MashMap: Application Framework for Map-Based Visualization of Lifelog with Location

This paper presents an application framework, called MashMap framework, which facilitates development of location-based lifelog services. The proposed framework imports various types of location log data, and stores them in a database with the Life Log Common Data Model (LLCDM). A developer first creates a data source consisting of a filter and a display format. The filter extracts necessary data from the database, while the display format defines how the data is shown on the map. The developer then defines a MashMap by choosing a single or multiple data sources. The MashMap is an object, which aggregates several data sources on a single map, shown in the designated display format. The object is finally visualized on a Google Map by MashMap renderer. We conduct a case study developing a travel log review service and a conference history map using MashMap framework.
