Actually no oversight at
all...I did not intend to bring SemWeb standards into my explanation. My
explanation was focused on the interoperability that SOA-RM can bring between
SOA-based systems, which is something that comes right out of the SOA-RM
spec.
As to how the DRM benefited from the
guidance in SOA-RM: Speaking only for myself, I was a major contributer to both
initiatives, as both a member of the OASIS SOA-RM TC and the primary contractor
supporting DHS (the lead agency) for the creation of DRM 2.0. You may note some
cross-pollination between the two reference models (e.g. the definition of a
reference model, what it is used for, etc.) which was partly due to ideas that
flowed from SOA-RM to DRM 2.0, which were both being created at the same
time.
Hope that helps,
Joe

2.0
Joe,
With
respects. What I see in your note is that OASIS SOA-RM
can
serve as a conceptual guidance for something called "by various people" Web
2.0. However, not all of the SemWeb standards are anywhere close to the
SOA RM. You note does not seem to acknowledge this fact. Perhaps
this is an oversight?
In the
SOA RM here are a set of very specific concepts developed in a simple fashion
(38 pages ?) and some of these are concepts that seem to me, and others, to just
be ignored in other standards. You mention the federal data reference
model.
Many
months ago, I questioned the definition of community that is in this data
reference model, and the fact that the documents describing this reference model
are not easy to grab hold of conceptually. I still have that
opinion.
The
OASIS SOA RM, on the other hand can be read and understood by any well meaning
freshman college student.
The
DRM on the other hand is not easily understood, and part of this is that there
are authoritarian statement about how things are; when in fact there are good
reasons to suggest that the "thing" is not as described. I will take the
term "relationship" to start with, section 3.4. The DRM Abstract
Model is useful but it is focused on computer data. The sometimes vast
differences between computer data and the real world is not addressed or even
hinted at. The SOA-RM consistently explicitly deals with this
difference. So in this precise sense, I would claim that (in this specific
sense) the DRM has not guidance from the OASIS SOA RM.
It is
as if the SOA RM does not exist for the DRM Abstract Model. The Topic Maps
1.0 standard was all about this difference, and the RDF folks beat up on TM
until TM is now almost gone. The issue of correspondence between real
world and data is marginally addressed in the SOA RM because (it is stated) that
the SOA RM is not about "only" the computer data world.
If the
US Federal Data Reference Model is mute on this issue, which I suggest that it
is, then there is no benefit obtained by the DRM from the SOA RM. I
may be mistaken and would love to see the specifics where you , or anyone else,
sees a correspondence between the DRM and the SOA RM. How does, or how
did, or how might the DRM benefit from the guidance in the SOA
RM?
When
one goes to understand what Web 2.0 !! is !! (I think that the phrase "Web
2.0" is just a phase being used with out precisely defined meaning) one gets a
particular (possible) architecture etc for doing something...
What
is this something, in your eyes?
Not
two hundred pages of words in a URL, but in simple terms. A few sentences
or a paragraph.
If you
would be so kind...
I believe the OASIS SOA-RM can provide a foundation for Web 2.0's
advancement because of Web 2.0's focus on collaboration. Such collaboration is
facilitated by interoperability among multiple SOA implementations (meaning
among the services that these implementations provide), and this
interoperability can be facilitated by an enhanced ability to relate and
compare multiple SOA implementations - and such an enhanced ability can be
provided by the SOA Reference Model.

Is there
something that one can directly compare W* or Web 2.0 or what ever (is W*
sameAs Web 2.0) to the OASIS SOA RM?
Joe, in my
humble opinion, the links below have more information than one needs
(information about the author(s) and about his/their
opinions).
To the SOA
CoP...
OASIS SOA
RM is in my opinion complete adequate and sufficient for social
transformations that I am hoping to help.
As has been
mentioned, the "phenomenon" of case based reasoning is vital
to causing the types of complicated cascades that are needed in a new type of computing and communication
. Computers need these cases
enumerated. Web-ontology is
doing this now days and doing it well, in a few
cases. Human
communication needs choice points (BCM standard) and measurements to
test when the cases are not adequate in a particular situation.
What most
miss is that human reasoning is constantly in touch with reality, what I and
others (Aldo de Moor) call the pragmatic
axis.
The OASIS SOA RM does not miss this, and yet most
other standards do miss this - particularly (the judgment can be made) W3C
standards. (Show me one that does, and I will be very happy to review
it.) The reason why this is a RM and not an architecture is to correct
architectures that have no or little reference capabilities to natural
processes. (Again, this means process models and really alignment to
real temporal events.) This is a call for a principled discussion if
someone feels slighted by a slight critic of W3C.
The issue is clarity of the standards, and fidelity
to the natural processes that the standards should be helping us model and
assist ourselves and others with "web services".
Yes?
This is
where an alignment with the OASIS SOA-RM is necessary, because this RM is
correct (in the context I am speaking) and because of the break through
(conceptually) within the leadership (some of it) of the Federal CIO Council,
in this context. We feel that
more than any other thing, other than an
awareness of n-ary ontology and Ontology referential bases, this alignment to
the OASIS RM has the greatest merit.
Stakeholders will understand this
alignment, but we need to demonstrate
that we have mastered this RM
and understand how to do web
service architectures within the scope of the RM.
In my mind, not having seen all standards, for
me.....The SOA-RM, the FERA (Federated Enterprise Reference Architecture)
and the following other standards
complete a * cover over the high level standards the federal government should
adopt.
SOA-IM
(Information Model)
SOA-CS
(Collaborative Services)
BCM
(Business Centric Methodology) adopted at OASIS in April 2006.
ebXML
(electronic business XML) strongly supported by SUN and reasonably
good.
* by cover,
I mean that all of the issues are taken care of at one level (in this
case the high level cover is a conceptual cover).

FYI -
I wasn't aware of consternation between SOA and Web

SOA
Versus Web 2.0?
As I indicated in my previous posting, a cultural
chasm separates these two
technology communities, despite the fact that
they both rely heavily on the
same foundational standard - XML. The
evangelists for SOA tend to dismiss
Web 2.0 technologies as light-weight
"toys" not suitable for the "real" work
of enterprises. The
champions of Web 2.0 technologies, on the other hand,
make fun of the
"bloated" standards and architectural drawings generated by
enterprise
architects, skeptically asking whether SOAs will ever do
real
work.
Both Web 2.0 and SOA technologies re-conceive software
as services. Perhaps
even more importantly, they view services as
platforms. Rather than viewing
services as standalone offers
designed to be consumed exactly as written,
both sets of technologies
start with the vision that the role of any service
is ultimately to
become the building block for even more services that will
be built on
top of the original service.
Amazon provides an early, and very
limited, example of this opportunity. By
developing an affiliate
program and offering a book buying service that can
be embedded into
other web sites, Amazon has been able to significantly
expand its reach
and create a much more robust platform for driving
e-commerce
activity.
The growing appeal of Web 2.0 technologies in part stems
from this hijacking
of SOAs. Line executives within the enterprise
are experiencing mounting
frustration over the escalating hype around
SOAs, the growing spending over
SOA design initiatives and the relatively
limited business impact achieved
by SOA deployments. In contrast,
Web 2.0 initiatives are leading to a
proliferation of mashups (one form
of composition), as described by Dion
Hinchcliffe in "The Web 2.0 Mashup
Ecosystem Ramps Up" and "Some Predictions
for the Coming 'Mashosphere'
"
Does this mean SOAs are DOA? Not at all. SOAs still
provide a valuable
foundation to support the sustained relationships
required for distributed
creation. But these SOAs need to be
deployed in a much more incremental and
pragmatic way. Perhaps a
little competition from Web 2.0 technologies will
help to break the
logjam and force both IT departments and IT consultants to
adapt their
culture and operations to growing business pressure for
accelerated
impact and learning.
As JSB and I discuss in much more detail in The
Only Sustainable Edge, the
convergence of SOAs, virtualization
architectures and Web 2.0 social
software will drive the next wave of
value creation within and across
enterprises. The convergence will
not unfold smoothly, as much of the
current debate confirms, but it will
take place - there is too much at stake
and each of these technology
arenas offers something distinctive in
supporting next generation
business
platforms.
