schemaorgstyle

schemaorgstyle is a style guide and set of best‑practice recommendations for implementing Schema.org structured data on websites. It was created by a community of web developers and data scientists who recognized the need for consistent, machine‑readable markup that is both accurate and easy to maintain. The guide focuses on formatting and naming conventions for JSON‑LD, Microdata, and RDFa representations, providing clear examples for common entities such as Person, Organization, Product, and Event.

The style encourages the use of canonical property names, explicit language tags, and minimal nesting to improve parsing performance. It also outlines rules for handling optional and required properties, explains how to reference external identifiers like ISBN or GTIN, and recommends using the latest Schema.org version to take advantage of new terms. Developers can adapt the rules to their own project templates, and many popular content management systems have plugins that automatically generate schemaorgstyle‑compliant markup.

schemaorgstyle is maintained by Schema.org contributors in collaboration with the W3C and is periodically updated to reflect additions to the vocabulary. The guide includes versioning information and a changelog to help teams stay current. It is widely cited in academic papers on web search, SEO, and data interoperability, and has been adopted by major search engines as a reference for rich‑results eligibility. In practice, following schemaorgstyle can reduce markup errors, improve search‑engine visibility, and create a foundation for data exchange across platforms.
