Propuesta de un estandar para solucionar los problemas de interoperabilidad semántica entre sistemas de tratamiento de datos de seguridad social

Abstract

Population movements, especially migratory movements, are a phenomenon of great social and economic impact. Guaranteeing the exercise of Social Security rights for people moving around the world requires the implementation of a series of agreements between the competent institutions in different countries. The fact that these agreements have a real effectiveness requires the exchange of data between completely heterogeneous information systems. In this context, interoperability techniques play a key role for these systems to be able to understand each other. This thesis will address the interoperability problems that arise in this area, especially those related to semantic aspects, proposing a solution based on the standardization of a set of metadata that accompany each of the data exchanged in order to avoid any ambiguity or equivocal interpretation. As a starting point for the proposed standard, Dublin Core has been chosen, as it is specially adjusted to the needs detected and its wide implementation in all areas, including the public administration. As has been done in other domains, this set of elements has been adapted, modifying several of them and adding three extensions. An important aspect is that the metadata set is based on a series of controlled vocabularies that allow defining and delimiting their possible values. These vocabularies have a different degree of development. Its revision and extension is proposed as a future line of research that gives continuity to what is proposed in this thesis
