摘要： A computer based method for the preservation of a digital information in a data set includes receiving a data set to be preserved, the data set including a plurality of preservation objects; creating a fixity table, the fixity table including one or more data types corresponding to preservation data types contained in the preservation objects, each data type being assigned an importance rank and one or more fixity function; for each preservation object, creating a Merkle tree corresponding to the preservation object and based on the fixity table.

摘要： Methods for generating a characterizing summary and generating a collection of relevant preservation objects in a preservation system are provided. A characterizing summary is generated by collecting first information about a preservation object; collecting second information about other preservation objects or other metadata; generating a characterizing summary according to the first information and the second information; and adding the characterizing summary to the preservation object. A collection of relevant preservation objects is generated by accessing one or more preservation objects by way of one or more metadata included in a target preservation object constructed for content data; determining whether each of the accessed preservation objects is relevant to the target preservation object; adding each relevant preservation object to a list of relevant preservation objects; and generating the collection of relevant preservation objects according to the list of relevant preservation objects.
摘要翻译：提供了在保存系统中生成表征概要和生成相关保存对象的集合的方法。通过收集关于保存对象的第一信息来生成表征概要; 收集关于其他保存对象或其他元数据的第二信息; 根据第一信息和第二信息生成表征概要; 并将特征摘要添加到保存对象。通过以包含在针对内容数据构建的目标保存对象中的一个或多个元数据访问一个或多个保存对象来生成相关保存对象的集合; 确定每个被访问的保存对象是否与目标保存对象相关; 将每个相关保存对象添加到相关保存对象的列表中; 并根据相关保存对象的列表生成相关保存对象的收集。
