This repository contains tools for a bidirectional Modelica-IFC-Translation.
- Concept presented at EG-ICE 2021: "Bidirectional coupling of Building Information Modeling and Building Simulation using ontologies"
- concept described in detail in PhD thesis (submitted for assesment, German): Simulation von Gebäude-Anlagentechnik in der BIM-basierten Planung energieeffizienter Gebäude - Anbindung von Modelica-Modellen an OpenBIM-IFC-Modelle mittels semantischer Technologien
- MoTTL-Transcriptor including example presented at EC3 2023 "Representing Modelica Models as Knowledge Graphs Using The MoOnt Ontology"
- BIM2SIM workflow will be presented at ECPPM 2024 (Sept 2024). A link for this paper will be published here, as soon as it is available: "BIM2SIM: Automated Generation of Modelica Models from IFC Files for HVAC Plants using Knowledge Graphs"
to clone this repository (including submodules) use
git clone --recurse-submodules https://github.com/ElisEck/MO-x-IFC`
Eight converters have been developed/published. The figure shows the input and output files (boxes) of each converter (green or magenta arrow).
this is a copy of the used binary from https://github.com/pipauwel/IFCtoRDF
This component transcribes Modelica packages to knowledge graphs. It was developed as a Java tool and is delivered as a *.jar.
- download the executable *.jar from XXX
- it contains all dependencies and can be run out of the box
- it can be executed on a JVM version 11 (or higher)
- run the following command to generate a turtle file representing some Modelica package (adapt the paths to your files)
java -Dpolyglot.engine.WarnInterpreterOnly=false -jar c:\MoTTL-Transcriptor-0.9-SNAPSHOT-jar-with-dependencies.jar -p "ex" -n "LBDCG_example" -t "knowledge graph representing the Modelica LBDCG_example package" -v "v1.0.1-1.0.0" -o "C:\output\path" --inputPath "c:\LBDCG_example"
you need to provided six parameters:
- inputPath i: path to directory containing the input package (package.mo, package.order) e.g. c:\LibEAS (without trailing slash), use quotes if whitespaces contained
- outputPath o: path to directory where the turtle file should be placed e.g. c:\TMP (without trailing slash), use quotes if whitespaces contained
- prefix p: ontology prefix e.g. "mbl" (without colon and quotes)
- ontologyLongName n: e.g. "Buildings" (no quotes necessary)
- ontologyTitle t: e.g. Modelica Buildings Library (v8.0.0) ontology
- ontologyVersion v: combined version number of Modelica package and the ontology v8.0.0-1.0.0
- example outputs (knowledge graphs in ttl serialization) for common libraries (AixLib, BuildingSystems, Modelica Buildings, Modelica Standard Library) are contained in the folder: ./src/main/resources/ontologies/8_ModelicaLibraries
- their native Modelica files are available on their respective github repositories
- an example input Modelica package is contained in the folder: ./src/test/resources/C_HeatPumpPlant
- the corresponding output is contained in the file: ./src/test/java/output/ex_20221215_1154_fullclean.ttl
Through maven this code depends primarily on:
- ANTLR 4.8
presented at EC3 2023 "Representing Modelica Models as Knowledge Graphs Using The MoOnt Ontology"
- MoOnt definition is given in this file: ./src/main/resources/ontologies/7_MoOnt/MoOnt.ttl
- the heat pump plant example (native Modelica Code) is given here: ./src/test/resources/C_HeatPumpPlant
- the corresponding output (knowledge graph in ttl serialization) is contained in the file: ./src/test/java/output/ex_20221215_1154_fullclean.ttl
- knowledge graphs in ttl serialization for common Modelica libraries (AixLib, BuildingSystems, Modelica Buildings, Modelica Standard Library) are contained in the folder: ./src/main/resources/ontologies/8_ModelicaLibraries
- python code to execute the queries described in section "Discussion and Result Analysis – Answering Competency Questions" are given here: ./test/EC3example_SPARQLqueries.py
- as discussed in the paper there are some implementation issues with CQ2, these are shown here: ./test/CQ2
- the outputs of these scripts are shown here (only excerpts are shown in the paper wrt page limitations): ./test/EC3example_SPARQLqueries_outputs.txt
