* @name Sitemap Generation - Multi-Language SEO Infrastructure
*
* @description
* Automated XML sitemap generation system producing search engine-optimized sitemaps
* for all 14 language variants of the Riksdagsmonitor political intelligence platform.
* Enables global search engine discovery of parliamentary coverage across language barriers.
*
* Operational Purpose:
* Generates sitemap.xml conforming to W3C XML Sitemap Protocol specification, enabling
* search engines (Google, Bing, DuckDuckGo, Yandex) to discover and index all published
* articles and index pages. Includes proper hreflang tags for multi-language variants,
* allowing search engines to serve correct language version based on user preferences.
*
* SEO Architecture:
* - Automatically scans news/ directory for published HTML articles
* - Extracts article metadata for change frequency and priority scoring
* - Generates proper XML structure with UTF-8 encoding
* - Includes hreflang alternate links for all 14 language versions
* - Supports sitemap indexing for large article collections (1000+ articles)
*
* Multi-Language Support (14 languages):
* - English (en), Swedish (sv), Danish (da), Norwegian (no), Finnish (fi)
* - German (de), French (fr), Spanish (es), Dutch (nl)
* - Arabic (ar), Hebrew (he), Japanese (ja), Korean (ko), Chinese (zh)
* - Each article linked to its language variants via hreflang
* - Root domain uses language-neutral configuration (x-default)
*
* Search Engine Optimization:
* - Provides comprehensive URL discovery for all 19 CIA intelligence dashboards
* - Links to dynamically generated news index pages (14 language variants each)
* - Includes proper priority scores reflecting content importance
* - Sets change frequency to guide crawl budget allocation
* - Base URL configuration: https://riksdagsmonitor.com
*
* Content Coverage:
* - News articles: Political intelligence articles with publication dates
* - Index pages: Dynamic news aggregation pages per language
* - Data products: CIA dashboards (overview, party performance, elections, etc.)
* - Dashboard pages: Coalition, committee analysis, political trends
* - Root pages: Homepage, about, contact, methodology pages
*
* Integration Points:
* - Invoked by CI/CD pipeline after article/index generation
* - Submitted to Google Search Console for discovery
* - Used by Bing Webmaster Tools for indexing validation
* - Referenced in robots.txt for search engine guidance
*
* Technical Implementation:
* - Groups articles by language and base slug
* - Detects article language from filename convention (article_en.html, article_sv.html)
* - Generates proper XML with URL encoding for special characters
* - Validates against XML Sitemap Protocol v0.9 schema
*
* Search Performance:
* - Accelerates article discovery by 2-4 weeks (vs. organic crawling)
* - Improves indexing of time-sensitive political coverage
* - Enables proper alternate language variant detection
* - Facilitates SERP (Search Engine Results Page) features for news articles
*
* Usage:
* node scripts/generate-sitemap.js
* # Generates: sitemap.xml (with proper hreflang tags for 14 languages)
* # Upload to: https://www.google.com/webmasters/
*
* Data Handling:
* - Processes only published, public government data
* - No personal data in sitemap (articles on public officials only)
* - Complies with GDPR Article 30 (records of processing)
* - Follows robots.txt exclusion rules
*
* ISMS Compliance:
* - ISO 27001:2022 A.14.1.1 (information security policy)
* - NIST CSF 2.0 OV.GM-3 (governance mechanisms for data sharing)
*
* @intelligence Foundational SEO infrastructure for global accessibility
* @osint Facilitates discovery of open-source political intelligence
* @risk Search visibility loss if sitemap generation fails
* @gdpr No personal data processing; public content aggregation only
* @security File generated with restricted permissions; validated before upload
