requests, their authorization, management and
response. Business processes will use business objects
such as logs, semantic resources, and a series of data to
complete the requests. The Validation Team will be
responsible for managing these business processes.
The business processes will be executed through a
series of services reflected in the Institutional Business
Services. These services will expose their functionality
through interfaces (Institutional Service Interface).
The business processes will be developed in each
institution with a number of elements at the
application level. The institutions have a set of
applications that will offer a series of functions and
they will be accessible through services with their
corresponding interfaces. These applications will use
data for processing.
5 CONCLUSIONS
The implementation of international social security
agreements requires an intensive use of ICT at
different levels: international, national and
institutional. Furthermore, it is imperative that the
information exchange between social security
institutions is carried out in a secure and coordinated
manner. While each institution has their own
information processing systems and business
procedures, the interoperability mechanisms play a
key role to interconnect them in order the
international agreements.
This paper addresses the involved issues,
particularly the interoperability ones, and proposes a
general enterprise architecture that allows the
development of interoperable systems at the interna-
tional, national and institutional levels. Through these
architecture levels, it is a matter of guiding the
designers of the computer systems in charge of
carrying out the international agreements. The
architecture levels provide a series of basic elements
that will be part of these systems but without going
into specific details related to the internal processes
to be applied. It has been presented in a general way
to make it easier to implement or adapt to the different
technologies used by social security institutions.
The main contributions of the paper are the
specification of these three architectures in
coordinated way tacking into account characteristics
of the social security area. In addition, the use of
ArchiMate has allowed to formalize the enterprise
architecture and together with EIRA, elements of
interoperability between public administrations can
be represented.
Future work would consist of more detailed
specifications, formalization and prototyping.
