Source modelsChoose the owner of the answer.
A source model describes who maintains a route and what that relationship can establish—not whether the resource, provider, product, or answer is good.
Stitch Authority

- What it can establish
- The current interface, calculation basis, cited evidence, and stated limits of a page maintained on this site.
- What it cannot establish
- Project fit, legal compliance, certificate status, provider quality, or a third party’s current terms.

- What it can establish
- The identity, scope, status, or record fields that the responsible registry currently exposes.
- What it cannot establish
- Product or shipment coverage beyond the displayed record, provider quality, commercial fit, or facts outside the registry’s scope.
- Check next
- Match names, identifiers, dates, scope, products, sites, and transaction-level evidence to the exact decision you are making.
Government guidance
You need the responsible public body’s current starting point for a law, label, product rule, safety duty, or jurisdiction.
- What it can establish
- What the responsible body currently says about the rule, jurisdiction, covered subject, and official route to further material.

- What it can establish
- The records and inclusion context the public body currently publishes for its program or jurisdiction.
- What it cannot establish
- A complete market census, current capacity, availability, provider quality, or project suitability.
- Check next
- Confirm current activity, exact service, eligibility, location, capacity, terms, and fit directly with the listed organization.
Industry organization
You need a field-specific technical reference, training route, member list, supplier population, or sector guide.
- What it can establish
- The organization’s current stated scope and the reference, program, or directory population it publishes.
- What it cannot establish
- Independent assessment, universal sector coverage, member quality, or suitability unless the source documents a separate assessment.
- Check next
- Inspect the inclusion model, constituency, commercial relationships, date, and project-specific evidence before relying on a listed route.
First-party platform
You need to understand or use a platform, database, software product, learning product, or service from the operator itself.
- What it can establish
- The operator’s current stated scope, features, access model, workflow, and published terms.
- What it cannot establish
- Neutrality, completeness, third-party record accuracy, output correctness, continued availability, or usefulness for your project.
- Check next

Community database
You need broad discovery, user-contributed records, project examples, repair knowledge, or community-maintained cross-links.
- What it can establish
- What the community database currently publishes and how its contributors organize or extend the collection.
- What it cannot establish
- Representative consensus, original-source accuracy, current availability, provider quality, or provenance when a record does not supply it.

Open-source project
You need software whose documentation, repository, license, and implementation can be inspected or adapted.
- What it can establish
- The project’s published code, documentation, license, release state, contribution model, and stated workflow.
- What it cannot establish
- Output correctness, security, maintenance continuity, support, fit, grading quality, or production readiness for your use.

Use a recordThe model narrows the source. The record narrows the decision.
- Choose the job.Start with what you need to decide, make, find, learn, repair, source, or check.
- Choose the source model.Match the owner of the information to the kind of fact you need.
- Read the record boundary.Check access, location, evidence, review date, and “What this record does not prove.”
- Confirm at the source.Verify the project-specific facts, current terms, scope, status, or provider details before acting.
