This course provides a structured introduction to the Shape Constraint Language (SHACL), a W3C standard for validating RDF data. It is designed for learners who already have a solid understanding of RDF and SPARQL, as these technologies form the basis for working effectively with SHACL.

Throughout the course, we explore the core concepts of SHACL, including the definition and role of shapes, the use of targets to specify where constraints apply, and the distinction between node shapes and property shapes. We also cover how to define custom validation messages to improve feedback during data validation.

In the section on core constraint components, we dive into practical techniques for:

• Controlling the number of properties (cardinality constraints),

• Restricting the types of resources,

• Limiting literal values (e.g., strings, numbers, dates),

• Comparing resources to enforce consistency.

Upon completion, learners will be equipped to begin modeling SHACL shapes and validating RDF data in real-world applications. These fundamental SHACL constructs allow you to define clear expectations for your RDF data, detect structural issues early, and ensure consistency across datasets.
