Scope

This Technical Specification defines Geographic Metadata for imagery and gridded data (gmi) encoding. This is an XML Schema implementation derived from ISO 19115-2, Geographic information – Metadata – Part 2: Extensions for imagery and gridded data.

Implementation benefits

This standard specifies the implementation of ISO 19115-2:2009, Geographic information – Metadata – Part 2: Extensions for imagery and gridded data, in XML. It uses and extends ISO 19139:2007, Geographic information – Metadata – XML schema implementation, which uses parts of GML, which is defined in ISO 19136:2007, Geographic information – Geography Markup Language (GML).

As the revision of ISO 19115:2003, Geographic information – Metadata, namely ISO 19115-1:2014, Geographic information – Metadata – Part 1: Fundamentals, has now been published, ISO 19115-2:2009 and ISO 19139-2:2012 will both need to be revised to benefit from ISO 19115-1:2014. As with the revision of ISO 19115:2003, the current versions of ISO 19115-2:2009 and ISO 19139-2:2012 will then be deprecated when their revisions are published, but will still be available because of the masses of legacy metadata conforming to ISO 19115-2:2009 and ISO 19139:2012.

The benefit of implementing ISO 19139-2:2012 will be to access all the metadata encoded using it and to promote one’s products and services by providing one’s metadata to clearinghouses using ISO 19139-2:2012 for disseminating metadata.

However, this does not mean that the only way to implement ISO 19115-2:2009 is through XML, as defined in ISO 19139-2:2012. ISO 19115-2:2009 can be implemented in databases and GISs, and encoded using other markup languages such as JSON or GeoJSON, interchange formats such as ISO/IEC 8211 or ASN.1, or even as comma-separated values.

Implementation guidelines

ISO 19139-2:2012 is an extension to ISO 19139:2007 and implements the metadata defined in ISO 19115-2:2009 through a collection of XML schema that conform to ISO 19118:2011, Geographic information – Encoding. Unsurprisingly, the standard requires a sound knowledge of XML to understand it. The reader also needs to understand ISO 19118.

Clause 5.2 specifies the UML model stereotypes used in this standard. Clause 6 describes the XML namespaces used in this standard, namely gmi, gco, gmd, gml, gmx, gss, gsr and gts. With the exception of gmi (Geographic Metadata for imagery and gridded data), these are the same namespaces used in ISO 19139:2007. Clause 6 also provides the XML Schema Definitions (XSDs) for gmi. Clause 7 briefly describes the XML document requirements.

Annex B briefly describes the XML resources related to geographic metadata for imagery and gridded data and Annex C provides some implementation examples. The actual XML defined in ISO 19139-2:2012 is provided in an online repository, rather than just printed out in the standard. This is not the ISO repository used for ISO 19139:2007, but rather an ISO/TC 211 repository that is also used for ISO 19139:2007 and other standards from ISO/TC 211. See http://www.isotc211.org/2005/.
