asar vs traits.build: at a glance
What is asar?
A NOAA report-template generator being debugged by the workshops that teach it.
asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.
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.

◆ Current state
asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.
◆ Where it's heading
The releases are paced by training events rather than a roadmap. The 2.0.0 rerender bugs — blank author sections, parameters not propagating into both the YAML and the params chunk, custom sections mislabelled — are the kind found by people actually filling in a template, and the follow-up hotfix names a workshop explicitly as where the problems surfaced. Moving the guidelines into versioned site articles, revised after workshop feedback, continues that: the standard is being treated as part of the software rather than a document beside it.
◆ Prediction
With a workshop series named as upcoming in the entries, the next release is most likely another round of template fixes reported from a live session rather than new report types.
traits.build
0.0INFRA · APIS
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.
