基于OAIS的城市记忆资源分层元数据模型设计

摘要

元数据的设计是城市记忆资源库建设的核心技术环节,城市记忆资源的多媒体集成性、资源组织多维性和处理过程复杂性等特点对元数据的设计提出了较高要求。本文以OAIS参考模型为指导,基于多源异构城市记忆资源,从内容视角、根据资源处理过程复杂的特点从流程视角设计了城市记忆资源分层元数据模型,对城市记忆资源的准确描述、有效控制、高效组织具有一定意义,有助于形成一个多主体参与、跨领域整合、全流程管理的资源平台,为工程实践提供参考。

Abstract

Metadata design is the core technology of city memory database construction. The multimedia integration, multidimensional organization and complex process characteristics of city memory resources put forward higher requirements for metadata design. Introducing OAIS reference model, based on multi-source heterogeneous city memory resources, this paper designs the hierarchical metadata model of city memory resources from the perspective of content and resource processing. It is of great significance to the accurate description, effective control and efficient organization of city memory resources,which can be a reference for engineering practice of constructing a multi-agent participation, interdisciplinary integration and whole-process management resources platform.
