  1. 2.12.2 Temporal Reference System

Description of the temporal reference system(s) used in the data set.


Metadata element name

Temporal Reference System


COMMISSION REGULATION (EU) No 1089/2010 , article 13, point 2


Description of the temporal reference system(s) used in the data set.

ISO 19115 number and name<!-- I think that the more suitable class to document the temporal Reference System is RS_ReferenceSystem in the Reference System Information package (its definition by ISO 19115 is "description of the spatial and temporal reference systems used in the dataset" - see <a class="external" href="http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/gmd/referenceSystem.xsd">http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/gmd/referenceSystem.xsd</a>). That class could be conformant also to the Standard 19108 (Geographic information - Temporal schema), which, at Annex C (normative) defines the metadata elements for describing temporal reference systems. Unfortunately the above mentioned class is defined by ISO 19115 as abstract and without any relations with other classes. So, I haven't found the way to use it. Any idea? -->


ISO/TS 19139 path


INSPIRE obligation / condition

Conditional. Only required if a non-default temporal reference system (i.e. Gregorian Calendar or the Coordinated Universal Time) is used.

INSPIRE multiplicity


Data type (and ISO 19115 no.)








This element is mandatory only if the spatial data set

contains temporal information that does not refer to the default temporal reference system which is assumed as either Gregorian Calendar or Coordinated Universal Time.




TG Requirement 42 Temporal Reference System property is not mandated by ISO 19115 but is mandated for conformance to the INSPIRE Regulation 1089/2010/EC only if the Temporal Reference System is other than Gregorian Calendar or the Coordinated Universal Time. (See Article 13, clause 5).
