Resource

A Resource is defined as:

An individual file or other form of data. Resources can be fully informationally equivalent, such as CSV and JSON serializations of the same data. Resources can also have different levels of fidelity, such as a CSV file and a graphical representation of the data within the file. Resources can also differ in other aspects, such as the temporal coverage of each resource.

Each dataset can have many associated resources.

Properties 

Title	Description	Type	Format	Required
`id`		string		Required
Resource identifier	A locally unique identifier for this resource.
`title`		string		Required
Resource title	A title for this resource.
`description`		string		Required
Resource description	A description for this resource.
`access_url`		string	iri
Access Url	A web address that gives access to this resource, e.g. a webpage through which a user can request access by completing a form.
`download_url`		string
Download Url	The web address this resource can be downloaded from in the given `.media_type` or `.format`.
`media_type`		string
Media type	The IANA media type that describes the format of the resource, from the open media_type codelist. The codelist provides human-readable titles for the media types. This field should be used when the IANA media type of the resource is known. If the media type of the resource is not known, an alternative label or description for the format may be provided in `.format`.
`format`		string
Format	The format of the resource, if the IANA media type of the resource is not known. Otherwise, `.media_type` should be used instead. If the resource represents an API via which the dataset is available, `.format` should be set to “API”. For more information, see how to describe an API.
`conforms_to`		string
Conforms to	An established standard to which the described resource conforms, from the open conforms_to codelist. The codelist provides human-readable titles for the media types. If the standard is not covered by the codelist, use of an HTTP URI is recommended.
`spatial`		object
Spatial coverage	The geographical area covered by the resource. If specified using coordinates, the use of `.bbox` is recommended over `.geometry` or `.centroid`. For more information, refer to spatial and temporal properties. See Spatial coverage
`spatial_resolution`		number
Spatial resolution	The minimum spatial separation resolvable in this resource, measured in meters. For more information, refer to spatial and temporal properties.
`spatial_aggregation`		string
Spatial aggregation	The fundamental spatial unit or geometric container used to organise, summarise, or ‘bin’ the data within this resource. This describes whether the data is unaggregated (e.g., individual building footprints or asset points), or aggregated into standardised administrative divisions (e.g., municipalities), hydrological units (e.g., catchments), or calculated geometric grids (e.g., hexagons or square gridcells).
`coordinate_system`		string
Coordinate reference system	An identifier string for the coordinate reference system (CRS) used in this resource. The CRS must be identified by a code issued by either EPSG or ESRI. The identifier string format is {authority}:{code}, e.g. EPSG:4326. https://epsg.io/ provides a searchable database of EPSG and ESRI coordinate system codes.
`temporal`		object
Temporal coverage	The period of time covered by this resource.
`temporal/start`		string
Start	The start of the period. A date (YYYY-MM-DD) is recommended. However, year-months (YYYY-MM) and years (YYYY) are supported.
`temporal/end`		string
End date	The end of the period. A date (YYYY-MM-DD) is recommended. However, year-months (YYYY-MM) and years (YYYY) are supported.
`temporal/duration`		string	duration
Duration	The duration of the period in ISO 8601 duration format, e.g. ‘P50Y’ for 50 years
`temporal/central_year`		integer
Central year	The central or representative year as a single point in time rather than a period (e.g., ‘2050’ representing the period 2040-2060). Use this instead of start/end when data represents conditions centered on a specific year.
`temporal_resolution`		string	duration
Temporal resolution	The minimum period of time resolvable in this resource, in ISO8601 duration format.
`baseline_period`		object
Baseline period	The baseline or reference period on which a forecast or projection is based.
`baseline_period/start`		string
Start	The start of the period. A date (YYYY-MM-DD) is recommended. However, year-months (YYYY-MM) and years (YYYY) are supported.
`baseline_period/end`		string
End date	The end of the period. A date (YYYY-MM-DD) is recommended. However, year-months (YYYY-MM) and years (YYYY) are supported.
`baseline_period/duration`		string	duration
Duration	The duration of the period in ISO 8601 duration format, e.g. ‘P50Y’ for 50 years
`baseline_period/central_year`		integer
Central year	The central or representative year as a single point in time rather than a period (e.g., ‘2050’ representing the period 2040-2060). Use this instead of start/end when data represents conditions centered on a specific year.
`climate`		object
Climate	Information about climate scenarios and models used to create the dataset.
`climate/model`		string
Climate model	The name or identifier of the climate model used to produce this resource
`climate/scenario`		string
Climate scenario	The climate scenario under which the data was produced, from the closed climate_scenario codelist.
`climate/percentile`		number
Percentile	The percentile of the climate model or model ensemble output represented in this resource, expressed as a number between 0 and 100. For example, 50 indicates the median (50th percentile) of the ensemble.

Spatial coverage 

Title	Description	Type	Format	Required
`scale`		string
Spatial scale	The spatial scale of the geographical area, from the closed spatial scale codelist.
`countries`		array[string]
Countries	The countries covered by the geographical area, from the closed country codelist.
`gazetteer_entries`		array[Gazetteer entry]
Gazetteer entries	Entries from geographical indices or directories describing the geographical area. This field should be used to describe sub-national coverage. Use of ISO 3166-2 is recommended.
`gazetteer_entries/0/id`		string		Required
Gazetteer entry identifier	An identifier drawn from the gazetteer identified in `.scheme`.
`gazetteer_entries/0/scheme`		string
Scheme	The gazetteer from which the entry is drawn, from the open location gazetteers codelist.
`gazetteer_entries/0/description`		string
Description	A description for the gazetteer entry.
`gazetteer_entries/0/uri`		string	iri
Uniform resource locator	A URI for the gazetteer entry.
`bbox`		array[number]
Bounding box	A geographic bounding box delimiting the geographical area. This field is an array of numbers. It must contain exactly four numbers with the first two numbers being the longitude and latitude of the most southwesterly point and the second two numbers being the longitude and latitude of the most northeasterly point. Coordinates must be specified using the World Geodetic System 1984 (WGS 84) datum, with longitude and latitude units of decimal degrees. This is equivalent to the coordinate reference system identified by the Open Geospatial Consortium URN urn:ogc:def:crs:OGC::CRS84.
`centroid`		array[number]
Centroid	The coordinates of the centre of the geographical area. This field is an array of numbers. It must contain exactly two numbers with longitude (easting) first and latitude (northing) second. Coordinates must be specified using the World Geodetic System 1984 (WGS 84) datum, with longitude and latitude units of decimal degrees. This is equivalent to the coordinate reference system identified by the Open Geospatial Consortium URN urn:ogc:def:crs:OGC::CRS84.
