Rule-Based Application Development using Webdamlog

TL;DR

The paper introduces WebdamLog, a rule-based system for managing distributed web data, demonstrated through the Wepic application for decentralized photo sharing at a conference.

Contribution

It presents WebdamLog as a novel rule-based framework for decentralized data management on the Web, with a practical application example.

Findings

WebdamLog effectively manages heterogeneous devices and services.

The Wepic application demonstrates flexible, decentralized data sharing.

Rules can be easily modified to adapt the application.

Abstract

We present the WebdamLog system for managing distributed data on the Web in a peer-to-peer manner. We demonstrate the main features of the system through an application called Wepic for sharing pictures between attendees of the sigmod conference. Using Wepic, the attendees will be able to share, download, rate and annotate pictures in a highly decentralized manner. We show how WebdamLog handles heterogeneity of the devices and services used to share data in such a Web setting. We exhibit the simple rules that define the Wepic application and show how to easily modify the Wepic application.
