ZIPpakattu

ZIPpakattu is a packaging concept that combines ZIP compression with a standardized manifest to describe the contents, provenance, and integrity of a data bundle. It is intended for distributing software, datasets, and media where automated validation and metadata are valuable.

The name blends ZIP, the common compression format, with pakattu, a term meaning packed in several languages, signaling a tightly bundled package. The concept emerged in open‑source and data‑sharing communities in the early 2020s as a lightweight alternative to more complex container formats.

A ZIPpakattu archive typically contains a root manifest file, such as manifest.json or manifest.xml, plus a metadata directory that describes files, checksums, creators, licenses, and timestamps. Optional sections may include a dependencies manifest, a data/ directory, and a readme. Validation relies on per‑file checksums and a root hash to ensure integrity, while path and permission metadata support controlled extraction.

Usage and considerations: It is used for distributing datasets, software releases, and media collections where quick extraction and integrity verification are important. Advantages include broad cross‑platform compatibility, ease of streaming or partial extraction, and straightforward validation. Limitations include dependence on ZIP tooling and potential metadata overhead that increases archive size, as well as security considerations with embedded executables or scripts if not properly sandboxed and validated.
