Re: [ontolog-forum] RIF vs Ontology

[Adrian Walker <adriandwalker@xxxxxxxxx>]

Hi Pavithra,

Good questions.

Not only is there overlap between OWL and Rules, but there's some question about what the extra conceptual complexity of OWL buys us.

Please see for example:

http://lists.w3.org/Archives/Public/public-owl-dev/2010OctDec/0018.html

and later posts in the same thread.

                            Cheers,  -- Adrian

Dr, Sowa,

In my opinion,  RIF should capture all the business rules and policies by industry.   And Ontology should address the entity, structure and relationships..     They are side by side on Semantic Web Layered cake ..

 RuleML website says the following..
The RuleML Initiative is an international non-profit organization covering all aspects of Web rules and their interoperation, with a Structure and Technical Groups that center on RuleML specification, tool, and application development

Do they mean just "web rules"? and the structure  developed based on rule that leads to logic and relationships? And not Business Rules?   By the way what are the web rules?

In traditional analysis and design, genrally developed in assocition with certain operation, busienss function, process  .. etc showing a relationship about who it  applies ..  For example, a taxpayer has to pay taxes by April 15 ..  ( based on certain criteria..).

Then there are business requirements vs just rules.   ( how the rules should be applied to.. )..

Seems like there is some overlapping areas between Ontology and RIF...  I like to know what other people's opinion on this..

That is an example of the kind of errors that plague any large
collection of data.  Fortunately, no pilots or drivers are likely
to use the NY Times to find their way to Berlin.

But when enough people use any database, somebody is sure to
encounter some erroneous data.  Many drivers have been led astray.
And some have died -- typically by blindly obeying the GPS lady
and turning in front of a train at an RR crossing.
