Of course. But a group of bright folks with a good deal of
experience in both knowledge representation and XML created RDF (which is a
dialect of XML).
Why would you want to re-do that work?

Subject: Re: [ontolog-forum] Can Syntax become Semantic ?
Hi,
As Ed was also pointing out that they need to agree upon the ontology they are
using.
Few points that I can comprehend from your reply :
RDF creates a standard way for the process to happen.
What if people across
the whole world start using a standard way of doing this which can be enhancing
from time to time ?
I do understand that the tags etc.. in RDF enables us to represent the info in
more natural terms. But what is it semantic w.r.t computers/systems ?
For example, to describe an item the thing that differs from a normal XML to
RDF is that I add "rdf:about" to that item and give a resource
for the same. That resource itself is another URL or URI in terms of W3C. So,
even the systems just know that you are describing about some entity (the above
resource) if at all there exists a rule in the program which says that "rdf:about"
means description etc.
For that, I can have an attribute "about" in XML itself and
have the above resource as its value and let machines process it.
So, I can plug-in my program above also except that my rule changes from "rdf:about"
to just "about" in XML.
I read it somewhere that "semantics" w.r.t systems is that they
should be able to process our information.
And also as Rich was also saying that SW is just one way of doing this
May be, I should ask first that "what does semantics mean w.r.t
computers" and what is the goal of semantic applications with a neat
example. Along with that I would also like to read about any references for the
same.

A trading system application acts as a
third party broker between the buyer and seller. Both buyer and seller register
with the trading system and the trading system matches goods offered with buyer
requests for goods. The match could involve an auction (as eBay does) or a direct
trade or purchase.
The semantic web eliminates the trading
system. Assume that a seller creates some information on the web that is
annotated with RDF. The buyer uses a search service (perhaps implemented with
SPARQL) to search the web. This search service is general in nature (like
Google) and is provided by many sites on the web, or it may be a personal
implementation provided by the buyer or seller. The RDF provides a standard way
for sellers to describe their offerings without interfering with the sellers
ability to create a personal and pleasing web experience. It also standardizes
the way buyers can frame a query.
Does this help?

Hello
all,
I have a doubt in the semantic web applications. I mean, how semantic is the
application that we build which can contribute to semantic web.
For example, if I want to build an application which does buying/selling of
some items (let's say cars).
Now broadly there are two types one being who wanted to buy a car and the other
who whanted sell a car.
So, if I have a RDF file which get's generated whenever a person enters info.
like name, address, email, the type of car he/she wants to sell, price etc ..
with a RDF ID.
Similaryly I will have the info. for person who would like to buy that type of
car.
Now, what should my application do ? whenever one wants to buy a car .. my
system should search for those types of car put up for sale by some others.
For it to work, one needs to have a DB to search upon which essentially is a
search engine db. All I gained in terms of semantics is representing in RDF
which is one form of XML.
For, a computer to process the info. we need to explicity provide the
heuristics for it to undergo some actions on seeing some tags.
So, how Syntax can become Semantic ?
Sorry, if I don't make any sense. But I would really like to know about
semantic web and it's applications.

Phani Chaitanya.
