Coverage

The property coverage describes a relationship between a resource and another resource which represents the extent or scope of the content of the first resource. This includes the spatial locations (a place name or geographic co-ordinates), temporal periods (a period label, a date or a date range), or jurisdictions (states, counties, or other administrative entities). If you want to make a destinction between the temporal or spatial character of the content use temporal or spatial.

Temporal

This property describes the relationship between a resource and another resource which represent the temporal characteristics of the intellectual content of the first resource expressed by period labels or date encoding. If you want to describe date of the lifecycle of a resource use the date properties.

Spatial

This property describes the relationship between a resource and another resource which represents spatial characteristics of the intellectual content of the first resource expressed by by geographic names, latitude/longitude, or other established georeferencing.

Guidelines for describing the coverage, spatial or temporal character of a resource

To describe the temporal characteristic of a resource

you may use plain text,

title	Transports in Kazakhstan 2000 - 2010
coverage	2000 - 2010

as linked data

or structure your entry using dates,

title	Transports in Kazakhstan 2000 - 2010
temporal
	start	2000	W3CDTF
	end	2010	W3CDTF

as linked data

or period labels.

title	Analysis of rocks collected in Perth
temporal
	start	Cambrian period
	scheme	Geological timescale
	name	Phanerozoic Eon

as linked data

Further information on encoding temporal characteristics you will find in the DCMI Period Encoding Scheme.

To describe the spatial character of a resource, you could use plain text,

title	Analysis of rocks collected in Perth
coverage	Perth, W. A.

as linked data

or express it by georeferencing,

title	Analysis of rocks collected in Perth
spatial
	east	115.85717
	north	-31.95301
	name	Perth, W. A.

as linked data

or reference to a formal encoding.

title	The growth of trees in the suptropical highlands
spatial
	label	Cwb
	source	Köppen-Geiger Climate Classification
	main Climates	warm temperate
	precipitation	winter dry
	temperature	warmest month averaging below 22°C

as linked data

Further information on encoding spatial characteristics you will find in the DCMI Box Encoding Scheme and the DCMI Point Encoding Scheme.
