Its importance comes from the BagIt format more than from the code itself: BagIt is a simple directory layout for reliable transfer and preservation of arbitrary digital content. ### プロジェクトの歴史 The BagIt format was developed in the digital-preservation community and standardized as RFC 8493 in October 2018 by contributors from the California Digital Library, Stanford Libraries, the Library of Congress, and others. The RFC describes BagIt as a filesystem hierarchy with payload files, tag files, manifests, and checksum validation rather than as a compressed archive format. The bagit-python repository was created under the Library of Congress GitHub organization in 2013. Its README presents the package as both a Python module and a `bagit.py` command-line program for turning directories into bags, updating bag metadata, regenerating manifests, and validating bags. ### 採用の歴史 RFC 8493 notes BagIt use across preservation organizations including the Library of Congress, Dryad Data Repository, NSF DataONE, the Rockefeller Archive Center, and university libraries including Cornell, Purdue, Stanford, Ghent University, New York University, and the University of California. In package-manager culture, `bagit` is a small but durable archival utility: Homebrew packages it as a formula, and the formula API reported stable version 1.9.0 with 19 installs in the previous 30 days as of June 30, 2026. ### 使われ方 Common CLI workflows are `bagit.py /path/to/dir` to create a bag, `bagit.py --validate /path/to/bag` to validate manifests and payloads, and checksum flags such as `--sha256` or `--sha512` to control manifest generation. The module API exposes the same ideas through `bagit.make_bag`, `bagit.Bag`, `save`, and `validate`. ### パッケージ好きにとっての重要性 bagit is a package nerd's preservation tool: it turns a normal directory tree into a self-describing, checksum-verifiable transfer object without forcing data into tar or zip. It is the kind of small CLI that matters in archives, data repositories, and reproducible handoffs precisely because its format is boring and inspectable with ordinary filesystem tools. ### タイムライン - 2013: LibraryOfCongress/bagit-python repository created on GitHub. - 2018: BagIt File Packaging Format v1.0 published as RFC 8493. - 2026: Homebrew formula reports stable bagit 1.9.0. ### Related projects - RFC 8493 lists implementations in several languages, including Python, Ruby, Java, Perl, and PHP. - The broader BagIt ecosystem includes archival repositories and preservation workflows that exchange bags between institutions. ### ソース - - - - ## セキュリティノート library-like package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - library-like package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** bagit - **Version Scheme:** 1 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 関連リンク - [Source-control packages](https://www.automicvault.com/ja/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/ja/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Language runtime packages](https://www.automicvault.com/ja/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [python@3.14](https://www.automicvault.com/ja/pkg/brew/python-3-14/) - Runtime dependency declared by Homebrew. - [csvkit](https://www.automicvault.com/ja/pkg/brew/csvkit/) - Shares av.db curated category or tags: cli, data, python. - [fred](https://www.automicvault.com/ja/pkg/brew/fred/) - Shares av.db curated category or tags: cli, data, python. - [glom](https://www.automicvault.com/ja/pkg/brew/glom/) - Shares av.db curated category or tags: cli, data, python. - [iredis](https://www.automicvault.com/ja/pkg/brew/iredis/) - Shares av.db curated category or tags: cli, data, python. - [kaskade](https://www.automicvault.com/ja/pkg/brew/kaskade/) - Shares av.db curated category or tags: cli, data, python. - [mysql-to-sqlite3](https://www.automicvault.com/ja/pkg/brew/mysql-to-sqlite3/) - Shares av.db curated category or tags: cli, data, python. - [overturemaps](https://www.automicvault.com/ja/pkg/brew/overturemaps/) - Shares av.db curated category or tags: cli, data, python. - [rgf](https://www.automicvault.com/ja/pkg/brew/rgf/) - Shares av.db curated category or tags: cli, data, python. - [datalad](https://www.automicvault.com/ja/pkg/brew/datalad/) - Both packages touch the same language runtime or ecosystem.
