WHODrug as linked data

WHODrug contains information on over 2.6 million medicinal products and linking this data using semantic web technologies could enable more powerful uses of the data. Publishing WHODrug as linked data using URIs and RDF could allow linking to other data sources, sharing information more easily, and running queries over the graph of linked data. Delivering the data and schema as linked open data through resolvable URIs and SPARQL endpoints is an approach worth further exploration to maximize the potential of the WHODrug dataset.
WHODrug as linked data
- 1. WHODrug as Linked Data - an idea worth further exploration? Magnus Wallberg magnus.wallberg@who-umc.org @cmwallberg
- 4. Uppsala Monitoring Centre Inspire. Engage. Transform. Uppsala Monitoring Centre (UMC) advances the science of pharmacovigilance and inspires patient safety initiatives all over the world. As an independent, non-profit foundation, we engage stakeholders who share our vision and collaborate to build a global patient safety culture. As a leader in the research and development of new scientific methods, we explore the benefits and risks of medicines to help minimise harm to patients, and offer products and services used by health authorities and life-science companies worldwide. For almost 40 years, we have provided scientific leadership and operational support to the WHO Programme for International Drug Monitoring.

- 21. The conceptual model as a linked data schema (RDF)
- 22. SPARQL Query
- 24. Describe the product composition http://data.who-umc.org/whodrug/composition/13500101
- 26. Moving forward Do nothing Deliver a schema – leave implementation to users (based on old text files) Deliver schema and data as RDF-files (version controlled) Deliver a Linked Data API with resolvable URIs (HTML, json-LD, RDF) SPARQL-endpoint
