| 中文简介: |  使用HTTP方法与RDF进行交互时，访问控制是公认的未解决问题。在文献中，身份验证和授权机制要么引入了不希望的复杂性（例如SPARQL和临时策略语言），要么依赖于基本的访问控制列表，从而导致有限的策略表示性。在本文中，我们展示了如何逐步转换基于Shi3ld属性的SPARQL端点的授权框架，以保护RDF上的HTTP操作。我们按步骤进行：从支持SPARQL 1.1图形存储协议开始，然后转向针对链接数据平台的SPARQL较少解决方案。我们证明了最终的授权框架提供了与基于SPARQL的授权框架相同的功能，包括仅采用语义Web语言。 |
| 课程简介: | Access control is a recognized open issue when interacting with RDF using HTTP methods. In literature, authentication and authorization mechanisms either introduce undesired complexity such as SPARQL and ad-hoc policy languages, or rely on basic access control lists, thus resulting in limited policy expressiveness. In this paper we show how the Shi3ld attribute-based authorization framework for SPARQL endpoints has been progressively converted to protect HTTP operations on RDF. We proceed by steps: we start by supporting the SPARQL 1.1 Graph Store Protocol, and we shift towards a SPARQL-less solution for the Linked Data Platform. We demonstrate that the resulting authorization framework provides the same functionalities of its SPARQL-based counterpart, including the adoption of Semantic Web languages only. |
