dwctaxon vs rbmi: at a glance
What is dwctaxon?
A Darwin Core validator that went quiet for two years, then surfaced only to raise its R floor
dwctaxon edits and validates taxonomic data held in Darwin Core format, enforcing the referential rules that make a taxonomic database internally consistent. Its last real functional change was 2.0.3 in December 2023, which loosened an over-strict uniqueness requirement in column matching. The most recent entry is a development build two years later that does nothing but set a minimum R version and bump Roxygen.
What is rbmi?
Reference-based multiple imputation for trials, now shipping without Bayesian support by default.
rbmi implements reference-based multiple imputation for longitudinal clinical trial data with missing values — the estimand machinery regulators expect for handling intercurrent events and dropout. The consequential recent change was 1.3.0 moving rstan from a hard dependency to Suggests, which takes Bayesian imputation out of the default install. Since then the work has been documentation and nomenclature discipline: 1.6.1 standardized on MNAR over a mixed NMAR/MNAR vocabulary and deprecated the nmar.rm argument accordingly.

◆ Current state
dwctaxon edits and validates taxonomic data held in Darwin Core format, enforcing the referential rules that make a taxonomic database internally consistent. Its last real functional change was 2.0.3 in December 2023, which loosened an over-strict uniqueness requirement in column matching. The most recent entry is a development build two years later that does nothing but set a minimum R version and bump Roxygen.
◆ Where it's heading
The visible arc is a package converging on correctness rather than growing. The 2.0.3 change is the most consequential: matching a reference column no longer demands that every value in it be unique, only that the matched values be — which is what makes dct_fill_col() usable on real taxonomic tables where scientificName legitimately repeats. Around it sits compliance work: an internet-connection and URL check added purely to satisfy CRAN policy, and examples reworked to restore user settings and skip deliberate errors.
◆ Prediction
The 2.0.3.9001 development stamp with an R >= 4.2.0 requirement suggests a 2.0.4 release is being prepared, most likely as maintenance rather than new validation rules. The two-year gap makes any stronger claim unsupported by the feed.

2.5ANALYTICS
Reference-based multiple imputation for trials, now shipping without Bayesian support by default.
◆ Current state
rbmi implements reference-based multiple imputation for longitudinal clinical trial data with missing values — the estimand machinery regulators expect for handling intercurrent events and dropout. The consequential recent change was 1.3.0 moving rstan from a hard dependency to Suggests, which takes Bayesian imputation out of the default install. Since then the work has been documentation and nomenclature discipline: 1.6.1 standardized on MNAR over a mixed NMAR/MNAR vocabulary and deprecated the nmar.rm argument accordingly.
◆ Where it's heading
The package is optimizing for adoption friction over feature breadth. Dropping a compiled Stan dependency from the default install, deprecating a bespoke seed argument in favor of base set.seed(), and aligning lsmeans() behavior and weight naming with emmeans all point the same direction — behave like a conventional R package rather than a specialized one. Documentation work in 1.6.1 covering @return on every exported function and executable examples reads as preparation for validation scrutiny rather than user demand.
◆ Prediction
Given the FAQ vignette's validation statement and the recent documentation completeness pass, the next work is more likely qualification and estimand documentation than new imputation methods.
