The migration of legacy web applications (LWA) to Service Oriented Architectures (SOA) has become mainstream in the last years due to the architectural flexibility that SOA provides, which allows to easily adapt the existing applications to new requirements. However, these migrations are usually ad-hoc and manually performed leading to tedious and...

International organizations, as the World Health Organization (WHO), are constantly defining new healthcare protocols and procedures, as well as modifying previously adopted ones. As a result, most health institutions have to adapt continuously their workflows and information systems in order to be aligned with international standards. This problem...

Administrative workflows are very useful in large enterprises and public institutions but, in order to use them adequately in their different areas and departments, they must be adapted to the particular conditions of each one, complying with the general regulations of the process established at the top level. This problem, called Hierarchical Adap...

Increasingly, public administrations and some companies are providing your data in reusable formats. Those that choose to offer the highest quality data reuse usually have a SPARQL access point so that applications that use them can make queries directly. Instead, citizens do not have that option because they generally do not know the SPARQL langua...

Los workflows para procesos administrativos son utilizados en empresas e instituciones públicas pero, para poder utilizarlos adecuadamente en sus distintas áreas y departamentos, deben ser adaptados a las características propias de cada uno de ellos, respetando las normas que regulan el proceso a nivel general. Este problema, llamado Problema de la...

Administrative processes are a type of business process commonly used in public institutions and large companies. The workflow definitions of these processes are frequently reused within the organizations. The reuse of these workflow definitions can be easier if they are divided into three separate but related definitions: on the one hand, the defi...

Administrative processes are a type of business process commonly used in public institutions and large companies. These processes are generally characterized by involving the submission of some type of application form. This form must be considered at different stages by different users who need to handle current information of a dossier in order t...

Administrative processes are a type of business process commonly used in public institutions and large companies. These processes are frequently reused because there are often similar processes within the organizations.
