Requirements
The Metadata Explorer uses the following libraries:
This component extends Ext.panel and uses widgets that interacts each other to provide the needed functionalities. Inside the panel there are
combobox for the catalog selection
search field : implements an "any text search" functionality.
advanced search panel : hidden at first, provides search filters for:
- temporal extent
- specific Bounding box
- specific Dublin Core field
grid : lists, in pages(using CSW pagination), the records of the catalog. Each record can be expanded showing an abstract and three buttons:
View Metadata: if the record is releated with a GeoNetwork(GN) Resource, will be opened a new window in the web browser at the GN resource relative page. Else the application will open a panel showing all Dublin Core metadata avaible (only the CSW standard DC metadata)
View Map: if the record has a WMS resouce releated, using this control the user can add a layer to the map. (at the moment the application only opens a window that shows layer data)
Show BBox: if there is a BBox associated to the record, execute a zoomToExtent to the relative area of the map.
The component must have cross browser compatibility between the following browsers
- Firefox (last realese)
- Chrome (last realese)
- Internet Explorer 7, 8, 9
