L1centrality vs traits.build: at a glance
What is L1centrality?
A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.
L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.
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.

L1centrality
0.0INFRA · APIS
A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.
◆ Current state
L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.
◆ Where it's heading
The package has moved from defining measures to operationalizing them. 0.5.0 was the inflection: parallel local computation and list-valued group input both target users running these measures over many vertex sets or large graphs rather than illustrating them on one. The same release renamed weight_transform and eta to edge_weight_transform and vertex_weight, and added an explicit message when a distance matrix is received — the signature of a maintainer fielding the same misuse repeatedly.
◆ Prediction
The last two releases carry no functional change, so the near-term path is maintenance rather than new measures; a 0.6.0 would most likely extend parallelism beyond L1centLOC to the other computationally heavy variants.
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.
