In this paper, ontology-based Tantra Social Information Management Framework is proposed to manage information about a complex system such as society in a unified manner. The objective of Tantra Framework is to usher in good governance and social change by playing a prominent role in E-Governance. Tantra Framework enables four different viewpoints of social information: (1) collection of entities, (2) hierarchy of macrostates and microstates, (3) multi-modal social network and (4) social system with macrolevel properties and propensities. An entropy construct is crafted as an instrument for validation of Tantra Framework that can work with each of these viewpoints. With its generic nature and power of detailing, Tantra Framework can become a harbinger of next-generation information systems.
