摘要
敦煌石窟数字资产数据量庞大且内容丰富,涵盖几何、图像、音视频和描述等多种信息,传统的数据表达方式难以有效管理这些多样化的数据。本文基于敦煌石窟数字资产管理平台的构建需求,结合OAIS模型和敦煌石窟数字资产的产生与流转过程,深入分析了平台架构、系统流程、数据类型、服务对象和数据组织结构等内容,设计了敦煌石窟数字资产数据组织模型。同时,基于UUID编码思想设计了与存储目录相关联的数字资产统一标识,采用RDBMS与NOSQL相结合的方式,设计了分布式可扩展且支持高效检索与分析的数据库系统,通过对主流RDBMS分析,本平台选择MySQL数据库,利用建模工具构建了敦煌石窟数字资产管理平台主数据库模型,阐述了设计流程与注意事项,分析了数据管理中关键流程与表关系,展示了数据组织模型应用实践与压力测试结果。本研究不仅实现了数据的全流程管理与利用,而且为敦煌石窟数字资产的科学管理、永久保存与合理利用提供了安全可靠的数据库服务,同时也可能为其他文化遗产单位的数字资产管理数据库建设提供了有价值的参考。
The digital assets of the Dunhuang Caves are an enormous cache of data that is extremely rich in contents,and which includes images,audio and video,textual descriptions,and more.The size and diversity of the information,however,make it difficult to effectively manage this data by relying on traditional methods.Therefore,the goal of this paper is to construct a platform for the management of the digital assets collected at the Dunhuang Caves,to which purpose an in-depth analysis of the platform architecture,system flow,data types,service objects and data organization structure was conducted.On the basis of these results,a digital asset data organization model has been created by combining an OAIS model with the generation and flow process of the data.According to the idea of UUID encoding,this model includes a unified identification of digital information that is connected to the storage directory.The resulting database system,which was generated using RDBMS and NOSQL,is distributed,scalable,and supports efficient retrieval and analysis.The main database model of the new Dunhuang Cave Digital Asset Management Platform was constructed by using the RDBMS database modeling tool in order to achieve a more elaborate design,analyze the key processes of the use of data,determine the table relationships in data management,and be able to display the data organization model application and stress test results.This study not only realizes every aspect of data management and utilization,it also provides a secure and reliable database service for the scientific management,preservation and rational utilization of the digital assets of the Dunhuang caves.In addition,the proposed model is a valuable reference for the construction of similar digital asset management databases in other cultural heritage institutions.
