SYSTEM OF MANAGING RELATION AND HISTORY ON COMBINATION OBJECT OF SPACE OF INTEREST AND CONTENT

摘要

PURPOSE: A system for managing relation and a history of a connection object between space-of-interest (SOI) and content is provided to manage the SOI and the content by assigning a unique identification relation ID to the relation of the SOI and the content, thereby extending the relation of the SOI and the content through extension and connection of relation IDs. CONSTITUTION: An SOI/content selection unit (420) newly generates an SOI object or content with a predetermined reference or selects a specific SOI object or specific content among existing SOI objects or existing content. An SOI-content relation management unit (440) generates and manages content of SOI information. When at least one of the SOI object, the content, SOI-content relation information, and SOI-content attribute information is changed, an SOI-content history management unit manages a change history corresponding to time. An SOI-content history restoring unit searches and displays the change history of an external request.
