Abstract
Most existing location-based services rely on ubiquitous connectivity to deliver location-based contents to the users. However, connectivity is not available any- where at anytime even in urban centres. Underground, indoors, remote areas, and foreign countries are examples situations where users commonly do not have guaranteed connectivity but could profit from location-based contents. In this work, we propose an open platform for publishing, distributing and maintaining location-based contents that can be accessed offline by the user on a mobile device. Ad- ditionally, we describe the prototype we implemented for proof of concept consisting of an smartphone application and a web application backoffice, using 2D-barcodes as location identifiers. Our prototype provides offline access, as well as publishing, installing and updating location- based content.
