# SDM-RDFizer This project presents the SDM-RDFizer, an interpreter of mapping rules that allows the transformation of (un)structured data into RDF knowledge graphs. The current version of the SDM-RDFizer assumes mapping rules are defined in the [RDF Mapping Language (RML) by Dimou et al](https://rml.io/specs/rml/). The SDM-RDFizer implements optimized data structures and relational algebra operators that enable an efficient execution of RML triple maps even in the presence of Big data. SDM-RDFizer is able to process data from Heterogeneous data sources (CSV, JSON, RDB, XML).  The results of the execution of SDM-RDFizer has been described in the following research reports: - Enrique Iglesias, Samaneh Jozashoori, David Chaves-Fraga, Diego Collarana, and Maria-Esther Vidal. 2020.

In:Proceedings of the Workshop on Linked Data on the Web co-located with the 23rdInternational World Wide Web Conference (WWW 2014) # Projects where the SDM-RDFizer has been used The SDM-RDFizer is used in the creation of the knowledge graphs of EU H2020 projects and national projects where the Scientific Data Management group participates. These projects include: - iASiS (http://project-iasis.eu/): big data for precision medicine, based on patient data insights. The iASiS RDF knowledge graph comprises more than 1.2B RDF triples collected from more than 40 heterogeneous sources using over 1300 RML triple maps. - BigMedilytics (https://www.bigmedilytics.eu/): lung cancer pilot. 800 RML triple maps are used to create the lung cancer knowledge graph from around 25 data sources with 500M RDF triples. - CLARIFY (https://www.clarify2020.eu/): predict poor health status after specific oncological treatments - P4-LUCAT (https://www.tib.eu/de/forschung-entwicklung/projektuebersicht/projektsteckbrief/p4-lucat) - ImProVIT (https://www.tib.eu/de/forschung-entwicklung/projektuebersicht/projektsteckbrief/improvit) - PLATOON (https://platoon-project.eu/) - EUvsVirus Hackathon (April 2020) (https://blogs.tib.eu/wp/tib/2020/05/06/how-do-knowledge-graphs-contribute-to-understanding-covid-19-related-treatments/). SDM-RDFizer created the Knowledge4COVID-19 knowledge graph during the participation of the team of the Scientific Data Management group. By June 7th, 2020, this KG is comprised of 28M RDF triples describing at a fine-grained level 63527 COVID-19 scientific publications and COVID-19 related concepts (e.g., 5802 substances, 1.2M drug-drug interactions, and 103 molecular disfunctions). The SDM-RDFizer is also used in EU H2020, EIT-Digital and Spanish national projects where the Ontology Engineering Group (Technical University of Madrid) participates. These projects, mainly focused on the transportation and smart cities domain, include: - H2020 - SPRINT (http://sprint-transport.eu/): performance and scalability to test a semantic architecture for the Interoperability Framework on Transport across Europe. - EIT-SNAP (https://www.snap-project.eu/): innovation project on the application of semantic technologies for national access points. - Open Cities (https://ciudades-abiertas.es/): national project on creating common and shared vocabularies for Spanish Cities - Drugs4Covid (https://drugs4covid.oeg.fi.upm.es/): NLP annotations and metadata from more than 60,000 scientific papers about COVID viruses are integrated in a KG with almost 44M of facts (triples). SDM-RDFizer was used for creating this KG. # Installing and Running the SDM-RDFizer From PyPI (https://pypi.org/project/rdfizer/): ``` python3 -m pip install rdfizer python3 -m rdfizer -c /path/to/config/file ``` From Github/Docker: Visit the [wiki](https://github.com/SDM-TIB/SDM-RDFizer/wiki) of the repository to learn how to install and run the SDM-RDFizer.
