The new GeoNetwork opensource comes with substantial upgrades of different components for a more intuitive and responsive user-system interaction. Web2 technologies have been adopted, in particular AJAX techniques, to allow for more interactive and faster services in the web interface and for the integration of the existing web map viewer in the home page. Similar functionalities have been implemented in the administrative part of the system, to provide an easier access to the configuration pages related to site settings, catalogue harvesting, scheduling and maintenance.
The search interface has been completely overhauled to provide highly interactive searching capabilities. Furthermore, the new version of GNos embeds GeoServer as map server. Users can now not only overlay OGC web map services available on the web, but also create their own map services for other users to browse without having to download additional plugins. Maps created with web map services can be now saved as PDF and sent to others.
The metadata catalogue handles the latest ISO19115:2003 geographic metadata format based on the ISO19139:2007 schemas, as well as the older ISO19115 final draft format, FGDC and Dublin Core. The metadata editor is able to handle the majority of these complex standards, providing default, advanced and XML editing online tools.
The new version has a number of different harvesting interfaces allowing users to connect their own server to many other catalogues around the world. This is the result of the implementation of the open source reference for the web catalog services according to OGC specifications. Harvesting in the new version is fully compatible with GeoNetwork 2.0 and higher nodes.
We have added avanced online and offline administration funcionalities to
configure, backup and migrate the application. We have also added a convenient
import and export format "MEF" or Metadata Exchange Format,
that allows the users to
move metadata, previews and even data in a convenient single file. GNos can be
easily expanded with plugins to export/import metadata to/from other software
supporting MEF.
