数据模型设计 ​

内容数据模型

javascript
// 内容主表
const contentSchema = {
  id: 'string',
  title: 'string',
  slug: 'string',
  content: 'string',
  excerpt: 'string',

  // 内容元数据
  type: 'string',           // article, video, podcast, infographic
  category: 'string',
  tags: ['string'],
  language: 'string',

  // SEO信息
  seo: {
    metaTitle: 'string',
    metaDescription: 'string',
    keywords: ['string'],
    canonicalUrl: 'string',
    ogImage: 'string'
  },

  // 发布信息
  status: 'string',         // draft, review, approved, published, archived
  publishDate: 'date',
  platforms: [{
    name: 'string',         // website, facebook, twitter, linkedin
    status: 'string',       // pending, published, failed
    publishedAt: 'date',
    postId: 'string',
    url: 'string'
  }],

  // 作者信息
  author: {
    id: 'string',
    name: 'string',
    email: 'string'
  },

  createdAt: 'date',
  updatedAt: 'date'
};

内容创作自动化 ​

热点监控和内容策划 ​

热点监控系统

javascript

AI辅助内容生成 ​

智能内容生成器
