• GetCapabilities = strojově (a lidsky) čitelná metadata
obsahu OGC služby
• Obsahují číslo verze protokolu a musí odpovídat XML
DTD nebo schématu definovanému pro danou verzi
• Odezva se liší na základě verze služby (výchozí
verze)
• Obvykle jsou vyžadovány parametry:
– REQUEST (REQUEST=GetCapabilities)
– SERVICE
– VERSION (volitelně)
– FORMAT (volitelně)

Laboratoř geoinformatiky a kartografie
Základní principy – GetCapabilities odezva
• Obvykle XML dokument obsahující metadata
formátovaná podle XML schématu daného OGC
specifikací:
– definice povinných a volitelných částí
– formátování obsahu
• Jmenný prostor (namespace) podle OGC specifikace
– např. http://www.opengis.net/wms
• Elementy <name> a <title>
– <name> textový řetězec pro strojovou komunikaci
– <title> „lidsky“ čitelné označení
2
Laboratoř geoinformatiky a kartografie
Struktura GetCapabilities odezvy
• První část začíná elementem <Service>
– obecná metadata o serveru jako celku
– musí obsahovat Name, Title, Online Resource URL
• volitelně pak Abstract, Keyword List, Contact
Information, Fees, Access Constraints, další specifické
vlastnosti (jako např. limity počtu vrstev či výsledné
velikosti map u WMS aj.)
• Druhá část začíná elementem <Capability>
– operace podporované serverem, výstupní formáty pro
tyto operace, URL prefix pro každou operaci
• Z DCP je podporováno pouze HTTP
