Abstract (30 sec). A beehive is a data system: noisy observations, seasonal dynamics, tight feedback loops. By treating photos, weather, and notes as first‑class, related entities (a graph), we turn anecdotes into evidence‑ready decisions. The same pattern hardens enterprise analytics: clearer lineage, less hand‑waving, more trust.

Overview (2 min) - **Problem.** Real‑world data arrives messy and context‑poor (images, timestamps, half‑remembered notes). - **Idea.** Model the *relationships* explicitly—photos ↔ conditions ↔ events—so patterns become queryable. - **Payoff.** Faster sense‑making (what changed, when, under what conditions), portable documentation, and governance that’s baked into the model—not tacked on.

1) From “piles of stuff” to a knowledge graph

Artifacts: photos (EXIF), weather snapshots, inspections, interventions, outcomes.
Relationships: observed_during, preceded_by, co‑occurs_with, causes, measured_at.
Result: you can ask joined questions: “Show me high‑humidity inspections within 24h of reduced foraging.”

Design mantra: Name the things; name the links; make both queryable.

Minimal entity set (adapt for any domain)

  • Observation (photo, note) → time, source, signals
  • Context (weather, location) → temp, humidity, lat/lon
  • Event (intervention, incident) → type, magnitude, target
  • Outcome (metric) → value, window

2) Governance you don’t have to remember

Governance isn’t a checklist—it’s a side‑effect of good modeling.

  • Lineage by construction. Every edge carries provenance (who/what/when).
  • Schema as communication. One diagram + short glossary beats 10 pages of prose.
  • Reproducibility guardrails. Lockfile + environment file + small, typed transforms.

Reusable checklist

  • Name & define entities/relations (one‑page glossary).
  • Capture provenance fields on ingest (source, version, timestamp, transform ID).
  • Store context next to observations (don’t lose weather/time/place).
  • Lock the environment (Poetry) and auto‑load secrets (.env + direnv).
  • Document one query per decision the system should support.

3) UX for analytics: show joins, not just charts

A single chart rarely answers “so what?”. Pair evidence trails with visuals:

  • A timeline that shows observations and events in one track.
  • An evidence table: claim → linked observations → provenance columns.
  • A compare view: “this week vs. last under similar conditions”.
Claim: "Reduced activity is humidity-related"
Evidence:
- 2024-08-13 07:10 photo → EXIF humidity 76% (NOAA) → less forager count vs. baseline
- 2024-08-14 07:15 photo → humidity 78% → similar reduction

4) Porting the pattern to enterprise analytics

  • Customer ops: Tickets ↔ changes ↔ incidents → defensible post‑mortems.
  • Marketing analytics: Creative ↔ segment ↔ outcome → fewer attribution myths.
  • Finance: Transaction ↔ control ↔ exception → auditable adjustments.

If you can’t draw the entities and relations cleanly, you can’t govern the system cleanly.

5) A tiny start (that scales)

  1. Pick one decision your team cares about.
  2. List the entities and edges that decision touches.
  3. Ingest a week of data with provenance fields.
  4. Build one evidence table and one timeline.
  5. Write the one‑page glossary. Repeat.
