Data Sources & Attributions

Last updated: July 6, 2026

Compliome's answers are grounded in public regulatory, legal, and biomedical data. We are grateful to the organisations below for making it openly available. Where a source requires attribution or share-alike terms, we credit it here and preserve the applicable licence.

1. Regulatory & legal sources

Official publications of government bodies and regulators, used under their public-sector terms:

  • U.S. Food & Drug Administration (FDA) — the electronic Code of Federal Regulations (eCFR, Title 21), FDA guidance documents, warning letters, openFDA (drug labels and aggregate FAERS adverse-event counts), and DailyMed Structured Product Labeling. U.S. Government works — public domain.
  • ClinicalTrials.gov (U.S. National Library of Medicine) — trial registrations. Public domain.
  • European Medicines Agency (EMA) — the European medicines data tables. © European Medicines Agency; reproduced with acknowledgement.
  • EU Clinical Trials — CTIS (Clinical Trials Information System) and the legacy EU-CTR / EudraCT register. © European Union.

  • Swissmedic (Switzerland) — the list of authorised medicines. © Swissmedic.
  • UK MHRA / GOV.UK — UK medicines and regulatory guidance. Contains public sector information licensed under the Open Government Licence v3.0.

2. Biomedical & chemistry datasets

Open scientific datasets that enrich the knowledge graph (drug targets, chemistry, pathways, protein interactions, and disease associations). We reproduce each licence and its required attribution:

  • DrugCentral — drug → target and ADME data. Data from DrugCentral (drugcentral.org), licensed CC BY-SA 4.0.
  • ChEMBL (EMBL-EBI) — bioactivity data. Data from ChEMBL (ebi.ac.uk/chembl), licensed CC BY-SA 3.0.
  • ChEBI (EMBL-EBI) — chemical entities of biological interest. ChEBI (ebi.ac.uk/chebi), CC BY 4.0.
  • Reactome — biological pathways. Reactome (reactome.org), CC BY 4.0.
  • UniProt — protein function and names. UniProt, CC BY 4.0.
  • STRING — protein–protein interactions. STRING, CC BY 4.0.
  • Open Targets — target–disease associations, tractability and safety. Open Targets, CC0 1.0 (public domain dedication).
  • PubChem (NCBI) — chemical structures and identifiers. Public domain.

The CC BY-SA share-alike terms apply only to the DrugCentral- and ChEMBL-derived data itself; they do not extend to Compliome's software, other data, or the answers we generate. Licence texts: CC BY-SA 4.0, CC BY-SA 3.0, CC BY 4.0, CC0 1.0, OGL v3.0.
