But they tend to be too influenced by other technologiesthat have nothing to do with RDF, and abuse ofimplementing proprietary APIs instead of using pureSPARQL approaches.

Class-based programming languages

Class-based programming languages are those which use acomputational model where objects are grouped on sets withequal structure and behavior as instances of the same class.

Thus there is a heavy link between an object and its class oninstantiation, and it is not possible to create and use anobject without previously define its static structure andbehavior on a class.

Conclusions andfuture work

Prototype-based programming languages

Prototype-based programming languages aim to be morefaithful to the object computational model, where it is onlynecessary to have objects, no additional abstractions such asclasses are required.

The common behavior is defined by what is known as “traitobjects”. The shared structure is represented as prototypeobjects, which inherit their behavior from the trait objects.

Therefore the state is always defined as objects. Thecreation of objects (actually instance objects) is done usingcloning those prototype objects.

RDF

RDF (Resource Description Framework) is an assertionallanguage that provides an extensible and flexible data model.

Based on the concept of triple:

(subject, predicate, object)

RDF is the core technology of the Semantic Web.

RDF (II)

Formally a RDF triple is defined as a tuple (s, p, o) that(s, p, o)ε(U ∪B)×U × (U ∪ L∪B), where U is the universeof all possible named resources, identified by an URI, B isthe finite set on blank nodes, and L is the set with all RDFliterals.

Therefore a set on triples is structurally interpreted as agraph G = (V ,E ), where V is the set of vertices thatV ⊂ (U ∪ B ∪ L), and E is the set of named arcs thatE ⊂ V × U × V .

For each triple (s, p, o) of the RDF data model, there is adirected arc, p, between nodes s y o.
