Each collection is accessible via one or more OGC API set of specifications, for which a link to relevant accessible resources, e.g. /collections/{collectionId}/(items, coverage, map, tiles...) is provided, with the corresponding relation type, as well as key information about the collection. This information includes: * a local identifier for the collection that is unique for the dataset; * a list of coordinate reference systems (CRS) in which data may be returned by the server. The first CRS is the default coordinate reference system (the default is always WGS 84 with axis order longitude/latitude); * an optional title and description for the collection; * an optional extent that can be used to provide an indication of the spatial and temporal extent of the collection - typically derived from the data; * for collections accessible via the Features or Records API, an optional indicator about the type of the items in the collection (the default value, if the indicator is not provided, is ''feature'').' content: application/json: schema: $ref: '#/components/schemas/collections' example: links: - href: http://data.example.org/collections.json rel: self type: application/json title: this document - href: http://data.example.org/collections.html rel: alternate type: text/html title: this document as HTML - href: http://schemas.example.org/1.0/buildings.xsd rel: describedby type: application/xml title: GML application schema for Acme Corporation building data - href: http://download.example.org/buildings.gpkg rel: enclosure type: application/geopackage+sqlite3 title: Bulk download (GeoPackage) length: 472546 collections: - id: buildings title: Buildings description: Buildings in the city of Bonn. extent: spatial: bbox: - - 7.01 - 50.63 - 7.22 - 50.78 temporal: interval: - - '2010-02-15T12:34:56Z' - null links: - href: http://data.example.org/collections/buildings/items rel: items type: application/geo+json title: Buildings - href: http://data.example.org/collections/buildings/items.html rel: items type: text/html title: Buildings - href: https://creativecommons.org/publicdomain/zero/1.0/ rel: license type: text/html title: CC0-1.0 - href: https://creativecommons.org/publicdomain/zero/1.0/rdf rel: license type: application/rdf+xml title: CC0-1.0 text/html: schema: type: string Collection_2: description: 'Information about a particular collection of (mostly geospatial) data available from this API.
