GeoSPARQL is an important standard for the geospatial linked data community, given that it defines a vocabulary for representing geospatial data in RDF, defines an extension to SPARQL for processing geospatial data, and provides support for both qualitative and quantitative spatial reasoning. However, what the community is missing is a comprehensive and objective way to measure the extent of GeoSPARQL support in GeoSPARQL-enabled RDF triplestores. To fill this gap, we developed the GeoSPARQL compliance benchmark. We propose a series of tests that check for the compliance of RDF triplestores with the GeoSPARQL standard, in order to test how many of the requirements outlined in the standard a tested system supports. This topic is of concern because the support of GeoSPARQL varies greatly between different triplestore implementations, and the extent of support is of great importance for different users. In order to showcase the benchmark and its applicability, we present a comparison of the benchmark results of several triplestores, providing an insight into their current GeoSPARQL support and the overall GeoSPARQL support in the geospatial linked data domain.

GeoSPARQL 合规性基准

GeoSPARQL 是地理空间关联数据社区的重要标准，因为它定义了在 RDF 中表示地理空间数据的词汇表，定义了用于处理地理空间数据的 SPARQL 扩展，并为定性和定量空间推理提供支持。然而，社区缺少的是一种全面而客观的方法来衡量支持 GeoSPARQL 的 RDF 三元组中对 GeoSPARQL 的支持程度。为了填补这一空白，我们开发了 GeoSPARQL 合规性基准。我们提出了一系列测试来检查 RDF 三元组是否符合 GeoSPARQL 标准，以测试被测系统支持的标准中概述的要求的数量。这个话题值得关注，因为不同的三元组实现对 GeoSPARQL 的支持差异很大，并且支持的程度对于不同的用户非常重要。为了展示基准测试及其适用性，我们比较了几个三元组的基准测试结果，以深入了解它们当前的 GeoSPARQL 支持以及地理空间链接数据域中的整体 GeoSPARQL 支持。
