ECHO Data Package

Every dataset on ECHO can be downloaded as an ECHO Data Package: the original files, unchanged, together with the same data converted into a small set of standard tables, documented column by column, in open formats, with machine-readable metadata, licence and credit.

Versions of the standard

The current version is 1.0.0. Every package states the version of the standard it follows in its datapackage.json (echo:edp_version).

Which formats a package contains

Which secondary formats (CSV, JSON Lines, GraphML) a table is given depends on its size. The rules are described on Formats by size.

Using a package

• Read README.md first: it describes the dataset, every table and column, and how to cite it.
• The tables in data/ are Apache Parquet files. Python, R, DuckDB, Spark and most data tools read them directly, also over HTTP without downloading the file first.
• datapackage.json (Frictionless Data Package) and croissant.json (MLCommons Croissant) describe the package for software, including the type and meaning of every column.
• original/ holds the files exactly as their creators published them.
• manifest-sha256.txt lists the SHA-256 checksum of every file, so a download can be verified.
