Title: GeoConnections Secretariat


1
  • NRCan/GeoConnections
  • OGC activities
  • Brian McLeod
  • Canada Centre for Remote Sensing

2
Overview
  • Digital Rights Management
  • uDIG data viewer

3
GeoDRM intro
  • Geospatial Digital Rights management (GeoDRM) is
    about how to manage data ownership and rights
    management.
  • driven by Business models
  • Increasing use of licensed data in government and
    private sector business processes
  • Introduces need to absolutely verify that
    distribution/redistribution complies with the
    legal terms of licensing
  • Web Services transaction environment opens
    opportunities for geospatial data sharing and
    commerce, but also opens a barn door with
    respect to management of Digital Rights

4
GeoDRM the issues
  • Branding
  • License acknowledgement (click-through licensing)
  • Fine-grained access control (access to data
    within a given set of extents in time and space)
  • IP rights protection for sensitive or proprietary
    data
  • Service chaining and cascading
  • Pricing and Ordering

5
GeoDRM technical issues
  • Rights expression language
  • Authentication and authorization
  • Uses mainstream web service architecture
    (SOAP/WSDL)
  • Must be robust
  • Must be transparent to the user
  • Service chaining

6
GeoDRM OGC current activites
  • OGC activity coordinated through the GeoDRM
    working group
  • Very active working group (3 co-chairs!)
  • Abstract rights model
  • Demonstrator (mini IE)
  • Interoperability Experiment
  • Reference model (draft due for Bonn meeting)
  • OWS-3

7
OWS-3 DRM key use cases
  • click thru license, anonymous user
  • click thru license, after authentication
  • Service chaining

8
Results
  • Key results to be demonstrated in OWS-3 demo next
    month

Missing Link for OpenGIS
  • Integrated Client
  • Ability to directly view WMS
  • Ability to directly edit WFS
  • Ability to search catalogues
  • Ability to integrate standard GIS data
  • Hide complexity of network access

15
Missing Link for Open Source
  • Standard GIS Functionality
  • Ability to directly edit GIS data
  • Ability to connect to PostGIS, Mapserver,
    GeoServer
  • Ability to create paper cartography
  • Ability to integrate with proprietary
    infrastructures
