iiasa / ixmp4

A data warehouse for high-powered scenario analysis in the domain of integrated assessment of climate change and energy systems modeling

PythonMIT★ 14 stars⑂ 8 forkssince Apr 2023View on GitHub ↗

iiasa/ixmp4 holds a health index of 70 out of 100, placing it in the Good band. It scores highest on Engineering Quality (91/100) and lowest on Community & Adoption (49/100). It was last updated 27 days ago. A single contributor accounts for most of its recent work.

Software health index

Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At risk ceiling of 49. AI Readiness sits outside the overall score.

70
Excellent85-100Exemplary; meets essentially all checked criteria

Score profile

Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.

When each star and fork was added, collected from GitHub and bucketed by day. Cumulative growth sits directly above the daily additions it is made of, so the two read against each other: steady organic accretion looks nothing like an abrupt, short-lived burst. Where that difference is measurable, it is reported as growth authenticity.

Dependency advisories 0

Installing pypi:ixmp4@0.16.6 pulls in 69 packages, direct and transitive: 0 carry known advisories, of which 0 are direct dependencies.

No known advisories affect the assessed dependencies.

An advisory means the version recorded in the dependency graph falls inside an advisory’s affected range. Reachability is not analysed, and the graph includes development and test pins — a finding may concern tooling rather than shipped software.
