On the Road to Bring Government Legacy Systems Data Schemas to Public Access
Raquel Lima Façanha, Maria Cláudia Cavalcanti · 2014
Government organizations produce and disseminate a large quantity of information every day. Open government data movement have made these data available for reuse and accessibility. However, to merely publish data re- trieved from legacy systems is not enough for reuse and integration. Despite the approaches proposed to publish government data, using technologies like XML, RDF e OWL, these are not suitable for representing real intended meaning of database conceptual schemas belonging to legacy systems. Some approaches pro- pose using top-level ontologies. This paper aims to raise the difficulties to estab- lish the ontological commitment of legacy schemas towards top-level ontologies. It illustrates the difficulties by describing a small case study on the Legal domain.
