rredlist vs taxa
A side-by-side editorial comparison of rredlist and taxa — release velocity, themes, recent moves, and the top alternatives to consider.
rredlist vs taxa: at a glance
What is rredlist?
rredlist threw out its species-centric API in 1.0.0 and rebuilt around assessments.
rredlist 1.0.0 is a hard break: the IUCN Red List API moved to v4, and the package followed by dropping v3 support entirely, reorganising around assessments rather than species, renaming or removing most functions, changing returned data structures, and requiring users to generate a new API key. The two releases since are consolidation on that new shape — `rl_assessment_list()` and `rl_assessment_extract()` for retrieving and unpacking many assessments at once, a `scope` argument on the `*_latest()` functions, and NULL-safe extraction.
What is taxa?
taxa started a ground-up rewrite in 2021 and has published almost nothing since.
0.4.0 began a complete rewrite aimed at making the component classes behave like base R vectors, explicitly shipping without the `taxmap` class and parking the old implementation inside metacoder until the new one matured. Four years later that is still where things stand: 0.4.2 experimented with `''` instead of `NA` for missing values and chased a vctrs test break, and 0.4.4 fixed CRAN check issues. The releases before the rewrite were the productive ones — `taxonomy_table()`, `print_tree()`, `get_dataset()`, fuzzy name matching, faster parsers.

0.0ANALYTICS
rredlist threw out its species-centric API in 1.0.0 and rebuilt around assessments.
◆ Current state
rredlist 1.0.0 is a hard break: the IUCN Red List API moved to v4, and the package followed by dropping v3 support entirely, reorganising around assessments rather than species, renaming or removing most functions, changing returned data structures, and requiring users to generate a new API key. The two releases since are consolidation on that new shape — `rl_assessment_list()` and `rl_assessment_extract()` for retrieving and unpacking many assessments at once, a `scope` argument on the `*_latest()` functions, and NULL-safe extraction.
◆ Where it's heading
Post-1.0.0 work is clearly aimed at bulk use: fetch many assessments, pull a chosen field out of each. That is a different usage pattern from the one-species-at-a-time queries the v3-era functions encouraged, and it suits the conservation-analysis workloads the package is actually used for. Deprecated v3 functions are still present and flagged for eventual removal.
◆ Prediction
The deprecated v3-era functions are the obvious next thing to disappear, and further bulk-retrieval helpers are likely given both post-1.0 releases went that way.
taxa
0.0ANALYTICS
taxa started a ground-up rewrite in 2021 and has published almost nothing since.
◆ Current state
0.4.0 began a complete rewrite aimed at making the component classes behave like base R vectors, explicitly shipping without the `taxmap` class and parking the old implementation inside metacoder until the new one matured. Four years later that is still where things stand: 0.4.2 experimented with `''` instead of `NA` for missing values and chased a vctrs test break, and 0.4.4 fixed CRAN check issues. The releases before the rewrite were the productive ones — `taxonomy_table()`, `print_tree()`, `get_dataset()`, fuzzy name matching, faster parsers.
◆ Where it's heading
The rewrite has not landed. `taxmap`, the class most users came for, was never reimplemented in the new design, and the only releases since are CRAN compliance. Meanwhile metacoder still carries the old taxa, which means the ecosystem is running on the version the rewrite was meant to replace. This reads as a stalled migration rather than an active one.
◆ Prediction
Nothing in the entries indicates the rewrite is resuming; the likely next release is another CRAN-check fix. Whether `taxmap` ever arrives in the new design is unresolved.
