RDF representation of 2017 edition of International Chronostratigraphic Chart (Geologic Timescale)

A set of RDFgraphs representing the International [Chrono]stratigraphic Chart, comprising Turtle serializations of data from the 2017-02 version, along with updated ontologies that define the structure of the data. \n\nThe Geological Timescale Model is aligned with the W3C OWL-Time ontology https://www.w3.org/TR/owl-time/ for the temporal topology, with OGC GeoSPARQL http://www.opengeospatial.org/standards/geosparql for location data, and with the W3C SOSA/SSN ontology for samples.\n\nThe content of the vocabulary matches the 2017-02 International Chronostratigraphic Chart. \nLineage: Original data scraped from the website of the International Commission for Stratigraphy, http://www.stratigraphy.org Transcribed into RDF by Cox & Richard. Multilingual labels entered by SMR and Marshall Ma (RPI - now University of Idaho)

本数据集为一组表征国际年代地层表（International Chronostratigraphic Chart）的RDF图（RDF graph），包含2017-02版本数据的Turtle序列化（Turtle）文件，以及用于定义该数据结构的更新版本体。

地质年代标尺模型（Geological Timescale Model）在时序拓扑结构上对齐了W3C OWL-Time本体（W3C OWL-Time ontology，https://www.w3.org/TR/owl-time/），位置数据采用OGC GeoSPARQL标准（OGC GeoSPARQL，http://www.opengeospatial.org/standards/geosparql），样本数据则适配W3C SOSA/SSN本体（W3C SOSA/SSN ontology）。

该词汇表的内容与2017-02版国际年代地层表完全一致。

数据溯源：原始数据爬取自国际地层委员会（International Commission for Stratigraphy）官网 http://www.stratigraphy.org，由Cox与Richard转录为RDF格式；多语言标签由SMR与Marshall Ma（原隶属于RPI，现任职于爱达荷大学（University of Idaho））录入。
