With the emerging use of electronic calendars services on the Internet the users are constantly increasing the number of calendar platforms they use and the need to have them synchronized in one place is increasing. In this paper we discuss the evolution of the electronic services for calendars, and give overview of the APIs they use, along with protocols and interfaces to these services. We in...

This thesis investigates real-life calendars, calendar and time expressions, and time and date formats. The thesis aims at the development of computer-based tools for modeling and processing such calendric data, primarily in the “World Wide Web”, in particular regarding today’s internationalization efforts and the vision of the “Semantic Web”. Applications are not only appointment scheduling pr...

From a chronological point of view the substitution for the mean calendaric system of one based on the true movements of the sun and moon, was anything but an improvement, as it destabilized the foundations of the time reckoning. Indeed, the system may have had the charm of adapting daily life as nearly as the astronomical knowledge permitted to the movement of the heavenly bodies, but on the o...

Abstract Traditional calendars document seasonal cycles and the communities’ relationships to their biophysical environment are often used by communities, particularly subsistence farmers, synchronize livelihood activities with timing of ecological processes. Because these processes is not always consistent from year year, use traditional can help communities cope climate variability, when phen...

Digital calendars have been heavily influenced by the design of the physical calendar and have invariably adopted their grid representation of days in the month. We argue that the alternative of a continuous list representation of successive days would offer several advantages such as faster calendar search, a more natural linear view of time, a scrollable and zoomable interface and better scal...

Temporal information in the real world is often presented in an incomplete fashion. In this paper we propose a constraint-based calendar system suitable for inferring implicit calendric information. Our approach views calendars as constraint satisfaction problems, and time points are represented as instantiations of temporal units. We also present a semantic model for the system to justify the ...

We propose a security framework for Decentralized Shared Calendar. The proposed securityframework provides confidentiality to replicated shared calendar events and secures the commu-nication between users. It is designed in such a way that DeSCal preserves all of its characteristicfeatures like fault-tolerance, crash recovery, availability and dynamic access control. It has been...
