Abstract. Semantic content annotations are not enough to construct
the Semantic Web; these semantic data need to be linked. This is what
the Linked Data fourth rule covers. Apparently, only the author of the
content can do this task, but in this article we explore the possibilities
of semantic technology and we study whether it is possible to create
some types of semantic links more automatically, without intervention
by the author. Furthermore, we study the problem of guaranteeing that
the annotation in fact represents the content to which it refers, bearing
in mind that the annotation should be as immediate as possible. As
a result of these considerations, two new rules are proposed that make
very clear the need to develop tools that automate the common-ontology
based data link, thereby facilitating the update, security and consistency
of the semantic information.

Keywords: Semantic Web, Semantic Views, RDFa, OWL, SPARQL,
semantic annotation, Linked Data.

1 Introduction

In the last two years a critical mass of formally annotated information has been
generated with semantics, based on the Linked Data concept [1]. The Semantic
Web not only consists of publishing formally annotated data on the Web, but also
of linking them with others, so that people and computer systems can explore the
web of data and obtain related information from other initial data. It is in this
context where the concept of “Linked Data” arises. In fact, it is a logical evolution
of the foundational concept of the Web, the hyperlink, towards the formalisation
and automation that the Semantic Web adds. It is the data link that gives
the semantic web its value and also its power as a distributed computational
knowledge system.
There are four rules that define this concept:

1. Using URIs (Uniform Resource Identifiers) as unique names for the resources.
2. Using the protocol HTTP to name and determine the location of the data
identified with these URIs.
