Updating multidimensional XML documents
(2008)
Purpose-In a wide spectrum of applications, it is desirable to manipulate semistructured information that may present variations according to different circumstances. Multidimensional XML (MXML) is an extension of XML ...
The branching-time transformation technique for Chain Datalog programs
(2001)
The branching-time transformation technique has proven to be an efficient approach for implementing functional programming languages. In this paper we demonstrate that such a technique can also be defined for logic programming ...
Finding equivalent rewritings in the presence of arithmetic comparisons
(2006)
The problem of rewriting queries using views has received significant attention because of its applications in a wide variety of data-management problems. For select-project-join SQL (a.k.a. conjunctive) queries and views, ...
A semantic mapping of VRA Core 4.0 to the CIDOC conceptual reference model
(2011)
In the recent decades, we have witnessed a tremendous proliferation of metadata schemas, particularly in the cultural heritage domain. As a consequence, there is a growing need to integrate these schemas to solve a number ...
Query Transformation in a CIDOC CRM Based Cultural Metadata Integration Environment
(2010)
The wide use of a number of cultural heritage metadata schemas imposes the development of new interoperability techniques that facilitate unified access to cultural resources. In this paper, we focus on the ontology based ...
Temporal disjunctive logic programming
(2001)
In this paper we introduce the logic programming language Disjunctive Chronolog which combines the programming paradigms of temporal and disjunctive logic programming. Disjunctive Chronolog is capable of expressing dynamic ...
Linearisability on datalog programs
(2003)
Linear Datalog programs are programs whose clauses have at most one intensional atom in their bodies. We explore syntactic classes of Datalog programs (syntactically non-linear) which turn out to express no more than the ...
Multidimensional RDF
(2005)
RDF has been proposed by W3C as a metadata model and language for representing information about resources in WWW. In this paper we introduce Multidimensional RDF (or MRDF), as an extension of RDF, suitable for representing ...
Defining a semantic mapping of VRA Core 4.0 to the CIDOC conceptual reference model
(2012)
In the recent decades, we have witnessed a tremendous proliferation of metadata schemas, particularly in the cultural heritage domain. As a consequence, cultural heritage communities face a growing need to integrate these ...
Modelling the Public Sector Information through CIDOC Conceptual Reference Model
(2010)
Nowadays, due to the growing development of eGovernment information systems, there is an increasing need to handle Public Sector Information (PSI) in a homogeneous way. Ontologies are currently a powerful tool to act as ...
