Introduction

This project contains an implementation of SHACL in Scala.

Installation and compilation

The project uses sbt for compilation as well as Java 1.11.

  • sbt test compiles and runs the tests

Usage

Once compiled, the program can be run as a command line tool. It is possible to run the program inside sbt as:

Validating RDF data with SHACL

Example:

sbt "run --data examples/shacl/good1.ttl 
         --engine ShaClex"

Interactive mode with sbt

It is usually faster to run the sbt command, which opens the interactive sbt shell and inside that shell, execute the different commands.

$ sbt
... several information about loading libraries
sbt> run -d examples/shacl/good1.ttl --engine ShaClex  

Binary mode

The fastest way to run Shacl-s is to compile the code and generate a binary. The following command:

$ sbt universal:packageBin
...generates the file...
target/universal/shacl-s-N.N.N.zip

which contains the compressed binary code.

Implementation details

  • The engine is based on purely functional concepts using the cats library

Compatibility tests

The current implementation passes all shacl-core tests. In order to generate the EARL report, run:

$ sbt 
[...]
sbt:shaclex> project shacl 
sbt:shacl> testOnly es.weso.shacl.report.ReportGeneratorCompatTest

Publishing to OSS-Sonatype

This project uses the sbt ci release plugin for publishing to OSS Sonatype.

Full Library Releases
  1. Push a tag and watch the CI do a regular release
  2. git tag -a v0.1.0 -m "v0.1.0"
  3. git push origin v0.1.0 Note that the tag version MUST start with v.

More information

  • More information about SHACL can be read in the Validating RDF data co-authored by one of the authors.
  • This project was originally part of SHaclEx but we decided to modularize that project and keep the SHACl implementation in its own repository.
  • An online demo based on this library is available at http://rdfshape.weso.es.
  • Another online demo based on this library customized for Wikidata is available at http://wikishape.weso.es.
  • This project was based on ShExcala which was focused on Shape Expressions only.
