开放教育资源目前正变得越来越多地从多种来源，因此在许多不同的方式注释。自然产生的互操作性问题往往可以通过元数据描述的语义化来解决，同时加强资源的知识价值。SKOS可以是一个坚实的连接点，通过引用语义词库，为主题描述提供标准词汇表。我们提出了增强和维护教育资源的元数据的学习对象本体的形式，并介绍了学习对象本体库的概念，可以帮助他们的出版，发现和重用。与此同时，链接到叙词表数据集和上下文化的源将学习对象与链接的数据相互关联，并将它们暴露给Web of Data。我们在当代本体管理工具（如WebProtégé）的基础上构建了一组扩展和工作流程，使其适合作为学习对象本体库。所提出的方法和实施可以帮助图书馆和大学发现，管理和整合开放教育资源，并加强现有的课程。
Open educational resources are currently becoming increasingly available from a multitude of sources and are consequently annotated in many diverse ways. Interoperability concerns that naturally arise can often be resolved through the semantification of metadata descriptions, while at the same time strengthening the knowledge value of resources. SKOS can be a solid linking point offering a standard vocabulary for thematic descriptions, by referencing semantic thesauri. We propose the enhancement and maintenance of educational resources’ metadata in the form of learning object ontologies and introduce the notion of a learning object ontology repository that can help towards their publication, discovery and reuse. At the same time, linking to thesauri datasets and contextualized sources interrelates learning objects with linked data and exposes them to the Web of Data. We build a set of extensions and workflows on top of contemporary ontology management tools, such as WebProtégé, that can make it suitable as a learning object ontology repository. The proposed approach and implementation can help libraries and universities in discovering, managing and incorporating open educational resources and enhancing current curricula.
