One table stores all: Enabling painless free-and-easy data publishing and sharing

Abstract

In this paper, we present a free-and-easy data publishing and sharing system based on folksonomy. The system ac- cepts data objects described with user-created metadata, called data units. The system supports exible structure on the data units, and places no restrictions on the vocabulary used. We devise a generic table model for storing and rep- resenting the data units of various structures. We propose a framework for managing the data units and providing brows- ing, searching and querying services over them. We present our current approaches and discuss relevant research issues.
