305.1 Learning PREMIS Knowledge Base: a tool for humans and machines

Inspired by the “Knowledge Base” definition of the Open Archival Information System: “A set of information, incorporated by a per- son or system, that allows that person or system to understand received information”, we developed a mapping model for a) cap- turing the knowledge base of the digital preservation metadata, represented by the PREMIS Data Dictionary, and b) generating a SKOS vocabulary, that represents the PREMIS Knowledge Base. The article proposes, the PREMIS Knowledge Base as a knowledge tool, targeted to the digital preservation community, that can be used for learning, using, and updating preservation metadata. The tool bridges the knowledge expressed by the PREMIS OWL ontology with its knowledge context, stored in a “computable form”, and obtained by a semi-automatic transformation mapping from the PREMIS Data Dictionary. PREMIS Knowledge Base, as a documen- tation tool, provides designated community with web resources for human consultation, and as a computable knowledge tool, pro- vides RDF resources exhibited for software agent consumption. The PREMIS Knowledge Base candidates itself to be integrated into the PREMIS OWL ontology, via annotation property, allowing ontology and related datasets to be enriched and documentend by their originationg knowledge context, and thus to be properly interpreted.

受Open Archival Information System中“知识库”定义的启发：“一组由个人或系统吸收的信息，使得该个人或系统能够理解接收到的信息”，我们开发了一种映射模型，用于a) 捕获数字保存元数据的知识库，该知识库以PREMIS数据字典的形式呈现，以及b) 生成SKOS词汇表，以表征PREMIS知识库。文章提出将PREMIS知识库作为一种知识工具，针对数字保存领域，旨在用于学习、使用和更新保存元数据。该工具架起了由PREMIS OWL本体表达的知识与其知识背景之间的桥梁，知识背景以“可计算形式”存储，并通过从PREMIS数据字典到知识背景的半自动转换映射获得。作为文档工具，PREMIS知识库为指定社区提供了供人类咨询的网页资源，同时作为可计算知识工具，为软件智能体提供了展出的RDF资源。PREMIS知识库自诩能够通过注释属性与PREMIS OWL本体集成，从而使得本体及其相关数据集得以通过其起源知识背景得到丰富和记录，进而得到恰当的解释。
