Status draft
Assigned to release Release number, to be determined
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

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
