OxiGeo 0.2.0 Released — OxiGDAL Has a New Name, and 74 Crates Just Moved With It

OxiGDAL is now OxiGeo. Version 0.2.0 is a rename-only release — functionally identical to v0.1.7 — that republishes all 74 crates, the CLI, and the Python/npm/WASM/mobile bindings under the oxigeo name. Old GitHub URLs redirect; v0.1.7 remains the final OxiGDAL release. The sovereign geospatial layer for the COOLJAPAN ecosystem, now under its permanent name.

The Pure Rust GDAL alternative just got the one change that doesn’t touch a single line of logic — its own name.

Today we released OxiGeo 0.2.0 — the first release under a new project name. OxiGeo is what OxiGDAL is now called. Nothing about the code changed: 0.2.0 is functionally identical to v0.1.7, the production-hardening release published earlier today under the old name. What changed is every identifier that spelled out the old name: 74 crates on crates.io, the CLI binary, the Python and npm packages, the C/mobile FFI symbols, the WASM artifacts, and the environment variables all now say oxigeo instead of oxigdal.

No C. No C++. No Fortran. No PROJ/GEOS, no libsqlite3, no ring — the C-free default build carries over untouched, because the build itself didn’t change. OxiGeo still compiles to a single static binary (or a sub-1MB WASM bundle) and runs everywhere Rust runs: Linux, macOS, Windows, WASM, iOS, Android, and bare-metal no_std. This is an independent reimplementation and is not affiliated with the GDAL project — the rename makes that distinction a little cleaner too.

Why the rename matters

A name borrowed from the library you’re replacing creates its own friction over time:

OxiGeo 0.2.0 draws a clean line under all of that with a name that’s fully its own, while keeping every promise the old name made:

Technical Deep Dive: what actually moved

  1. Crates and Cargo identity. Every crate name changes from oxigdal/oxigdal-<name> to oxigeo/oxigeo-<name> across all 74 published crates (the workspace has 76 total; oxigeo-python and oxigeo-examples are publish = false). Rust API types that carried the old prefix — OxiGdalError and siblings — become OxiGeo* (OxiGeoError).

  2. CLI and runtime identifiers. The CLI binary is oxigeo instead of oxigdal. Every OXIGDAL_* environment variable (OXIGDAL_CONFIG, OXIGDAL_HOST, OXIGDAL_PORT, OXIGDAL_WORKERS, OXIGDAL_LOG_LEVEL, OXIGDAL_DATA_DIR, OXIGDAL_CACHE_DIR) becomes OXIGEO_*. Runtime strings follow suit: the HTTP User-Agent is now OxiGeo/1.0, the Kafka consumer group is oxigeo-etl, the ETL checkpoint directory is oxigeo-checkpoints, the edge cache directory is .oxigeo_cache, and the attestation format id is oxigeo-attestation.

  3. Language bindings. The PyPI package is now oxigeo (import oxigeo, native module oxigeo._oxigeo). The npm packages are @cooljapan/oxigeo, @cooljapan/oxigeo-node (plus its platform packages), and @cooljapan/oxigeo-geoparquet. WASM build artifacts follow the same pattern (oxigeo_wasm*, napi artifact oxigeo.<triple>.node).

  4. Native and container surfaces. C/mobile FFI symbols now carry the oxigeo_ prefix; the JNI class is com.cooljapan.oxigeo.OxiGeo; the mobile header is oxigeo_mobile.h with include guard OXIGEO_MOBILE_H. Container images move from oxigdal/* to oxigeo/*, and the systemd unit is oxigeo-server.service.

Getting Started

[dependencies]
oxigeo = "0.2"  # GeoTIFF + GeoJSON + Shapefile by default

# Full feature set:
oxigeo = { version = "0.2", features = ["full"] }

use oxigeo::Dataset;

fn main() -> oxigeo::Result<()> {
    let dataset = Dataset::open("world.tif")?;
    println!("Format : {}", dataset.format());
    println!("Size   : {}x{}", dataset.width(), dataset.height());
    println!("CRS    : {}", dataset.crs().unwrap_or("unknown"));
    Ok(())
}

Everything else — the 17 format drivers, the CRS transforms, the raster/vector algorithms, the four hosted WASM demos (GeoLab, GeoSentinel, GeoVault, GeoParquet Live) — works exactly as it did under the OxiGDAL name, because it’s the same ~747K-SLoC, 76-crate codebase underneath.

What’s New in 0.2.0

Tips

This is the foundation

OxiGeo leans on the same Pure Rust COOLJAPAN stack it did as OxiGDAL, unchanged by the rename: CRS transforms run on OxiProj, HDF5 and NetCDF read/write through oxih5 and oxinetcdf, SQLite via oxisql-sqlite-compat (Limbo), TLS via OxiTLS, compression across the format drivers via the OxiArc family (oxiarc-zstd, -lz4, -deflate, -lzw, -bzip2, -brotli, -snappy, -archive), ML tensor math via SciRS2-Core, model export and inference validated against OxiONNX, and model-weight serialization on OxiCode instead of bincode. Every one of those is itself Pure Rust — which is how a 76-crate, ~747K-SLoC workspace keeps a C-free default build with no hidden native dependency anywhere in the tree, under either name.

Star the repo if you’d rather your geospatial dependency have a name of its own than one borrowed from the library it replaced. The 76 crates, the 17 format drivers, and the C-free build are exactly as real as they were yesterday — just under the name they were always going to end up with.
