RDFS
Semantic Web does not provide reference to object properties
Semantic web knowledge representation is build on triples, which represent subject - predicate - object. Semantic web Standards are using those triples as atomic building blocks for their own specification and any ontology.
With triples knowledge can be specified like in the sentence: "Paul is a Person". "Paul" is the subject, "is a" is the predicate, "Person" is the object.
Subject and object are considered as entities while predicates are considered as object properties are connecting those entities. From this perspective representation of every knowledge is quiet similar to the usage of early days' entity-relationship-diagrams. Also some shortcomings seem to be adopted.
Sentences like: "Paul takes Pauls Car to reach Pauls Office" cannot be described easily. It requires an intermediate, unnatural entity like "Pauls Vehicle Choice" and many sentences: "Pauls Vehicle Choice chosen by Paul", "Pauls Vehicle Choice is Pauls Car", "Pauls Vehicle Choice reaches Pauls Office". Instead of one sentences there are three sentences for describing the equivalent problem.
Isn't there an alternative approach possible?
Using RDF(S) without XML.
RDF can be written in some ways: A RDF triple could be represented through a RDF graph, through FOL expressions like P(X,Y), or - most common used for web development - through XML.
There are some good RDF/XML parsers for the most common web development languages like Perl or Python.
But is there another way of writing RDF, which is supported by a parser for programming/script languages?
