A practical project for curious people

Build a knowledge base your AI can trust

Choose any subject. Turn reliable sources into a small, linked knowledge bundle. Test what your AI knows. Then build an app that helps somebody else learn.

  • No prior coding or linked-data knowledge assumed
  • Free, static and usable with your choice of AI
  • Privacy and evidence decisions before upload
OKFOpen Knowledge Format: small Markdown files with machine-readable facts.
Semantic linkA named, directed connection with evidence — not just a clickable link.
GroundingGiving an AI the relevant evidence and checking that its answer stays inside it.
MCPModel Context Protocol: an optional way for an AI to request bounded context.

Eight small stages, one useful result

Each stage repeats the same rhythm: explain, inspect a worked example, do one task, check it, then recall what mattered. You can stop after any checkpoint and return later.

  1. 01

    Choose

    Pick a subject small enough to finish and name who it should help.

    Project brief30–45 min
  2. 02

    Question

    Write the questions your bundle and app must answer before collecting data.

    Question set45 min
  3. 03

    Research

    Find sources and decide authority, rights, privacy, freshness and gaps.

    Source ledger1–3 hours
  4. 04

    Model

    Give things stable identities and add only relationships you can explain and evidence.

    Concept map1–2 hours
  5. 05

    Build

    Author a small OKF 0.2 bundle, then use exact checks instead of guesswork.

    Valid bundle1–3 hours
  6. 06

    Explore

    Use Reader, Search, Links, Graph, Timeline and Inspect to find defects.

    Journey receipt45–90 min
  7. 07

    Ground

    Connect your AI and compare its answers with questions you held back.

    Evaluation results1–2 hours
  8. 08

    Create

    Predict, run, inspect and modify working code before making your own learning UI.

    Tested app2–6 hours

Your subject, not ours

Start with something you care about

A useful first bundle is narrow enough to review yourself: roughly 15–60 concepts and 5–15 questions.

Local life

Public services, transport, planning, heritage or local history

Culture

Music, films, books, games, sport, art or a personal collection

Study

A course topic, scientific field, historical period or reading list

Work

Policies, APIs, guidance, research papers or organisational knowledge

Private

Your own notes or records — kept local unless you have a safe sharing decision

Working examples

Learn from real OKF bundles

These entries come from the governed registry. Their labels such as preview, candidate or bounded demonstrator are part of the evidence, not decoration.

Meet the primary learner

Sam is 18, curious and new to this

Sam can browse, edit files and ask an AI for help. They do not yet know data modelling, provenance or deployment. They need a visible result early, plain language, low-cost tools, safe choices and a clear definition of “done”.

“Show me why this idea helps my subject, let me try it on a real example, and give me a check I can trust.”
Read Sam’s complete persona and user stories

One format, many kinds of work

The same Explorer must expose both value and limits for different domains.

Data journalist

Find the exact ONS product, geography and vintage without confusing near-neighbours.

Open-data analyst

Inspect CKAN publishers, licences and resources without assuming catalogue quality.

Integration developer

Discover government APIs, then verify the real contract and access model.

Legal or policy researcher

Trace works, versions, jurisdictions and official provisions without turning discovery into advice.

Heritage educator

Create a source-backed local trail while keeping synthetic examples visibly separate.

Service designer

Connect guidance, life events and organisations without inventing eligibility or authority.

Your AI is a collaborator, not your evidence

Understand, apply, create — then verify

Understand

Ask where an answer came from

Learn identities, sources, dates, rights and uncertainty before asking the AI to make anything.

Apply

Compare expected and observed answers

Hold questions back, require record citations and count unsupported or near-neighbour answers.

Create

Read and change working code

Predict, run, investigate and modify a starter before using AI to create your personal interface.
