Today we are releasing SDO-Check, our schema.org-based semantic data testing tool!

SDO-Check is a free-to-use web-tool that enables the fast and simple verification of schema.org annotations. This latest addition to the semantify.it toolkit allows the input of a code-snippet or a web-page URL and shows the verification result in form of an interactive tree-visualization with details about all irregularities found. The verification is based on the latest version of the official schema.org vocabulary, common SEO practices, and recommendations from semantic web experts.

Features

   ∗ All markup formats of schema.org are supported (JSON-LD, RDFa, Microdata).

   ∗ Allows input of code-snippets (HTML and JSON-LD).

   ∗ Allows input of web-page URLs (also handles dynamically loaded structured data markup).

   ∗ Fully aligned with schema.org, since the verification happens dynamically with official vocabulary files.

   ∗ Three different error severities (Warning, Error, Critical Error).

   ∗ Visualization and detailed explanation of found errors.

Limitations

Although SDO-Check will continue to adopt more and more features, formats, and technologies that are related to schema.org, the tool focuses on those common patterns used in schema.org annotations on web-pages. Right now SDO-Check assumes that the only vocabulary used in the input annotation is schema.org and that a simple @context is used (in JSON-LD there could be unlimited variations, but we focus on the most readable, shortest and common used versions). There are some parts of the JSON-LD specification that are not fully supported yet, e.g. the use of @reverse, @graph, or typed values.

Future work

SDO-Check is actively being improved, you will find the newest changes in our changelog.
