It includes a RESTful API and a self-hosted web interface, allowing users to manage their collection via a browser or programmatic requests. Capabilities include automatic metadata fetching to populate page

Ibis is a portable Python dataframe library and multi-backend query engine that provides a unified interface for executing data transformations across diverse compute engines. It functions as a Python SQL expression compiler and dialect transpiler, allowing users to define data logic once and execute it across cloud warehouses, embedded databases, and distributed clusters without rewriting code. The project distinguishes itself through a database backend abstraction that decouples transformation logic from the underlying execution engine. It enables polyglot data workflows by mixing raw SQL s

yii2_fecshop ist eine umfassende B2C-E-Commerce-Plattform und ein CMS, das auf dem Yii2-PHP-Framework basiert. Es fungiert als Headless-Commerce-API und internationale Storefront-Lösung und unterstützt sowohl Single-Vendor-Shops als auch Multi-Vendor-Marktplätze, auf denen unabhängige Händler ihre eigenen Produkte und Bestellungen verwalten können. Das System zeichnet sich durch eine Multi-Entry-Point-Architektur aus, die administrative, Web-, Mobile- und API-Interfaces trennt, während sie sich eine gemeinsame Service-Ebene teilen. Es bietet hohe Erweiterbarkeit durch konfigurationsgesteuerten Service-Austausch, ereignisgesteuerte funktionale Erweiterungen und ein priorisiertes Template-System für visuelle Anpassungen.
