Using microdata for international e-Government data exchange: The case of social security domain

Abstract

Semantic interoperability issues of international e-Government data exchanges have not been solved up until now. In the case of social security institutions, the data exchange operations have some particularities that make that the non-ambiguous definition of core concepts used in the institutions has a key impact on the success and quality of system interconnections. In this article, we present the result of a research to implement a new metadata specification based in Dublin Core elements for international social security exchanges, named Exchange Social Security Information Metadata (ESSIM). This proposal is based in a semantic approach using Linked Data for Interoperability, with technologies, such as RDF(S), SPARQL, Microdata and JSON-LD, in order to ensure interoperability between social security institutions from different countries. This will help to strengthen the protection of the social security rights of mobile workers by automating the application of international agreements on social security and to improve cross border communication between social security institutions of different countries. For the near future, the goal is to include this specification as part of information and communication technology Guidelines under development by International Social Security Association with the participation of authors of this article. This will facilitate a future adoption of the specification as an international standard.

Blockchain-Enabled Social Security Services Using Smart Contracts

“…Taking the field of social security as an example, F. Delgado et al studied the international e-government data exchange method [14], using linked data to achieve interoperability to ensure interoperability between social security institutions from different countries, but the system It is centralized and lacks an introduction to how to ensure the security of authority authentication. Zheng Yan et al proposed a new decentralized system using blockchain technology to establish a trust evaluation under social networks [15], but there is a lack of research on how to solve data sharing in heterogeneous networks.…”

“…1 compares existing social service solutions with ours. [14] is based on non-blockchain technology and studies the social security field, e-government data exchange methods, using data links to achieve interoperability to ensure interoperability between social security institutions from different regions, but the system is centralized and does not guarantee trustworthiness and traceability between different institutions of social security. The solution proposed in [13] is implemented based on consortium blockchain, which explains how to improve the efficiency of data sharing among social security institutions, focusing on data security communication, one of the limitations of this work is that it does not show Testing and coding details of smart contracts.…”
