Geospatial Digital Rights Management (GeoDRM) Graham Vowles (Graham.Vowles@ordnancesurvey.co.uk) OGC Technical Representative, Ordnance Survey, and Co-chair of OGC GeoDRM Working Group Workshop on Grid Middleware and Geospatial Standards for Earth System Science Data 6-8 September 2005 e-Science Institute, 15, South College Street, Edinburgh
Digital Rights Management (DRM) consists of a number of technical elements that should be balanced with initiatives in other areas to increase the protection DRM provides. DRM domains Technical SocialLegal Rights specification Encryption Authentication Packaging Accessibility Expectations Mores Education Legislation Compliance Investigation Enforcement Business Value proposition New business models Source: Robert Bolick, McGraw-Hill, 2001
On-demand service network Knowledge network Information network Technical network Business network GeoDRM is about rights enabling a network of geospatial services
GeoDRM Working Group Part of Open Geospatial Consortium (OGC) – where geospatial standards are defined GeoDRM Working Group – comprises content providers and technology providers Charter is not to invent new digital rights technologies but to reuse and extend for geospatial data and services Formed in June 2004 – Graham Vowles, Roland Wagner, Joe Cardinale Co-chairs Last meeting: June 13–16, St John’s, Newfoundland, Canada.
Ways of managing and protecting intellectual property Weak DRM Strong DRM no protection copyright statement click-through licence managed access watermarking encryption Today we rely on our legal framework and licence agreements to protect our intellectual property Our business is shifting so we need alternative ways to manage and protect our intellectual property
One to One: business to business One to Many: business to consumer Many to many: peer to peer Evolution of rights-managed business models Business Consumer Business ConsumerBusiness Consumer
Digital media DRM vs Geospatial DRM Digital media DRM Trade the rights to a discrete object. For example, the rights to listen to an audio file Business model is B2C and traditional supply chain. Limited number of parties involved in the transaction Similar in concept to buying property freehold No rights to resell or create derived works Static products Geospatial DRM Trade the rights to access a geospatial dataset for a given geographical space for a defined period of time Business model is B2B and networked. A number of intermediaries may be required, each playing a specific role within the GeoDRM network Similar in concept to renting a property or buying leasehold Possibly includes the rights to publishing derived works Dynamic services
Digital media DRM vs Geospatial DRM (part 2) Digital media DRM OwnerUser Licence create content consume content Extents of licence are ‘one-dimensional’ rights. Display, print, play and so on Geospatial DRM OwnerUser Licence create content consume content Extents of licence are ‘multi-dimensional’ rights and space and time and so on Intermediary
GeoDRM Licence extents Licencee Simplified view of the extents of a GeoDRM Licence: three dimensions of rights, space and time Time Rights Space
Imagine yourself transported into the GeoDRM universe No longer the normal three dimensions – but the intellectual property dimensions of rights, space and time… You are now an intellectual property magnate dealing in the rights to access information. A bit like rental agreements in the real world. You could directly license individual users to access blocks of intellectual property, or it may be easier to delegate licensing responsibility to intermediaries Licence management is the process of ensuring a user’s information request falls inside that user’s licence extents
