Leveraging Metadata Standards in ArcGIS for
Interoperability
• Metadata standards: why, what, and when
- Why metadata and metadata standards
- Status of metadata standards and profiles
• Creating standards-compliant metadata in ArcGIS
- ArcGIS notes for all standards and profiles
- FGDC CSDGM metadata
- ISO 19139 metadata
- North American Profile (NAP)
- INSPIRE Metadata Directive
- ANZLIC and other ISO profiles
- Customizing the metadata editor
Metadata standards: why,
what, and when
Usefulness and utility of released data rating system
Data is released (PDF of scanned paper)
Data is structured, in machine-readable
format (Excel file)
Data is in an open file format (CSV file)
Data uses consistent format, discoverability
methods and metadata associations
Data uses URLs to identify things
Data is linked to other linked data
Why is geospatial metadata important?
• Geospatial data is an imperfect abstraction of the real
world
- A model, a “point of view”
- Assumptions, limitations, approximations, simplifications
• Ensures we understand the geographic information
- The producer is not usually the user
- Supports good information management
• Geospatial resources are valuable
- Reuse
• Oh yeah—it helps us find the right information for the
right purpose
Why use metadata standards?
• Provide resource producers an idea of the metadata they
should collect
• Provide consistent terminology for global search
• Provide an common understanding of data – around the
Globe and across information communities
Regional and national standards from the mid 1990s

• Content Standard for Digital Geospatial Metadata (FGDC
1992)
• Directory Information Describing Digital Geo-referenced
Data Sets, CAN/CGSB 171.3-95
• Australia & New Zealand: Core metadata elements for
land and geographic directories in Australia and New
Zealand
• CEN TC287: Geographic Information - Data description –
Metadata (1996)
• All except FGDC have moved to ISO 19100 standards
- FGDC now starting to transition to ISO standards
ISO Metadata standards
• ISO 19110:2005/Amd 1:2011 Methodology for feature
cataloguing

Changes coming to ISO 19115 and ISO 19139
• Today
- ISO 19115 defines content
- ISO 19139 defines encoding rules and the encoding (XML
schema)
- Encoding rules define how to create XML Schema from UML
• Future
- ISO 19115-1 defines improved content
- ISO 19115-3 defines encoding (XML schema)
- Revise ISO 19139 to define encoding rules only
