Nexus Foundations (101)

1) Scope & Goals

Purpose. Make 101-level learning the universal gateway to all sectors (health, finance, water, food, energy, cities, technology, nature, policy).
Design. Small, verifiable units that: (a) teach common language and methods, (b) map cleanly to standards and job roles, (c) produce artifacts with provenance, (d) stack into sector Micro-Certificates (MC) and onward.

Areas covered across all units: Science Policy, Just Transition, Resilience Building, Anticipatory Action, DRR, Biodiversity & Ecosystems.

---

2) Tier & Workload Rules (101 Layer)

• NB (Nanobadge): 2–4 h (0.2–0.4 NCU). Quiz + one artifact.
• MB (Microbadge): 6–8 h (0.6–0.8 NCU). Mini-project + quiz.
• MC (Micro-Certificate): 12–20 h (1.2–2.0 NCU). Lab + scenario + proctored assessment.

ECTS advisory: 1 NCU ≈ 0.33–0.40 ECTS.
Renewal: invited on MAJOR revision via targeted delta exam or artifact refresh.

---

3) Codes, Versions & Catalog

• Immutable codes: CORE-NB-1xx, CORE-MB-1xx, CORE-MC-12x/12y.
• Revision: rev: YY.MM.P (major/minor/patch).
• Permalinks: /academy/courses/<code> (latest) + ?rev= for specific.
• Status: active | deprecated | superseded with redirects and successor mapping.

---

4) Cross-Cutting Requirements (all units)

• Metadata (mandatory): code, rev, hours/NCU, 3–6 outcomes, standards tags, competency tags (ESCO/SFIA), languages, accessibility flags, assessment blueprint, artifact license (SPDX), provenance (W3C PROV).
• Credentialing: Open Badges 3.0 and W3C VC; hashed recipient; public status list; hash-only on-chain anchoring.
• Accessibility & i18n: WCAG 2.2 AA; EN/FR/ES/AR; RtL support; transcripts/captions.
• Assessment blueprint:
  • NB → QZ (10–12 items) 40% + artifact 60%
  • MB → Quiz 30% + mini-project 70%
  • MC → Lab 50% + scenario brief 20% + proctored QZ/OD 30% (reliability target α ≥ 0.75)
