Resources | Indicate if the required resources are available to complete the proposal |
Overview ¶
Use the OGC:GetCapabilities document to produce metadata for services and layers in ISO19119/139 format
- add metadata of services based on ISO19119 in GeoNetwork.
- add import XML document functionnality using XSLT stylesheet
- add harwest WxS GetCapabilities
Proposal Type ¶
- Type: New functionality
- App: GeoNetwork
- Module: Harvester, Metadata Import

Voting History ¶
- Vote not yet proposed.
Uses cases ¶
- UC1 : Create metadata using copy/paste the GetCapabilities document of a WxS service (i.e. Create a full ISO19119 MD based on a GetCapabilities request)
- UC2 : Harvest metadata from a WxS service (i.e. Create a full ISO19119 MD based on a GetCapabilities request)
- UC3 : Update Bbox section of a dataset metadata based on WMS GetCapabilities info (i.e. Update part of MD based on a Request)
Import GetCapabilities document ¶
Harvest GetCapabilities document ¶
Parameters ¶
- Input parameter : URL of the service for which to create metadata
- Ouput parameter :
- ISO19119 metadata xml file to be load into GeoNetwork
- ISO19139 metadata for each layers of the services
- (optional) thumbnails
