Monetising SDIs... eLicensing and ePayment for
Spatial Services
  • Rüdiger Gartmann, on behalf of Andreas
    Wytziskcon terra GmbH, Münster, Germany

2
SDI Value Chain
3
Basic Assumptions
  • Spatial information is valuable
  • even if its for free!
  • Spatial information can be used for commercial
    products
  • its raw material for spatial products,
    applications, etc.
  • Spatial Data Infrastructures (SDIs) are the
    distribution network
  • moving the raw and semi-finished products from
    the producer to the user
  • If value is created along the value chain, there
    is a need for metering and accounting!
  • And spatial information is heterogeneous!
  • Its not sufficient to summarise what is taken
    from and given to the network

4
Power Networks
  • Homogenious good
  • Producers measure their output
  • Users measure their consumption
  • Only balance is determined
  • Actual origin of product does not matter
  • gt Unlike SDIs!

Value Chains
  • SDIs are classical value chains
  • Along the value chain, raw materials are assemled
    to semi-finished and finally to end products
  • Each step adds value, so each step may need
    individual accounting

6
Interoperability
  • Find the right content!
  • Product catalogs
  • Search tools
  • Technical integration
  • Standards
  • Services
  • Legal agreements
  • Negotiate contracts?
  • Sign papers?

7
Applying Business Aspects to SDIs
  • Status quo of SDIs ensures technical
    interoperability
  • Applying business aspects
  • must not break technical interoperability
  • must ensure immediate workflows
  • must support existing technology
  • must solve all business requirements (terms and
    conditions, prices, rights and duties, ...)
  • cf. INSPIRE Data Service Sharing Implementing
    Rules
  • Convey legal terms and conditions
  • Transparency of charges
  • Licence creation without delay

8
eLicensing of Geo Services
  • Protection aspect
  • Services are protected against unlicenced access
  • If a valid licence is provided, access is granted
  • If the licence includes restrictions (e. g.
    spatial, content, ), these have to be enforced
  • Conclusion aspect
  • Licence offer
  • Licence agreement
  • Management aspect
  • Maintenance of existing licences
  • Accounting

9
Data Sharing in SDIs
  • Why is spatial special?

10
Product Aspects
  • Books
  • Price
  • Geo products
  • Geographic extent
  • Layers
  • SRS
  • Data format
  • Price formula, with regard to the parameters
  • Download or service
  • ...

11
Challenges for Licensing Solutions
  • Be generic
  • Support different business models
  • Click-through vs. configurable licenses
  • Free of charge vs. flat rate vs. pay-per-use
  • Pre-paid vs. post-paid
  • General access vs. user-specific access vs.
    license configuration-based access
  • Provide an easy-to-use workflow to
  • clearly convey license terms
  • allow easy license conclusion
  • give immediate access
  • limit access to license terms

Elements of Licence Models
  • Licence description (What is it all about?)
  • Terms and conditions (What is allowed? What is
    not?)
  • Configuration options (Customise your licence)
  • Access rights (How can you access the service?)
  • Price models (What do you have to pay?)
