eratosthenes vs nominatimlite: at a glance
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
What is nominatimlite?
nominatimlite's real work was self-hosting and caching; 0.6.0 is an internal refactor with no API change
nominatimlite is a dependency-light R client for the Nominatim geocoding API, returning results as plain data frames or sf objects. The features that define it landed in 0.4.0 — structured queries, local Nominatim server support, and JSONV2 output — and 0.5.0 added session-scoped caching plus a 1.2-second inter-request delay to stay within the public API's usage policy. 0.6.0 in June 2026 changed no public behaviour.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

nominatimlite's real work was self-hosting and caching; 0.6.0 is an internal refactor with no API change
◆ Current state
nominatimlite is a dependency-light R client for the Nominatim geocoding API, returning results as plain data frames or sf objects. The features that define it landed in 0.4.0 — structured queries, local Nominatim server support, and JSONV2 output — and 0.5.0 added session-scoped caching plus a 1.2-second inter-request delay to stay within the public API's usage policy. 0.6.0 in June 2026 changed no public behaviour.
◆ Where it's heading
The package has settled. Recent effort goes to being a well-behaved API citizen and to internal consistency: 0.6.0 raised the minimum R to 4.1.0 and refactored URL construction, progress handling, coordinate validation and output preparation with AI assistance, explicitly leaving the public API untouched. That refactor is part of a sweep across the same maintainer's packages in the same weeks.
◆ Prediction
With the API surface stable and rate-limiting handled, future releases most likely track upstream Nominatim endpoint changes, as 0.4.0 did for v4.4.0. Nothing in the entries points to new query capabilities.
