-# TopBraid SHACL API
+# TopBraid SHACL API Extended
 
-**An open source implementation of the W3C Shapes Constraint Language (SHACL) based on Apache Jena.**
+**This is a fork of the [TopBraid SHACL API](https://github.com/TopQuadrant/shacl), an open source implementation of the W3C Shapes Constraint Language (SHACL) based on Apache Jena.**
 
-Contact: Holger Knublauch ([email protected])
+Starting from [SHACL API v1.4.0](https://github.com/TopQuadrant/shacl/releases/tag/v1.4.0), the SHACL-JS support was removed to avoid Nashorn issues.
+
+This fork brings the SHACL JavaScript Extensions (SHACL-JS) features back by leveraging GraalVM and its Polyglot APIs. Not only the SHACL-JS features are brought back but new extensions are introduced, such as the SHACL Python Extensions (SHACL-Py).
 
-Can be used to perform SHACL constraint checking and rule inferencing in any Jena-based Java application.
-This API also serves as a reference implementation of the SHACL spec.
 
 Coverage:
 * [SHACL Core and SHACL-SPARQL validation](https://www.w3.org/TR/shacl/)
 * [SHACL Advanced Features (Rules etc)](https://www.w3.org/TR/shacl-af/)
-* [SHACL JavaScript Extensions](https://www.w3.org/TR/shacl-js/)
 * [SHACL Compact Syntax](https://w3c.github.io/shacl/shacl-compact-syntax/)
+* [SHACL JavaScript Extensions](https://www.w3.org/TR/shacl-js/)
+* SHACL Python Extensions
 
-See [SHACL-JS](https://github.com/TopQuadrant/shacl-js) for a pure JavaScript implementation.
-
-The same code is used in the TopBraid products (currently aligned with the TopBraid 6.3 release).
-
-Feedback and questions should become GitHub issues or sent to TopBraid Users mailing list:
-https://groups.google.com/forum/#!forum/topbraid-users
-Please prefix your messages with [SHACL API]
-
-To get started, look at the class ValidationUtil in
-the package org.topbraid.shacl.validation.
-There is also an [Example Test Case](../master/src/test/java/org/topbraid/shacl/ValidationExample.java)
-
-## Application dependency
-
-Releases are available in the central maven repository:
-
-```
-<dependency>
-  <groupId>org.topbraid</groupId>
-  <artifactId>shacl</artifactId>
-  <version>*VER*</version>
-</dependency>
-```
-## Command Line Usage
-
-Download the latest release from:
-
-`https://repo1.maven.org/maven2/org/topbraid/shacl/`
-
-The binary distribution is:
-
-`https://repo1.maven.org/maven2/org/topbraid/shacl/*VER*/shacl-*VER*-bin.zip`.
-
-Two command line utilities are included: validate (performs constraint validation) and infer (performs SHACL rule inferencing).
-
-To use them, set up your environment similar to https://jena.apache.org/documentation/tools/ (note that the SHACL download includes Jena).
-
-For example, on Windows:
-
-```
-SET SHACLROOT=C:\Users\Holger\Desktop\shacl-1.0.0-bin
-SET PATH=%PATH%;%SHACLROOT%\bin
-```
-
-As another example, for Linux, add to .bashrc these lines:
-
-```
-# for shacl
-export SHACLROOT=/home/holger/shacl/shacl-1.0.0-bin/shacl-1.0.0/bin
-export PATH=$SHACLROOT:$PATH 
-```
-
-Both tools take the following parameters, for example:
-
-`shaclvalidate.bat -datafile myfile.ttl -shapesfile myshapes.ttl`
-
-where `-shapesfile` is optional and falls back to using the data graph as shapes graph.
-
-Currently only Turtle (.ttl) files and SHACL Compact Syntax (.shaclc) files are supported.
-
-The tools print the validation report or the inferences graph to the output screen.
