ISO 191** Suite of Geospatial Metadata Standards

  1. Home

iso suite of standardsISO geospatial metadata standards have been developed as a suite of standards. The base Fundamental standard (ISO 19115-1) is the core of the suite. Fundamentals includes information common to most geospatial data resource types.

 Additional standards have been developed to:

  1. extend the Fundamental standard by adding content that must be used in conjunction with the Fundamental standard
  2. document related information that can be stand alone or associated with a Fundamental metadata record
  3. encode and validate a standardize XML metadata record

The suite approach enables metadata creators to select and apply only those standards relevant to their organization and data types. The suite also enables the one time documentation of information, e.g. Data Acquisition and Processing, Feature Catalogs, Data Quality Methods and Measures, etc., that may be applied to multiple geospatial resources and their associated metadata records.

Content (UML) and Encoding (XSD) Standards

ISO standards generally reference both a content standard and an XML encoding standard. Content standards use UML conceptual diagrams to illustrate the relations among metadata elements and a data dictionary to define the element conditionality, data type, and domains. Encoding standards specify the XML format and rules used to create and validate the output metadata records. The table below provides detailed information about the ISO geospatial standards publications and associations between content and encoding standards.

Note: ISO is currently shifting practices to develop encoding standards, when feasible, as an ‘Annex’ of the associated content standard.
