Provenance
Know where every record originates.
NEXORA / PUBLIC DATA FOUNDATION
NEXORA DATA STATUS
Public data. Provenance. Quality. Freshness
Follow every public evidence stream from official provider to bounded analytical use.
Public data · Derived indicators · Transparent methodology
What evidence can NEXORA support — and where are the limits
Quality
Inspect validation and coverage states.
Freshness
See when evidence was refreshed.
WHAT THE DATA SUGGESTS
Three findings to interpret with care
01OBSERVED
Operational coverage expanded without lowering the gate
R4 adds a frozen California annual aggregate from a bounded NSF Award Search query while retaining source and method boundaries.
02OBSERVED
Applications and realized dynamics stay separate
BFS applications are not treated as startups; BDS firm-age cohorts provide the realized series.
03INTERPRETATION
Support is not commercialization success
SBIR/STTR phase and amount aggregates measure public support only.
Comparisons, entities and detailed evidence — when you need them
The research workspace below retains the full analytical toolkit while keeping secondary views behind the primary visualization and findings.
Use the dominant view to locate the pattern before changing filters.
Color separates domains; size or position indicates the declared analytical measure.
Open entity or comparison views only after identifying a meaningful contrast.
Confirm evidence state, time window and limitations before interpreting a result.
Methods & provenance
NEXORA labels public observations, derived indicators, demo material, simulated outputs and interpretation separately. Missing evidence is never converted to zero or filled by hidden substitutes.

Latest source updates vary by provider. Downloads require human compliance approval.
How freshness works →Public data sources
Inspect what each official source measures, its coverage, access state, reuse boundary and current limitation.
Listing does not authorize collection or publication. Source, license, reuse scope, granularity and mosaic risk are reviewed independently; uncertainty is quarantined by default.
Public exports are held for human compliance review. Review the compliance gate →

03 / DATA CONTRACT
Data architecture
- 01
Every record keeps source, version, license, retrieval date and processing lineage
- 02
Evidence status and sensitivity status remain independent
- 03
Derived, scenario and AI outputs inherit the highest input sensitivity
- 04
Unknown source or reuse rights trigger quarantine and human review
- 05
Public modules never fill gaps with invented or unconfirmed values
