Aim: Use OGC:GetCapabilities document to produce metadata for services and layers in ISO19119/139

• 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
