Re: [ontolog-forum] Webs and Fabrics

There are three parts to my response


1. Here is some notes on Linked Data..

Linked Data as "a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF."

1. Use URIs to identify things.
2. Use HTTP URIs so that these things can be referred to and looked up ("dereferenced") by people and user agents.
3. Provide useful information about the thing when its URI is dereferenced, using standard formats such as RDF/XML.
4. Include links to other, related URIs in the exposed data to improve discovery of other related information on the Web.

http://www.ted.com/talks/tim_berners_lee_on_the_next_web.html

( bla bla, compete with data base technology with simplicity..)

2.   What does this do more than a sql query does on a database?  Semantically nothing  other than the facts SQL query accesses a database objects and this accesses web objects or stuff..

SQL query is a data manipulation language  ---? DML...

3. My question is:  Is that all you want to do with Semantic Web?   If so, may be we are done ..   Time B L told us so.
 Bur if you want to actually do something more like processing and computing data in a complex manner,  does this allow us to do that?   Nothing I have read so far tell me that it is capable of doing so.

Let me tell a story.   Oracle supported Data Manipulation language, data definition langugae and Data control language.  But all the processing code had to be written by the front end application,  middle wear etc.   Later on they supported some event driven processing using the concept of triggers and stored procedures..  This is a procedural / event driven concept implemented using data base technology.  ( a little convoluted, but competed with procedural language processing..)

There are procedural languages that actually allow complex computation.  Java is one of them..     Either one can explore the concept of procedural languages that are already in use for web development,  or use linked data concept and add on baggage later ( like oracle did..)..

I think it is simplicity with sagging, heavy baggage attached.. that will come later on..

Pavithra

John,

I agree with the general "skunk works" theme 100%, but Java isn't a
great example today IMHO. Lots of bloat in Java land (codebase and
community process).

Linked Data (hypermedia based structured data) and the Linked Open Data
community are "skunk works" examples that emerged from the larger and
somewhat maligned Semantic Web project :-)
