Having rules and ensuring that data adheres to them is necessary in order to encode best practices for data creators and to guarantee data quality for the applications that use it. Until now, there wasn’t a semantic standard for defining rules or for checking conformance of data to rules. Organizations used proprietary approaches or simply stated their rules on paper.

SHACL (Shapes Constraint Language), the new W3C standard, addresses this problem. SHACL offers rich, flexible notations for expressing practically any rule. This presentation will:

  • Introduce SHACL and the motivations behind its creation
  • Provide some examples of its use and its value
  • Examine the relation between SHACL, linked data, and the growing interest in “knowledge graphs”
  • Explore the support that SHACL brings to data governance

Irene Polikoff was a co-chair of the W3C SHACL Working Group and is now a co-chair of W3C SHACL Community Group. She will share with attendees not only SHACL’s features and capabilities, but will also discuss the rationale behind its design and recommend best practices for using SHACL. SHACL is a significant step towards making Linked Data more viable and usable in practical situations. Many people believe that SHACL will be a game changer in data governance and metadata management for data, datasets, and Big Data.
