Applicability of Multi-model Databases for Accessible Indoor Navigation

Abstract

In this paper an accessible indoor navigation data model suitable for multi-model NoSQL databases is proposed, based on iLOC and iACC ontologies. We consider our previous observations about practicality and performance of labeled property graph data models used for accessible indoor wayfinding and suggest multiple ways of improvement by using a multi-model approach. A very important aim of the new data model is to provide a structure to be able to run fully customizable wayfinding queries with respect to accessibility needs of disabled users.
