SourcePassport is an independent publication. Its standard is practical: distinguish evidence from interpretation, show the strongest available sources, and say plainly when a subject is still changing.
Topic selection
Coverage follows material changes in product identity, provenance, traceability, digital product passports, circular systems, standards, and regulation. A topic is selected for its likely usefulness to people designing, operating, governing, or understanding product information—not because it is commercially promoted.
Sources and verification
Primary sources are preferred: legislation, regulator and government publications, official standards material, and documents published by the organisations responsible for the systems discussed. Secondary material may help locate a question, but it should not replace the authoritative record when that record is available.
Evolving regulation
Product regulation develops through legislation, delegated and implementing acts, standards, guidance, working plans, and product-specific measures. Articles identify the date and scope of the sources used. Readers should confirm current obligations in the applicable jurisdiction; SourcePassport does not provide legal or compliance advice.
Analysis and fact
Statements about enacted rules, published standards, and documented system behaviour are treated as factual claims and sourced accordingly. Forecasts, design principles, and interpretations are presented as analysis. Certainty is not implied where evidence, implementation, or policy remains unsettled.
Corrections
Material errors should be corrected promptly and the article update date changed when the correction affects meaning. Clarifications and routine copy edits may be made without a separate notice. Correction requests can be sent to sourcepassport@outlook.com with the article, disputed passage, and supporting primary source.
Commercial relationships
Coverage is not sold and commercial relationships do not purchase an editorial conclusion. If commissioned, sponsored, affiliate, or otherwise commercially connected work is introduced, that relationship will be disclosed clearly on the relevant page.
Assisted research and review
Research and drafting may use software-assisted tools to organise material, test structure, or identify questions. Publication remains subject to human editorial review. Tools are not treated as sources; factual claims must resolve to the cited underlying record.
Publication and update dates
Every article displays its original publication date. An Updated date appears when a later editorial review materially changes sourcing, factual context, or meaning. Source access dates describe when the linked record was last checked for that article.
