Modeling Open Accessibility Data of Public Transport.

Nowadays linked open data (LOD) is a great challenge in the area of information technologies. In fact, some public administrations and organizations are working to open their data to citizens. LOD describes a method of publishing structured data to become more useful. Heterogeneous distributed data sources which have been published as LOD, could be integrated. The information of public transport networks is of public interest. A classic example is the route planning systems which combine data from different public transit networks. Besides, a relevant aspect of the public transit networks is the accessibility of this media which make possible the mobility of special needs people. Due to the large amount of these data, LOD provides the mechanism to publish them and to support new mobility services to the citizens. The aim of this work is present the process to define public transit data and their accessibility information as LOD from diverse data sources taking into account some of the main reference data models for public transport: IFOPT.
