While working with the Interoperability Frameworks for e-government services at country level, one theoretical issue that I’m faced with is, the debate on methodology for attaining interoperability in e-government context. For some, it is the National Enterprise Architecture (NEA) and for others it is the Government Interoperability Framework (GIF).
However, while going through both NEAs and GIFs of various countries, an emerging trend is witnessed, that the distinctions are getting blurred gradually – at least the way these are documented. Though, I need to get it validated – independently.
All the GIFs contain ‘standards’, so does the EAs, the difference though, is the way in which these standards are categorized and clustered.
Take the case of GIFs first. Australia (2005), Brazil (2006), Denmark (2005), Malaysia (2006), New Zealand (2006) and the UK (2005) (- let’s call them the first lot-) categorizes the standards according to ‘technical layers’ but Germany (2006) and the EU (2004) ( – the second lot) uses ‘services or life events’ to categorize the standards .
The ‘layered’ model – used by the first lot – clustered the standards in typical technical categories (or layers) such as interconnection, data integration, information access and presentation, metadata and security. Clearly the focus here is only on the ‘technical’ dimension of interoperability. In comparison – the second lot – grouped the standards in such a way, that the focus spreads beyond just the ‘technical’ dimension of interoperability to the ‘organization/process’ and the ‘data/semantic’ dimensions of interoperability as well. The standards – in the second lot – are categorized according to the services or life events such as income taxes, job search, social security contribution, personal documents, car registration, permits, certificates, enrollment, announcement of relocation and health-related services etc.
Interestingly however, it is also observed that many countries – many from the first lot – have reviewed and few others are still reviewing their original GIFs and are planning to address the unattended dimensions (‘organization’ and ‘data’) of interoperability in their future versions of GIFs. The possible reason for taking the route of addressing the technical interoperability first, by the majority of the countries, could have been the ease in standardizing the technical matters(?).
Take the case of the latest version of New Zealand’s e-GIF (2008). It clusters the standards in layers such as network, data integration, business services, access and presentation, web services, security and best practices. The ‘web services’ is comparatively (w.r.t 2006) a latest addition and attempts to address the missing links of ‘organization’ and ‘data’ dimensions of interoperability.
The point is, in cases of older GIFs, if the standards were not categorized by the life events, then categorization of standards was limited to technical layers only, neglecting the two (organization and data) of only three (organization, data and technical) aspects of interoperability. However with addition of new categories such as ‘web-services’ (still under ‘technical’ dimension though) this missing link is being attempted to be bridged.
There is another trend though. Many countries instead of revising their existing GIFs, are working through their respective National Enterprise Architecture (NEA) to address the ‘organization’ and ‘data’ dimensions of interoperability. This confluence is now reflected in the latest versions of the GIFs and the NEAs. The distinctions are getting blurred.
Consider the case of the Commonwealth of Massachusetts’s – Enterprise Information Technology Architecture (2008). This can be treated at par with any National Enterprise Architecture (NEA) in a limited context. The Enterprise Technical Reference Model (ETRM) which provides an architectural framework to identify the standards, specifications and technologies that support the commonwealth’s computing environment, uses access and delivery, information, application, integration, management and security to categorize the standards – a very similar classification system as seen in the latest version of New Zealand’s e-GIF.
Do you see a converging trend here?
