ISO Metadata Standards

• ISO TC 211: committee for geographic information standards

• Standards are reviewed every 5 years

• 77 standards have been published

• 26 standards in development

• 32 standards withdrawn

Types of metadata standards

• Content standards

- What to write

• Implementation specifications

- How the content is stored

• Validation

- Is it good?

Metadata Styles

• FGDC CSDGM Metadata

• ISO 19139 Metadata Implementation Specification

• North American Profile of ISO 19115:2003 (NAP)

• INSPIRE Metadata Directive

FGDC CSDGM standard Styles

• Content Standard for Digital Geospatial Metadata (CSDGM)

- Implementation is included in this standard

Supporting cast of ISO metadata standards

• ISO 19110:2016 Methodology for feature cataloguing

- Implementation is included in this standard

ISO metadata XML schemas

• Historically

- Not all standards have published schemas

- Published to different locations

- Not designed to work together

• More recently

- Incorporated into same distribution page as other standards

- TC 211 schemas no longer publicly available from this location

• Currently incorporated into Github repository

Exporting ISO format metadata

• ISO 19115/ISO 19139

• Includes data quality content

• References external ISO 19110 documents describing features and their attributes

• Collect content for 19110, but can’t export and manage multiple documents together in
