The Lexical Grid (LexGrid) project is an on-going community-driven initiative coordinated by the Mayo Clinic Division of Biomedical Statistics and Informatics (BSI). It provides a common terminology model to represent multiple vocabulary and ontology sources as well as a scalable and robust API for accessing such information. While successfully used and adopted in the biomedical and clinical community, an important requirement is to align the existing LexGrid model with emerging Semantic Web standards and specifications. This paper introduces the LexRDF model, which maps the LexGrid model elements to corresponding constructs in W3C specifications such as RDF, OWL, and SKOS. Our mapping specification successfully used W3C standards to represent most of the existing LexGrid components, and those that did not map point out issues in the existing specifications that the W3C may want to consider in future work. With LexRDF, the terminological information represented in LexGrid can be translated to RDF triples, and therefore allowing LexGrid to leverage standard tools and technologies such as SPARQL and RDF triple stores.
词汇网格（LexGrid）项目是由梅奥诊所生物医学统计与信息学部（BSI）协调的一个正在进行的社区驱动型计划。它提供了一个通用术语模型来表示多个词汇表和本体源，以及一个用于访问此类信息的可扩展且强大的应用程序编程接口（API）。虽然LexGrid在生物医学和临床社区中得到了成功应用和采用，但一个重要的要求是使现有的LexGrid模型与新兴的语义网标准和规范保持一致。本文介绍了LexRDF模型，该模型将LexGrid模型元素映射到W3C规范（如RDF、OWL和SKOS）中的相应结构。我们的映射规范成功地使用W3C标准来表示大多数现有的LexGrid组件，而那些未映射的组件则指出了W3C在未来工作中可能需要考虑的现有规范中的问题。通过LexRDF，LexGrid中表示的术语信息可以转换为RDF三元组，从而使LexGrid能够利用诸如SPARQL和RDF三元组存储等标准工具和技术。
