GeoNetwork is a catalog application to manage spatially referenced resources. It provides powerful metadata editing and search functions as well as an interactive web map viewer. GeoNetwork can harvest resources from WHOS through the OAI-PMH protocol, using ISO 19139 metadata schema.
You can find more documentation and download GeoNetwork from the GeoNetwork homepage.
Quick instructions to install GeoNetwork and make it harvest from WHOS follow as well.
Download, compile & run GeoNetwork with:
$ git clone --recursive git://github.com/geonetwork/core-geonetwork.git geonetwork $ cd geonetwork $ git checkout master $ git submodule update --init $ mvn clean install $ cd web $ mvn jetty-run
At this point you should be able to login using admin:admin at web page: http://localhost:8080/geonetwork
Click on Admin console → Harvesting → Harvest from → OAI-PMH
Input the name for the new source, and in the URL input field paste one of the available OAI-PMH endpoints, depending on the view of interest. Example given:
Arctic view OAI-PMH URL
La Plata river view OAI-PMH URL
Optionally select the desired set from the list, in order to download from a specific source only.
Select the metadata schema to be used for harvested records, choosing among one of the available. E.g.:
- ISO19139 (2006 version)
- ISO19139 (2006 version, with GMI package)
- ISO19139 (2007 version)
- Dublin core
The metadata schemata in bold were the supported ones using GeoNetwork 3.10.x.
After a successful harvesting, clicking on the Search button a search portal similar to the following should appear, listing the resources of interest matching user search criteria:
