Overview

This proposal allows editor to add extent information based on keyword analysis. In the editor a button is added to run the process :

1. For each keywords
2. Search for the keyword in thesaurus
3. If keyword in the thesaurus has an extent
4. Add an extent with a description and a bounding box to the metadata record.

The process could be run in 2 modes :

• Add : Keep existing extent elements and add the new one at the end. Editor could clean the section after processing.
• Replace : Remove all extent having only a bounding box (temporal, vertical and bounding polygon are not removed), and add the new one at the end.

Select your keywords

Suggestion for futur improvements

• Support for CT_CodelistCatalogue

​http://asdd.ga.gov.au/asdd/profileinfo/anzlic-allgens.xml There are about 10 categories (CodelistItem) with hundreds, if not thousands, of GENs (gml:description@gml:id) to choose from. This may help in testing the speed of your interface. The order of the "|" separated bounding coordinates (gml:description) are north|south|east|west.

• Add EX_GeographicDescription
