The Location Core Vocabulary provides a minimum set of classes and properties for
describing any place in terms of its name, addrress or geometry. The vocabulary is specifically
designed to aid the publication of data that is interoperable with
EU
INSPIRE Directive. It is closely integrated with the Business and Person Core Vocabularies.

Introduction
The Location Core Vocabulary was developed under the European
Commission's
ISA Programme
. This is the namespace document, generated
from the associated RDF schema. Full documentation is provided in the
Core Vocabularies Specification
specification document itself. This includes background information,
use cases, the conceptual model and full definitions for all terms used.
Namespace
The URI for this vocabulary is
http://www.w3.org/ns/locn#
When abbreviating terms the suggested prefix is
locn
Each class or property in the vocabulary has a URI constructed by appending a term name to the vocabulary URI. For example:
This section provides the formal definition of each class in the vocabulary.
Class
Location
Type of Term
Class
QName
dcterms:Location
URI
http://purl.org/dc/terms/Location
Definition
dcterms:Location class fully represents the Location Core Vocabulary class of Location.
Usage Note
This is the key class for the Location Core Vocabulary and represents any location, irrespective of size or other restriction.
Class
Address
Type of Term
Class
QName
locn:Address
URI
http://www.w3.org/ns/locn#Address
Definition
An "address representation" as defined in the
data specifications
of the EU INSPIRE Directive. The
locn:addressId
property may be used to link this Address to other representations.
Class
Geometry
Type of Term
Class
QName
locn:Geometry
URI
http://www.w3.org/ns/locn#Geometry
Definition
The Geometry Class provides the means to identify a Location as a point, line, polygon, etc. expressed using coordinates in some coordinate reference system.
Usage Note
This class defines the notion of "geometry" at the conceptual level, and it shall be encoded by using different formats. For interoperability reasons, it is recommended using one of the following:
The location property links any resource to the Location Class.
Asserting the location relationship implies only that the domain has some connection to a
Location in time or space. It does not imply that the resource is necessarily at that location
at the time when the assertion is made.
A geographic name is a proper noun applied to a spatial object. Taking the example used in the
INSPIRE document
(page 18), the following are all valid geographic names for the Greek capital:
A?n?a (the Greek endonym written in the Greek script)
Athína (the standard Romanisation of the endonym)
Athens (the English language exonym)
For INSPIRE-conformant data, provide the metadata for the geographic name using a skos:Concept as a datatype.
Property
geographic identifier
Type of Term
Property
QName
rdfs:seeAlso
URI
http://www.w3.org/2000/01/rdf-schema#seeAlso
Definition
rdfs:seeAlso fully represents the Location Core Vocabulary concept of a geographic identifier.
Usage Note
Used in the Location Core vocabulary to provide a URI that identifies the location.
This should be expressed using the rdfs:seeAlso property unless the identifier is already the subject of the description.
Examples include URIs from
GeoNames.org
and
DBpedia
such as http://dbpedia.org/resource/ISO_3166-2:XX where XX is the ISO 3166 two character code for a country.
Property
geometry
Type of Term
Property
QName
locn:geometry
URI
http://www.w3.org/ns/locn#geometry
Range
http://www.w3.org/ns/locn#Geometry
Definition
Associates any
Location
with the locn:Geometry class.
Usage Note
Depending on how a geometry is encoded (see usage note of the
locn:Geometry
class), the range of this property may be either a literal (e.g., WKT - string literal -, GML, KML - XML literal) or a geometry class, as those defined in the OGC's
GeoSPARQL specification
, in the W3C's
Basic Geo (WGS84 lat/long) vocabulary
, and at
schema.org
, or even the
GeoHash
URI references.
The following are examples of equivalent statements using different geometry encodings:

Usage Note
Best practice is to use the ISO 3166-1 code but if this is inappropriate for the context, country names should be provided in a consistent manner to reduce ambiguity. For example, either write 'United Kingdom' or 'UK' consistently throughout the data set and avoid mixing the two.
