Understand where information comes from.
The directory is an editorial selection; guides are practical methods to adapt to a project. These distinctions help you use the information at the right level of confidence.
Directory inclusion and evidence
Entries distinguish providers, directories, guides and reference resources. A listing gives an identifiable source and describes its role. It does not establish membership, endorsement, certification, availability or a ranking. Some resources may belong to the same ecosystem; compare alternatives against your own brief rather than treating the order as a recommendation.
Before appointing a provider, verify its legal identity, the person carrying out the work, relevant evidence, scope, exclusions and contractual terms. Before reusing data, inspect the specific dataset’s publisher, licence, period, coverage and access requirements. A catalogue page may be public while its data requires authorisation.
Contextual resources
Project guides also include links to relevant sites in the AR ecosystem. These blocks explain a specific use, distinguish providers from private directories and guides, and identify French-only destinations on English pages. They supplement the practical method; institutional and technical references remain the sources for rules and standards.
What a link-check date means
A link-check date records whether an automated request could reach the published address. It is distinct from the publisher’s data-update date and from an editorial verification of every statement. A successful response can still redirect to a different topic; automated checks must therefore be interpreted with the page content.
Some publishers block automated requests. “Automated check not confirmed” means the check was inconclusive, not that the organisation has disappeared. Follow the source directly and use its own contact or documentation to resolve the question.
Reference material and practical synthesis
Guides link to primary material where a definition, technical threshold or rule requires verification. Practical worksheets add an editorial method: actions, evidence and decisions to discuss with the responsible person. They are not individual legal advice, compliance certifications or a report on your organisation.
Distinguish documented thresholds from internal objectives. A benchmark requires a stated population, period and method; a suggested target must be adapted to the service. Examples should identify their assumptions and must not be mistaken for observed market figures.
Illustrations and organisation marks
Editorial scene images are AI-generated illustrations of the topics discussed. They do not identify network members, clients or actual events. Each photograph is assigned to one editorial subject and its translation. It may appear again in a linked preview of that subject, but is not reused across unrelated pages or successive cards. Photographs are stored in responsive WebP variants and identified as AI-generated in their alternative text.
A mark next to a resource identifies it visually and does not indicate a partnership. Where a usable organisation mark is unavailable, a neutral letter or symbol can be displayed. The name and destination remain the reliable identification cues.
French and English versions
The language switch links to the equivalent page when available. French and English pages cover the same topics, with wording adapted to each language.
Report a correction with evidence
Send the affected page URL, the entry or statement, the suggested correction and a primary source. For an image, include the filename or page location and the issue with identity, rights or relevance. Please avoid sending passwords, access tokens or unnecessary personal data.
A useful report distinguishes a factual error from a service request. A provider’s own site is the source for its current services; an official publisher is the source for a dataset or reference framework.
