Repository containing the developing of the RAMI vocabulary. This semantically enriched data model is based on the Plattform Industrie 4.0 specification Details of the Asset Administration Shell - Part 1. This repository provides an RDF version of the specification,
The ontology itself is contained in AAS-Ontology_2.0.ttl. You can find a visualization of the latest version can be created using the WebVOwl API.
The mapping folder contains a template of RML TripleMaps for Asset Administration Shell documents in XML. A mapping from JSON to RDF is not yet included. In addition, an example mapping file for a Raspberry Pi demo AAS (see examples) in various serializations is supplied.
The schema files are encoded as SHACL shapes.
The derivation of new facts (see reasoning) can be implemented using N3 rules as specified by Linked Data-Fu.
Although the ontology and all the other supplied files can be displayed by any text editor, Protege is the tool of choice. As previously mentioned, WebVOwl is a great service to create visualizations.
In order to execute the mapping, clone and build the RML Mapper.
java -jar rmlmapper-4.3.3-r95.jar -v -m AssetAdministrationShell_examples/Raspberry_Pi_3b_plus/aasx/iais_fraunhofer_de_en_aas_examples/iais_fraunhofer_de_en_aas_examples_raspberry_pi_3b_plus.aas.xml -s turtle -o output-file.ttl
The SHACL validation process requires the installation of the TopBraid SHACL API

The N3 reasoning rules can be applied through Linked Data-Fu:
