Crystalline materials, such as metals and semiconductors, nearly always contain a special defect type called dislocation. This defect decisively determines many important material properties, e.g., strength, fracture toughness, or ductility. Over the past years, significant effort has been put into understanding dislocation behavior across different length scales via experimental characterization techniques and simulations. This paper introduces the dislocation ontology (DISO), which defines the concepts and relationships related to linear defects in crystalline materials. We developed DISO using a top-down approach in which we start defining the most general concepts in the dislocation domain and subsequent specialization of them. DISO is published through a persistent URL following W3C best practices for publishing Linked Data. Two potential use cases for DISO are presented to illustrate its usefulness in the dislocation dynamics domain. The evaluation of the ontology is performed in two directions, evaluating the success of the ontology in modeling a real-world domain and the richness of the ontology.

通过实验表征技术和模拟方法，本文引入了针对晶体材料中线性缺陷的概念和关系的缺陷本体论（DISO）。DISO采用自上而下的方法进行开发，从定义线性缺陷领域中最通用的概念开始，并对其进行进一步的细化。使用W3C最佳实践发布连接数据的持久URL发布了DISO。通过两个潜在的用例来说明DISO在缺陷动力学领域的实用性。对本体论的评估从两个方向进行，既评估本体论在建模现实领域方面的成功性，也评估本体论的丰富性。
