Kingsley Idehen's Blog Data Space

Dare Obasanjo's post about the issue of Open Data (or Open Data Access), indicates that the "Open Data" issue is gradually beginning to resonate across a broader audience.

From my perspective on things I prefer to align my articulation of the changes that are occurring across our industry (courtesy of the Internet Inflection) to the MVC pattern.

Re. the Web Versions (or Dimensions of Interaction):

Web 1.0 - (V)iewer (Interactive Web experienced via Browser)

Web 2.0 - (C)ontroller Web (via Web Services API)

Web 3.0 - (M)odel (via the RDF Data Model as the basis for an Open and Standards based Concrete Conceptual Data Model)

The same applies to evolution of Openness:

Early work by Sun and other early UNIX Vendors - (V)iewer (Interaction with the same OS across different hardware platforms)

Open Source Movement - (C)ontroller (Open Access to Application Source Code )

Open Data - (M)odel (*where we are now* Freeing the Date from the Applications and Services while moving the application development focus to a Concrete Conceptual Data Model focus. The Data Web is a classic example.)

In the (C)ontroller realm where the focal point is Application Logic, data access issues aren't obvious (*I recall my battles with Richard Stallman re. the appropriate Open Source License variant for iODBC during the embryonic years of database and data access technology on Linux*). Data is an enigma in this realm, unfortunately. This implies that "Data Lock-in" occurs deliberately, but in most cases, inadvertently when we make Application Logic the focal point of everything. Another example is Web 2.0 in which the norm (unfortunately) is to suck in your data, and then refuse to give you complete ownership over how it is used (including the fact that you may want to share it elsewhere).
