In an interesting entry on the Semantic Web, a fellow blogger writes:
However, the Semantic Web, which is still in a development phase where researchers are trying to define the best and most usable design models, would require the participation of thousands of knowledgeable people over time to produce those domain-specific ontologies necessary for its functioning.
I’ve italicized part of this quote, as it requires comment.
This is a common perception – i.e., that people need to be directly involved in the manual creation of formal ontologies.
Frankly, this simply isn’t the case.
Vehicles such as GRDDL are already available and designed to automate the creation of informal ontologies from the bottom up. More specifically, GRDDL facilitates the extraction of RDF from XML.
I’ve spelled all of this out via a scientific example elsewhere.
Fortunately, you don’t need to take my word on this – you can go to the source: a Tim Berners-Lee keynote at a recent BioTech event.

The Global Grid Forum (GGF) and the Enterprise Grid Alliance (EGA) announced yesterday (June 26, 2006) their merger to form the Open Grid Forum. Many will regard this as a very positive development. More importantly, this is a very necessary development. Why? At this juncture, Grid Computing has minimal ability to tolerate fragmentation in standards. In fact, Grid Computing sorely needs to deliver outcomes that matter – and this will only come from focus … in standards and elsewhere.
Working for Grid software vendor Platform Computing, Inc. for about seven years, it took ‘a little distance’ for me to appreciate ‘all of this’ – i.e., and to be perfectly blunt, Grid Computing isn’t quite as big a deal as many would like it to be.
Even though it won’t make this unpleasant pill any easier to swallow, allow me to elaborate via a few anecdotal data points:
- Despite convergence efforts such as the Open Grid Services Architecture (OGSA), Web Services continues to significantly eclipse Grid Computing. And for those who’ve delved into the reeds a little deeper, the ‘evolution’ of the Open Grid Services Infrastructure (OGSI) into the Web Services Resource Framework (WSRF) serves only to amplify this perception. Extrapolating further suggests the possibility for ‘collateral damage’ – e.g., as the gap between the promise and reality of the Semantic Web decreases, and Web Services increasingly plays a facilitative role, the Semantic Grid runs the risk of being not much more than a footnote.
- Despite their ‘validation’ of Grid Computing, through their endorsement of the Open Source Globus Toolkit, IBM markets more around virtualization these days … and virtualization (think vmWare, Xen, etc.), along with Web Services, is also proving to be a big deal.
- With the notable exception of Platform Computing and perhaps a small handfull of others, Grid Computing startups are struggling to land customers and, frankly, survive – this is also in stark contrast to those companies that make Web Services or virtualization their business. Moreover, a ‘supply chain’ continues to gel around Web Services (e.g., just Google “Web Services”) and virtualization (e.g., PlateSpin) – a supply chain that features start ups having compelling value propositions.
- The highest-profile demonstrations of Grid Computing run the risk of trivializing Grid Computing. It may seem harsh to paint illustrations such as the World Community Grid as technologically trivial, but let’s face it, this is not the most sophisticated demonstration of Grid Computing. Equally damaging are those clustered applications (e.g., Oracle 10g) that market themselves as ‘Grid-enabled applications’.
- Applications can be effectively Grid-enabled by drawing on non-GGF or non-EGA standards. Scali Manage 5 provides a compelling illustration by drawing on Web Based Enterprise Management (WBEM) and Eclipse; whereas WBEM is an umbrella for a number of standards all under the auspicies of the Distributed Management Task Force (DMTF), Eclipse is an implementation framework and platform available from a consortium.
I remain a Grid Computing enthusiast, but as a realistic enthusiast I believe that “Grid Computing sorely needs to deliver outcomes that matter”.
That being the case, yesterday’s creation of the Open Grid Forum is necessary, but is it sufficient?
