Re: [teiid-dev] [DBpedia-discussion] Protocol
by Sebastian Samaruga
Its true that OData is a really good protocol, in the sense that it is more
an 'application' layer over HTTP and I've been inspired by that. This way
this proposal is also a meta-protocol over HTTP and paths are built along
the lines of URI paths like:
/someSubject[path]/somePredicate[path]/someObject[path]
in the realm of some domain. Posted paths and metadata (referrer) are
submitted through request body and headers. Let me work a while for real
examples.
I think I've missed some important part for the 'application' layer (as
HTML is for the 'document' oriented web) that is the 'representation' part
of the resource. This paragraph added to the document (incomplete, confuse,
questionable due this hypermedia approach) tries to address the issue:
"Representations (requesting client metamodel resources) are built upon
aggregating and aligning protocol dialog 'path' resources into data (Fact,
Event), information (Kind, Rule) and knowledge / behavior (Class, Flow) in
the requesting node, maybe by multiple ‘posts’ / traversals of activated
contexts. Those are the same models which get 'activated' in the requested
side by means of async messages IO."
This is all but a incomplete draft of thoughts. Please be patient if bother
in reading.

Protocol
by Sebastian Samaruga
Hi, newbie question again: what if a 'protocol' can be regarded as an issue
for the 'data web' as there is one for the traditional 'document web'. The
question is: does the design issues (ex.: RESTful application design
patterns) of a document resource centric web holds (or at least part of
them) for the concept of a 'data web' only because it relies in the same
protocol / patterns (HTTP).
See attached file (or Protocol section in the link) for a first (confuse /
abstract / questionable) set of thoughts in the subject:

Re: [teiid-dev] About your post on "Semenatic Web"issues
by Sebastian Samaruga
Hi,
I've been discussing this issues: the transition from a 'document oriented'
web into a 'data and services oriented web' for a while in the semantic-web
related w3c mailing lists. In short it seems we had have to deal with
building 'applications' over *documents* for a long time and it seems it
does not need to be the the same within a data oriented web (at least for
me).
However, applications does not build by themselves. XML and others promised
interoperability since a long time before RDF and, although I belive RDF /
SW could, there will be no interoperability (as that of RESTFul services)
until there is no agreement in 'semiotic' semantics of representations,
resources and protocols.
The document I'm attaching here is an extended version of yesterday's
abstract but it only states a few concepts regarding integration (alignment
and merge of datasources. I'm not a seasoned SW nor integration developer).

Draft thoughts
by Sebastian Samaruga
Hi,
This is a message I usually post into semantic web related mailing lists.
As for my point of view SW could provide a 'glue' for what JBoss Teiid or
Apache Metamodel provides I'm posting copy here (sorry for cross posting):
I've tried to state in a document again what I'd like to solve. This time
I'm trying not to focus on how I'd like to implement things but more in
what I'd like to have implemented. At the end (of the document also) I
state the most important thing I'd like to do: to be able to build better
web applications (semantic or whatever).
