ICSM ISO19115-1 Metadata Best Practice Guide

Data Identification ★★★★

When capturing information on a spatial resource, it is important to identify and categorise information as pertaining to the data resource and to distinguish these information from that which applies to the metadata itself or service resources. MD_DataIdentification extends the abstract class MD_Identification to document a spatial data resource.

Definition -

basic information required to uniquely identify and understand a data resource.

ISO Requirements

At least one [1..*] MD_Identification must be present in a metadata record. This must be instantiated as a MD_DataIdentification for metadata about data rsources.

Discussion

Identification information about a resource is of high importance to document as this information strongly impacts on the ability of a user to asses the resource fitness to use. MD_DataIdentification instantiates the abstract class MD_Identification for use with data resources.

ICSM Best Practice Recommendations

Therefore - to clearly understand what resource a metadata record is describing, there should be one and only one [1..1] MD_Identification package in a metadata record. For dataset metadata, this must be expressed as an MD_DataIdentification instance. The Data Indentifaction package contains several sub-packages and sub-elements. To ease the common use of such metadata, it is important that the use of these sub-packages and sub-elements be standardised.

The following provides additional guidance to MD_Identification element recommendations.

In addition to all the attributes of MD_Identification, the additional recommended elements apply -
