This document provides comprehensive guidelines for using and designing schema.org structured data, covering naming conventions, data modeling principles, and best practices for technical implementation. (本文档提供了使用和设计 schema.org 结构化数据的全面指南，涵盖命名规范、数据建模原则和技术实施最佳实践。)

Schema.org employs a flexible, RDF Schema-derived data model with multiple inheritance types and properties, designed pragmatically for search engine optimization rather than as a universal ontology. It emphasizes extensibility and conformance flexibility, supporting formats like JSON-LD and Microdata. (Schema.org采用基于RDF Schema的灵活数据模型，支持多重继承的类型和属性，旨在优化搜索引擎而非构建通用本体。它强调可扩展性和合规灵活性，支持JSON-LD和Microdata等格式。)

Schema.org is defined as two hierarchies: one for textual property values, and one for the things that they describe. This document presents the main type hierarchy, a collection of types (or "classes") each with one or more parent types, shown in a tree structure. (Schema.org 被定义为两个层次结构：一个用于文本属性值，另一个用于它们所描述的事物。本文档展示了主要的类型层次结构，这是一个类型（或“类”）的集合，每个类型都有一个或多个父类型，并以树状结构呈现。)

Schema.org provides a hierarchical vocabulary of 827 types and 1528 properties for structured data markup, with community extensions and development processes. (Schema.org提供包含827种类型和1528个属性的层次化词汇表，用于结构化数据标记，支持社区扩展和开发流程。)

Schema.org is a collaborative initiative by major search engines to create a unified structured data markup vocabulary, improving web content understanding and enabling richer search results. (Schema.org 是由主要搜索引擎共同发起的协作项目，旨在创建统一的结构化数据标记词汇表，以增强网页内容理解并实现更丰富的搜索结果。)

This guide introduces schema.org and Microdata for adding structured data to web pages, helping search engines better understand content. It covers basic concepts like itemscope, itemtype, and itemprop, along with practical examples and advanced topics like dates and enumerations. (本指南介绍如何使用 schema.org 和微数据为网页添加结构化数据，帮助搜索引擎更好地理解内容。涵盖 itemscope、itemtype 和 itemprop 等基本概念，并提供实际示例及日期、枚举等高级主题。)

This document outlines Schema.org's structured process for vocabulary development, including community collaboration, release cycles, and extension mechanisms. (本文概述了Schema.org词汇表开发的结构化流程，包括社区协作、发布周期和扩展机制。)
