IS 16439 : 2025 Metadata Standard for Geospatial Information
1 SCOPE
This standard specifies metadata to provide a framework for documenting the spatial data and declare its content for the users. It facilitates finding spatial data as per their needs and deciding whether the spatial data meets the specific application requirement. This standard allows describing the dataset in order to understand the uses and limitations of the data while distributing amongst the organizations. This standard provides a key to the information on the schema, which describes the information about the data and distribution of dataset where the fields are clearly mentioned as mandatory or optional. This standard defines the schema required for describing geographic information and related services by means of metadata.
The principles defined in this standard may be extended to other types of resources, for example maps, charts, textual documents and non-geographic data.
2 CONFORMANCE
2.1 Conformance Requirements
Any metadata claiming conformance with this part of IS standard shall pass the requirements described in the abstract test suite specified in Annex B. Metadata shall be provided as specified in 6.2.1.
This standard defines metadata used to describe data. Datasets defined in accordance with this standard may coexist with other datasets that conform to earlier versions of this National Standard. Domain specific or regional profiles of this part of the standard are responsible for establishing the details of backward compatibility in their domains. Conformance clauses for services that operate using metadata defined in accordance with this part or profiles developed based on this part of the standard need to be defined in those profiles or service specifications in order to permit backward compatibility in their domain.
2.2 Abstract Test Suite
For the purposes of conformance testing using the abstract test suite in Annex B, metadata classes and elements shall be considered to be mandatory or optional as specified in the applicable profile.
