What is nanoparquet?

nanoparquet is chasing byte-level agreement with the Java and Rust Parquet readers, not feature count.

nanoparquet reads and writes Parquet from R with no Arrow dependency, which is its entire reason to exist. The 0.4.0 line renamed the reader API and added schema authoring plus `append_parquet()`, and the 0.5.x releases have gone after interoperability: definition and repetition level encodings the Apache Parquet Java library expects, flatbuffer alignment the Rust arrow-rs reader expects, 128-bit decimals, and Polars-written files that omit the dictionary page offset. The newest release adds `bit64::integer64` columns and writing to stdout.

What is ReLTER?

An interface to Europe's long-term ecosystem research network that went quiet after 2.0.

ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.

nanoparquet is chasing byte-level agreement with the Java and Rust Parquet readers, not feature count.

◆ Current state

nanoparquet reads and writes Parquet from R with no Arrow dependency, which is its entire reason to exist. The 0.4.0 line renamed the reader API and added schema authoring plus `append_parquet()`, and the 0.5.x releases have gone after interoperability: definition and repetition level encodings the Apache Parquet Java library expects, flatbuffer alignment the Rust arrow-rs reader expects, 128-bit decimals, and Polars-written files that omit the dictionary page offset. The newest release adds `bit64::integer64` columns and writing to stdout.

◆ Where it's heading

Almost every entry since 0.4.0 names another engine — Java, arrow-rs, Polars, Arrow schema metadata — which tells you the maintainers are treating cross-reader fidelity as the product rather than R-side ergonomics. The type system is filling in from the edges: DECIMAL beyond 8 bytes, UUID, FLOAT16 and INTERVAL as raw lists, and now 64-bit integers with an explicit read-type option instead of a silent cast to double. Writing to `:stdout:` points at a second audience, shell pipelines rather than interactive R.

◆ Prediction

The remaining unmapped Parquet types the changelog has been parking in raw-vector lists — FLOAT16 and INTERVAL — are the obvious next targets, following the same pattern by which DECIMAL and UUID graduated to real R types.

An interface to Europe's long-term ecosystem research network that went quiet after 2.0.

◆ Current state

ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.

◆ Where it's heading

The visible arc runs from a scattered set of getSite* functions to a reviewed, documented package, and then stops. The absence of notes on the 2.0.0 tag makes it impossible to say from this feed what that major version changed, and the three-year silence afterwards is the more informative signal. What the package does remains useful — the eLTER data it wraps has no other R interface — but the release history gives no evidence of active development.

◆ Prediction

Nothing in these entries supports a confident prediction about future releases; the feed shows a major version with no notes followed by silence. Whether the package is dormant or simply publishing releases elsewhere cannot be determined from what is here.
