All,
Edited, as I just realized some critical typo+errors that affect
context.
Hopefully, you understand what Nathan is articulating (ditto
Giovanni). If not, simply step back and as yourself a basic
question: What is Linked Data About?
Is it about markup? Is it about Data Access? Is it about a never
ending cycle of subjective commentary and cognitive dissonance
that serves to alienate and fragment a community that desperately
needs clarity and cohesion.
Experience and history reveal the following to me:
1. Standards based data access is about to be inflected in a major way
2. The EAV (Entity-Attribute-Value) graph model is the new focal
point of Data Access (covering CRUD operations).
Microsoft, Google, and Apple grok the reality above in a myriad of
ways via somewhat proprietary offerings (this community should
really learn to look closer via objective context lenses). Note,
"proprietary" is going to mean less and less since their
initiatives are HTTP based i.e., it's all about hypermedia
resources bearing EAV model data representations -- with varying
degrees of fidelity.
**
Players and EAV approaches:
1. Microsoft -- OData (EAV with Atom+Feed extension based data
representation)
2. Google -- GData (EAV with Atom+Feed based data representation)
3. RDF based Linked Data -- (RDF variant of EAV plus a plethora of
data representation formats that are pegged to RDF moniker)
4. Apple -- Core Data (the oldest of the lot from a very
proprietary company, this is basically an EAV store that serves
all Mac OS X apps, built using SQLite; until recently you couldn't
extend its backend storage engine aspect) .
**
Reality re. Business of Linked Data:
"Data as a Service" (DaaS) is the first step i.e., entity oriented
structured data substrate based on the EAV model. In a nutshell,
when you have structured data place, data meshing replaces data
mashing. Monikers aside, entrepreneurs, CTOs, and CIOs already
grok this reality in their own realm specific ways.
Microsoft in particular, already groks data access (they developed
their chops eons ago via ODBC). In recent times, they've groked
EAV model as mechanism for concrete Conceptual Model Level data
access, and they are going unleash an avalanche of polished EAV
based applications courtesy of their vast developer network. Of
course, Google and Apple will follow suit, naturally.
The LOD Community and broader Semantic Web Problem (IMHO):
History is a very good and kind teacher, make it an integral part
of what you do and the path forward becomes less error prone; a
message that hasn't penetrated deep enough within this community,
in my personal experience.
**
Today, I see a community rife with cognitive dissonance and
desires to define a non existent "absolute truth" with regards to
what constitutes an "Application" or "Killer Application".
Ironically, has there EVER been a point in history where the
phrase: Killer Application, wasn't retrospective? Are we going to
miraculously change this, now?
**
Has there ever been a segment in the market place (post emergence
of Client-Server partitioning) where if you didn't make both the
Client and the Server, the conclusion was: we have nothing?
We can continue postulating about what constitutes an application,
but be rest assured, Microsoft, Google, Apple (in that order), are
priming up for precise execution with regards to opportunities in
the emerging EAV based Linked Data realm. They have:
1. Polished Clients
2. Vast User Networks
3. Vast Integrator Networks
4. Vast Developer Networks
5. Bottom-less cash troves
6. Very smart people.
In my experience, combining the above has never resulted in
failure, even if the deliverable contains little bits of impurity.
Invest a little more time in understanding the history of our
industry instead of trying to reinvent it wholesale. As Colin
Powell articulated re. the IRAQ war: If You Break The Pot, You Own It!
Folks, we are just part of an innovation continuum, nothing is new
under the sun bar, context !!
+1
Just to add maybe that CRUD is just one part of the equation, after
that can come aggregation, curation, self healing etc.
Now I'm trying to work out whether what you've presented is good news
or bad.

Looking at the WWW Roadmap, are we all headed for the Sea of
Interoperability or to be sucked in to a Growing Desert Wasteland?

All,
Interesting and poignant listening:

Dallas is to Linked Data what the Apple store is to iPhone apps. Dallas
is a Data Mart, it has infrastructure for Data as a Service in place, of
course it only handles OData, but the simple question for this community
is this: where are the RDF based Linked Data Marts?
