camtrapdp vs units: at a glance
What is camtrapdp?
camtrapdp has become a full read-edit-write toolkit for camera trap datasets, then went quiet
camtrapdp reads, filters and writes Camera Trap Data Packages in R, with export paths to Darwin Core and EML for GBIF publication. The round trip closed at 0.4.0, when write_camtrapdp() joined the existing reader; everything since has been standard-version upkeep and dependency alignment. The latest release does no user-facing work at all — it raises the R floor to 4.1.0, switches to base pipes, and pins {frictionless} >= 1.3.0.
What is units?
units reaches 1.0 by rewriting its parser and accepting the breakage that comes with it.
units attaches physical units to R vectors on top of the udunits2 library, covering arithmetic, conversion and ggplot2 scales. Version 1.0-0 replaced the unit-expression tokenizer so numbers are consistently treated as prefixes, and expressions like ml/min/1.73m^2 now parse the way physiologists write them. Printing follows NIST conventions, and 1.0-1 is a fix pass over memory handling and parser edge cases.

◆ Current state
camtrapdp reads, filters and writes Camera Trap Data Packages in R, with export paths to Darwin Core and EML for GBIF publication. The round trip closed at 0.4.0, when write_camtrapdp() joined the existing reader; everything since has been standard-version upkeep and dependency alignment. The latest release does no user-facing work at all — it raises the R floor to 4.1.0, switches to base pipes, and pins {frictionless} >= 1.3.0.
◆ Where it's heading
Development tracks two things it does not control: the Camtrap DP specification and the frictionless package underneath it. Each release so far has absorbed a spec bump (1.0.1, then 1.0.2) or an upstream API change, with the package's own surface largely settled since contributors(), individuals() and taxa() landed. The metadata-scope logic — filters rewriting spatial, temporal and taxonomic scope automatically — is the one genuinely opinionated piece and it has not been revisited.
◆ Prediction
The next release is most likely another spec-tracking one, upgrading datasets to whatever Camtrap DP version follows 1.0.2, since that has been the trigger for every release after the write path closed.
units
0.0ANALYTICS
units reaches 1.0 by rewriting its parser and accepting the breakage that comes with it.
◆ Current state
units attaches physical units to R vectors on top of the udunits2 library, covering arithmetic, conversion and ggplot2 scales. Version 1.0-0 replaced the unit-expression tokenizer so numbers are consistently treated as prefixes, and expressions like ml/min/1.73m^2 now parse the way physiologists write them. Printing follows NIST conventions, and 1.0-1 is a fix pass over memory handling and parser edge cases.
◆ Where it's heading
The long 0.8-x run was accretion — ggplot2 scales absorbed from ggforce, ud_convert(), matrix methods, steady performance work — while known parsing defects stayed in place. The 1.0 release finally traded backwards compatibility for correct parsing, and 1.0-1's pointer-wrapping and exception-propagation work suggests the C++ glue is being hardened behind it. Fixes cluster at the udunits2 boundary, which remains the main source of surprises.
◆ Prediction
Expect continued patch releases against udunits2 quirks and the new tokenizer's fallout rather than new surface area, with the ggplot2 integration and conversion helpers already in place.
