dwctaxon vs spiro: 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 spiro?
Cardiopulmonary exercise test data in R, one metabolic cart vendor at a time.
spiro imports and processes cardiopulmonary exercise testing data in R, handling the file formats that metabolic carts from Cosmed, Cortex, Vyntus, and ZAN emit, then interpolating, smoothing, and summarizing them into comparable variables. The bulk of ongoing work is vendor format compatibility rather than analysis features — 0.2.4 fixed Cosmed imports failing in rare cases and Cortex imports on newer devices, and 0.2.2 added English-language Vyntus files after 0.1.2 added French ones. The analysis side, spiro_max(), spiro_smooth() and spiro_plot(), has been stable for some time.

◆ 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.

Cardiopulmonary exercise test data in R, one metabolic cart vendor at a time.
◆ Current state
spiro imports and processes cardiopulmonary exercise testing data in R, handling the file formats that metabolic carts from Cosmed, Cortex, Vyntus, and ZAN emit, then interpolating, smoothing, and summarizing them into comparable variables. The bulk of ongoing work is vendor format compatibility rather than analysis features — 0.2.4 fixed Cosmed imports failing in rare cases and Cortex imports on newer devices, and 0.2.2 added English-language Vyntus files after 0.1.2 added French ones. The analysis side, spiro_max(), spiro_smooth() and spiro_plot(), has been stable for some time.
◆ Where it's heading
This is a mature rOpenSci package whose remaining work is dictated by other people's file formats. Each device firmware revision, each regional language variant, and each ggplot2 release generates maintenance, and that is what fills the changelog. The API itself settled early, with the 0.1.0 rOpenSci review pass renaming the protocol helpers to the pt_* prefix and 0.2.0 replacing the confusingly named spiro_import() with spiro_raw().
◆ Prediction
Expect the pattern to continue: import fixes as vendor formats shift and periodic plotting updates tracking ggplot2, with no indication of new analysis capability.
