## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a

Fess 基于 [OpenSearch](https://github.com/opensearch-project/OpenSearch)，但不需要 OpenSearch 的知识或经验。Fess 提供了一个易于使用的管理 GUI，您可以通过浏览器配置系统。Fess 还包含一个爬虫，能够抓取 [Web 服务器](https://fess.codelibs.org/14.17/admin/webconfig-guide.html)、[文件系统](https://fess.codelibs.org/14.17/admin/fileconfig-guide.html)或[数据存储](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html)（如 CSV 或数据库）中的文档。Fess 支持多种文件格式，包括但不限于：Microsoft Office、PDF 和 zip。

Fessは[OpenSearch](https://github.com/opensearch-project/OpenSearch)をベースにしていますが、OpenSearchに関する知識や経験は**不要**です。Fessは、ブラウザを介してシステムを簡単に設定できる管理者向けのGUIを提供しています。Fessにはクローラも含まれており、[Webサーバー](https://fess.codelibs.org/14.17/admin/webconfig-guide.html)、[ファイルシステム](https://fess.codelibs.org/14.17/admin/fileconfig-guide.html)、または[データストア](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html)（CSVやデータベースなど）のドキュメントをクロールできます。Microsoft Office、PDF、zipなど、多くのファイル形式に対応しています。
