Module: Validation/LanguageMetadata

INTELLIGENCE OPERATIVE PERSPECTIVE

This validator ensures the homepage and main content pages maintain proper language metadata across all 14 supported language editions. While appearing as a technical SEO task, language validation serves critical intelligence functions: ensuring international readers can discover content in their language, preventing search engine deindexing, and maintaining consistent information architecture across the multilingual platform.

METADATA VALIDATION FRAMEWORK: The validator checks seven critical metadata elements for each language:

  1. HTML lang Attribute Correctness

    • Validates lang="xx" matches ISO 639-1 language codes
    • Detects mismatches (e.g., Swedish content with lang="en")
    • Critical for: Screen readers, search engines, browser font selection Intelligence impact: Accessibility for visually-impaired international readers

  2. dir="rtl" for Right-to-Left Languages

    • Validates Arabic (AR) and Hebrew (HE) have dir="rtl" attribute
    • Detects LTR incorrectly applied to RTL content
    • Critical for: Text layout, number display, punctuation handling Intelligence impact: Readability for Middle Eastern audience

  3. Title Tag Presence & Uniqueness
