Metadata record
A syntactically correct representation of the descriptive information (metadata) for an information resource.

N

Namespace
A logical grouping of metadata terms. Namespaces allow unique identification of metadata terms to allow those terms to be unambiguously used across applications.

P

Period
DCMI Period Encoding Scheme is a Syntax Encoding Scheme for indicating a single time interval.
Point
DCMI Point Encoding Scheme, a Syntax Encoding Scheme for identifying a point in space using its geographic coordinates.
Property
A specific aspect, characteristic, attribute or relation used to describe a resource (previously called ‘elements’). Dublin Core and AGLS
metadata terms are properties.
Property/Value Pair
The combination of a property and a value, used to describe a characteristic of a resource.

Q

Resource
