Research to the question
Research is scoped to the knowledge being prepared. Work stops when enough reliable evidence exists to publish the material correctly; sources are not added simply to increase a citation count.
Use the strongest appropriate source
Official regulations, standards-body metadata, original research, government publications and scheme-owner documentation are preferred when they directly govern a claim. Reputable technical syntheses and institutions support explanation where primary evidence is not the best fit.
Register and resolve evidence
Sources used as evidence receive stable Source IDs. Articles reference those records rather than copying source metadata, which keeps titles, publishers, versions and links consistent across the site.
Separate explanation from reusable facts
Ordinary editorial explanation may be supported directly by sources. Reusable structured facts receive stable Fact IDs and preserve their source relationships, units, conditions and context where applicable.
Verify what is published
Claims present in a draft are checked against their cited evidence. Numerical and time-sensitive material is reviewed with its method, geography, period, units and uncertainty in view. Credible contradictions are resolved, scoped or held back.
Review and update progressively
Versioned, regulatory, market and certification knowledge is reviewed more often than stable definitions. A changed source version, an expired review date or credible contradictory evidence can trigger re-evaluation.
