基于OAIS的音视频数据库分层元数据模型
|
摘要
元数据是音频、视频数据库建设中的核心要素,《录音录像类电子档案元数据方案》(DA/T63-2017)虽然根据档案实体、业务实体、机构人员实体和授权实体将元数据进行了分类,但是这种分类法难以很好地指导对音视频文件整个生命周期的管理。本文以OAIS参考模型为基础,从对音视频文件的处理流程视角和各流程对元数据的内容需求视角构建了音视频数据库的分层元数据模型,并结合DA/T63-2017形成了各层元数据方案,有利于对音视频文件的标准化管理、长期保存和有效利用。
Metadata is a core element in the construction of audio and video database. Although the Metadata Standard for Digital Audio and Audio-visual Records(DA/T 63-2017) provides classified metadata from the perspectives of archival entities, business entities, institutional personnel entities and authorized entities, this classification method can hardly guide the management of audio-visual records throughout the life cycle. Based on OAIS reference model, this paper constructs a hierarchical metadata model of audio-visual database from the perspectives of the processing flow of audio-visual records and of the content requirements of metadata in each process. It forms metadata programs in each hierarchy in combination with DA/T 63-2017. This model is conducive to the standardized management, long-term preservation and effective utilization of audio-visual records.
