Methodology & Data Governance

SECTION 01

What Cross-Standard does — and does not do.

Cross-Standard is an informational index. It helps engineers, procurement teams, and compliance managers understand which standards apply across different jurisdictions and how they relate to each other. It is not a certification authority, a legal counsel, or a replacement for official sources.

What we do

• Index cross-border regulatory and standards requirements with source citations.
• Provide gap-comparison tables showing where two or more jurisdictions' requirements differ.
• Link directly to official government portals, standards bodies, and primary sources.
• Monitor official sources monthly and publish a public change log when indexed content is updated.
• Flag items that have not yet passed human verification with a visible [UNVERIFIED] tag.

What we do not do

• We do not host or reproduce the full text of any standard or regulation protected by copyright.
• We do not issue pass/fail certification conclusions or compliance verdicts on products or companies.
• We do not replace the advice of qualified lawyers, registered testing laboratories, or competent authorities.
• We do not accept payment from standards bodies, governments, or vendors in exchange for inclusion or editorial treatment.
• We do not guarantee that indexed content is current at the moment of any given user's access — verify at the official source before acting.

SECTION 03

Review SOP: AI-assisted extraction, human verification.

Cross-Standard uses AI to accelerate the extraction of structured fields from source documents. AI assistance is a productivity tool, not an editorial authority. The following rules govern every data row.

1. AI-assisted extraction is assistive only. AI tools are used to draft structured records (standard number, title, scope, applicable markets, source URL, effective date) from official documents. These drafts are not published as verified.
2. Key fields get double human verification. The fields that carry the highest compliance consequence — applicable market scope, effective date, mandatory vs. voluntary status, and the official source URL — are independently verified by two human reviewers before a row is marked as verified.
3. Uncertain items are tagged [UNVERIFIED]. Any field where the reviewer is uncertain of the answer, or where two reviewers disagree, is tagged [UNVERIFIED] in the published table. The tag is visible to users, not hidden.
4. Pages with any unverified row stay noindex. If a comparison page contains one or more [UNVERIFIED] rows, the page carries a noindex robots directive until all rows on that page have been verified. This prevents unverified content from appearing in search results.
5. Every published row shows its provenance. Source URL, access date (the date we retrieved the document), and a "last verified" date are recorded for each row and displayed in the table.

SECTION 04

Change monitoring and the public change log.

Standards and regulations change. Treating indexed data as permanently valid is a compliance risk. Cross-Standard maintains an active monitoring programme to detect and propagate changes.

• Monthly source checks. All indexed official sources are checked against their issuing body's publication catalogue or gazette at least once per calendar month. Changes to version numbers, effective dates, or mandatory status trigger a review workflow.
• High-risk change flagging. Where a change affects mandatory compliance status or a product recall/withdrawal notice, the affected page is flagged as requiring expedited review, typically within 5 working days. The comparison table row is temporarily marked [UNDER REVIEW].
• Public change log. Every update to an indexed row — new version, scope correction, source URL change, retirement of a superseded standard — is recorded in the public change log at /standard/changelog.html. The log shows the date, the affected standard, the nature of the change, and the previous value.
• No silent updates. We do not silently update table cells. Every substantive change to a data field is accompanied by a change log entry and a bump to the "last verified" date on the affected row.

SECTION 05

Correction policy.

Cross-Standard depends on the accuracy of its data. Errors found by users are treated as high-priority information, not as threats. We ask anyone who spots an inaccuracy to report it.

• Report via the dedicated form. Use /standard/report-error.html to submit a correction. Please include the affected page URL, the specific field, what you believe to be wrong, and a reference to the official source that supports the correction.
• Acknowledgement within 48 hours. Every submitted correction receives an acknowledgement within 48 hours. We will confirm whether an investigation has been opened or, if the reported value is already correct, explain why.
• High-risk corrections prioritised. Reports that allege an error in mandatory-compliance scope, market applicability, or effective date are treated as high-risk and escalated for expedited review within 1 working day.
• Corrections published in the change log. Every accepted correction is recorded in the public change log with a note that it originated from a user report. We do not erase errors; we document them.
