ISO geospatial metadata standards

Standards

  • Dublin core usually used for opendata portal, referencing publication, report, …

  • ISO 19115/119/139 used for spatial resources (eg. datasets, services, maps)

  • ISO 19110 used for feature attribute table

The editor form provides uploading of data, graphics, documents, pdf files and any other content type. It features include:

  • full standard support

  • multilingual metadata editing

  • validation system

  • suggestion system to improve metadata quality

  • geopublication of layers – publish GeoData layers in OGC services (e.g., GeoServer)

Based on user profiles (group membership and permissions), a dashboard provides easy access to their information and tasks.

Simple summary of standard numbers

You will find information about multiple versions of ISO 19115.

Note

The numbering is unusual since the portion following 19115 is NOT in chronological order.

  • ISO 19115 the original version defining metadata content

  • ISO 19115-2 an extension to 19115 that provided more details for gridded data (remote sensing, model output)

  • ISO 19115-1 This is the newest version defining metadata content

  • ISO 19115-3 This is the newest version of how the content of 19115-1 is to represented in xml

Details

The ISO standards define the content of the metadata (names of metadata elements, what they mean) in a standard. Since it defines the content, there are many possible storage formats. The only ISO-defined representation is in an XML format. That representation is defined in a different standard from the content because there could be a future standard using a another representation.

Notice that ISO changed to using the same base number (19115) for both the content and representation, but with different subnumbers (-1 vs -3)

GeoData currently supports 19115, 19115-2, 19115-3. At this time, 19115-2 is stored internally as 19115-1 to provide full support for metadata elements in -2 that were not in the original.
