               This can be used for general matching relations like "skos:exactMatch", "skos:closeMatch", etc. or for specific features like spatial matching with geo data
               (e.g. containment search with "schema:containsPlace" etc.) or custom matching on date fields (e.g. services supporting the [[EDTF]] specification could use "EDTF:Level-0" etc.
