shaclex - SHACL/ShEx implementation

Introduction

shaclex is an implementation of SHACL and ShEx using a purely functional approach based on Monads.

shaclex is implemented in Scala which means that it can be used in any JVM environment.

We are currently working on adapting the implementation to ScalaJS so it could also be run within Javascript environments

shaclex can be used as:

• An independent command line tool
• A jar library that can be invoked from Scala or Java programs
• Deployed as standalone Web application: see shaclex.herokuapp.com

Features

• SHACL Features
• ShEx Features and EARL implementation report
• List of issues

More information is available at shaclex wiki.
