What is CHNOSZ?

A geochemistry thermodynamics engine that changed its units and its database schema in one release.

CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.

What is dscore?

The D-score reference implementation rebuilt its measurement foundation on seven countries.

dscore computes the D-score and DAZ, the GSED developmental measurement used in child-health research, and it is the reference implementation rather than one option among several. The package is at 2.1.0 after a dense 2025: the default key moved from three-country to seven-country validation data, the licence moved from AGPL to Apache 2.0, and the 2.1.0 line added per-country references, full BSID-III coverage and domain-level scoring. Breaking changes are routine here and always come with a documented fallback key or algorithm argument.

0.0

A geochemistry thermodynamics engine that changed its units and its database schema in one release.

◆ Current state

CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.

◆ Where it's heading

2.0.0 was the structural break — Joules replacing calories as the default output of subcrt(), a required E_units column, a new model column, and the removal of a legacy scaling convention for heat-capacity coefficients. Everything since has built on that settled foundation rather than disturbing it. The direction of the last two releases is toward coverage of specific mineral systems, rare earths and uranyl among them, and toward making the package approachable, which suggests a maintainer courting new users rather than reworking the engine.

◆ Prediction

The next release most likely continues OBIGT curation for particular element systems plus vignette work; the highlights format gives no signal of engine-level changes pending.

0.0

The D-score reference implementation rebuilt its measurement foundation on seven countries.

◆ Current state

dscore computes the D-score and DAZ, the GSED developmental measurement used in child-health research, and it is the reference implementation rather than one option among several. The package is at 2.1.0 after a dense 2025: the default key moved from three-country to seven-country validation data, the licence moved from AGPL to Apache 2.0, and the 2.1.0 line added per-country references, full BSID-III coverage and domain-level scoring. Breaking changes are routine here and always come with a documented fallback key or algorithm argument.

◆ Where it's heading

The arc runs from correcting the instrument to broadening who can use it. The 2020-2024 releases were item-table repair and error correction, including a scale-factor bug that altered published standard errors; from 1.11.0 onward the work is distribution — a permissive licence, more instruments mapped in, and references resolved per country rather than pooled. That combination points at national-survey and app-embedded use rather than research-only use.

◆ Prediction

The 2.0.0 notes state that groundwork was laid for extending D-scores to older children, and 2.0.0 still tells users to fall back to gsed2406 for instruments outside GSED SF and LF. Expect the next releases to close that gap by mapping more instruments into gsed2510, with the older-age extension the likeliest headline feature.

Frequently asked questions

What is the difference between CHNOSZ and dscore?

Both compete on the same themes — r-package — within Infra & APIs. CHNOSZ and dscore are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is CHNOSZ better than dscore?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. CHNOSZ and dscore are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
