• Available with MapServer 6.2 release
• WMS 1.3.0
• Based on Technical Guidance in version 3.0
• Documentation

7. Activation of INSPIRE support
• scenario 1: external metadata: "url"
• scenario 2: embedded metadata: "embed"
WEB
METADATA
"wms_inspire_capabilities" "url"
...
END
END

8. Multi-language support (1/3)
• Provisioning of all supported languages
• Values according to ISO 639-2/B
• First value is default language
WEB
METADATA
…
"wms_languages" "eng,ger,ita"
...
END
END

9. Multi-language support (2/3)
WEB
METADATA
"wms_title.eng" "Transport Network"
"wms_title.ger" "Verkehrsnetz"
"wms_abstract" "myabstract"
...
END
END
...&REQUEST=GetCapabilities&LANGUAGE=eng

10. Multi-language support (3/3)
• Run-time substitution (only CGI)
• DATA & CONNECTION metadata
LAYER
NAME TN.RoadTransportNetwork.RoadArea
DATA "road_%language%.shp"
...
END
...&REQUEST=GetMap&LANGUAGE=eng

11. INSPIRE specific metadata - Scenario 1
"wms_inspire_metadataurl_href" "http://..."
"wms_inspire_metadataurl_format"
"application/vnd.ogc.csw.capabilities.response_xml"
"wms_keywordlist_vocabulary" "ISO"
"wms_keywordlist_ISO_items" "infoMapAccessService"
"wms_fees" "conditions unknown"
"wms_accessconstraints" "None"
"wms_contactorganization" "MapServer"
"wms_contactposition" "owner"
...

12. INSPIRE specific metadata - Scenario 2
Additional metadata:
"wms_inspire_temporal_reference" "2012-05-22"
"wms_inspire_mpoc_name" "mympocname"
"wms_inspire_mpoc_email" "mympoc@e.mail"
"wms_inspire_metadatadate" "2012-05-22"
"wms_inspire_resourcelocator" "http://resource"
• Values are not validated
• Some metadata is hard-coded

13. Named group layers (1/2)
• Via wms_layer_group
• Arbitrary depth
• Named vs. Unnamed
• Supported in GetMap,
GetFeatureInfo, etc.
LAYER
NAME RoadArea
METADATA
"wms_layer_group" "/RoadTransportNetwork"
…

14. Named group layers (2/2)
MAP
NAME TN
…
LAYER unnamed
NAME RoadTransportNetwork
...
LAYER
NAME RoadArea
METADATA
"wms_layer_group" "/RoadTransportNetwork"
…
• Only TN and RoadArea can be requested
• RoadTransportNetwork only used for grouping
