Transparency & Data Governance

Data provenance, versioning policy, and governance standards for the International Sovereignty Index. For mathematical construction and computational architecture, see Methodology.

1. Data Sources & Provenance

All ISI scores are derived from publicly accessible datasets maintained by international statistical authorities. No proprietary, paywalled, or classified data is used in any axis computation.

Authority	Coverage	Axes
Eurostat	EU bilateral trade flows, energy statistics, national accounts, balance of payments	Energy, Financial, Technology, Critical Inputs, Logistics
UN Comtrade	International merchandise trade at HS commodity level	Technology, Critical Inputs, Logistics
SIPRI	Arms transfers database — Trend Indicator Values (TIV)	Defense
BIS	International banking statistics — bilateral financial positions	Financial
IEA	World energy statistics and balances	Energy

Specific dataset identifiers and retrieval parameters are documented on each axis detail page under “Data Sources & Channels.”

2. Versioning Policy

The ISI framework is versioned to ensure methodological traceability. All published outputs carry a framework version identifier and a reference window.

Current Versionv0.1

Version immutability. Published versions are frozen. Corrections are issued as errata.
Breaking changes. Changes to concentration formula, share computation, or classification thresholds require a major version increment.
Additive extensions. New axes or channels are added via minor version increments without retroactively altering existing scores.

3. Revision & Correction Procedures

The ISI maintains a strict separation between methodological corrections and data refreshes:

Data refresh. Source data is extracted at defined reference windows. New extraction windows produce new output artifacts but do not alter the methodology.
Errata. If a computational error is discovered in a published version, an erratum is issued describing the nature, scope, and impact of the correction.
Restatements. Restated scores replace prior outputs only when the original computation contained a demonstrable error. Restatements are documented with full change attribution.

4. Known Limitations

The following limitations apply to the current published version. For structural limitations of the computational model, see the Methodology page (Section 9).

Data vintage

Scores reflect the reference window stated on each page. They do not auto-update and may lag real-world shifts in supplier structures.

Channel coverage heterogeneity

Not all axes have the same number of data channels. Axes with fewer channels may be less robust against individual data quality issues.

Missing country-axis combinations

Some country-axis pairs are missing due to data unavailability. The composite is then computed over available axes only, which may affect cross-country comparability.

Source data discrepancies

Bilateral trade statistics may differ between reporter-side and partner-side records. The ISI uses reporter-side data exclusively. Mirror statistics are not cross-validated in v0.1.

5. Frontend Architecture Disclosure

All scores and classifications are computed server-side from documented data sources. The frontend interface displays published outputs without transformation. Rank orderings, deviation indicators, and cohort aggregate statistics displayed in the interface are derived computations from the backend-provided score set and are not independently scored.

6. Data Access & Export

Published ISI data is available for download in machine-readable formats. No registration or authentication is required.
