traits.build vs wooldridge: at a glance
What is traits.build?
The AusTraits engine, generalised for anyone's trait database, now links measurements to real specimens.
traits.build is the harmonisation workflow extracted from AusTraits and generalised so other groups can assemble trait databases from heterogeneous sources. Its schema and ontology reached 1.0.0 in late 2024, and the package now leans on austraits itself for the functions that belong to database consumption rather than construction. The 2025 release extends the data model with identifiers and methods tables.
What is wooldridge?
A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.
wooldridge ships the datasets from Wooldridge's Introductory Econometrics so students can load any of them with one command. The data has been essentially complete since the 7th-edition sets landed in 1.4-1; every release since has been about keeping the package on CRAN. The most recent tag exists only to re-run roxygen2 so that documentation URL fixes from the previous version actually reached the .Rd files.

The AusTraits engine, generalised for anyone's trait database, now links measurements to real specimens.
◆ Current state
traits.build is the harmonisation workflow extracted from AusTraits and generalised so other groups can assemble trait databases from heterogeneous sources. Its schema and ontology reached 1.0.0 in late 2024, and the package now leans on austraits itself for the functions that belong to database consumption rather than construction. The 2025 release extends the data model with identifiers and methods tables.
◆ Where it's heading
The project's direction is toward provenance and interoperability rather than throughput. Value types grew to carry standard error and standard deviation, the methods table now records what kind of source each dataset came from, and the identifiers table lets a trait value point at a herbarium sheet, a museum accession or a GenBank record. Alongside that, responsibilities have been split with the sibling austraits package, with shared functions moved out under deprecation shims. A published paper and a versioned ontology mark it as infrastructure meant for outside adoption, not just for AusTraits.
◆ Prediction
Expect further schema extensions in the same provenance direction, since the last two releases both added structure for describing where a measurement came from rather than new processing capability.
wooldridge
0.0INFRA · APIS
A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.
◆ Current state
wooldridge ships the datasets from Wooldridge's Introductory Econometrics so students can load any of them with one command. The data has been essentially complete since the 7th-edition sets landed in 1.4-1; every release since has been about keeping the package on CRAN. The most recent tag exists only to re-run roxygen2 so that documentation URL fixes from the previous version actually reached the .Rd files.
◆ Where it's heading
The maintainer has been systematically shrinking the package's attack surface for years. Dependencies used only for vignette examples were cut after one of them broke its API and triggered a CRAN removal notice; test infrastructure moved from testthat to tinytest and from Travis and AppVeyor to GitHub Actions; datasets were compressed by stripping attributes left over from the Stata imports. The stated goal, written into the 1.4-2 notes, is that this should be the easiest package the maintainer has to look after.
◆ Prediction
Nothing in the recent entries points to new data; the next release will most likely be triggered by another CRAN check failure or by a new edition of the textbook adding datasets.
