Abstract

The paper describes a tool for validating and previewing instances of Schema.org JobPosting described in structured data markup embedded in web pages. The validator and preview was developed to assist users of Schema.org to produce data of better quality. The paper discusses the implementation of the tool and design of its validation rules based on SPARQL 1.1. Results of experimental validation of a job posting corpus harvested from the Web are presented. The validation’s findings indicate that publishers of Schema.org JobPosting data often misunderstand precedence rules employed by markup parsers and ignore case-sensitivity of vocabulary names.
