# Systems-analysis.info

> Multilingual reference and knowledge website with two complementary content layers: a static public HTML site of curated articles, literature, publications, and source materials; and Russian, English, and international MediaWiki knowledge bases. Core subjects include systems theory, systems analysis, operations research, decision theory, modeling, management, systems engineering, methodology, mathematics, data science, artificial intelligence, and large language models.

This file is a detailed routing layer for language models and agents. Select the user's language first, then select the content layer and the subject. Use the static public site for authored overviews, classical methodologies, literature pages, publications, and stable thematic reading paths. Use the wiki branches for encyclopedic expansion, section catalogs, semantic networks, literature indexes, categories, terminology, and multilingual discovery.

Russian content uses the public root and `/wiki/`; English content uses `/` and `/eng/`; Spanish combines `/es/` with the Spanish master catalog in `/int/`; Japanese combines `/ja/` with the Japanese master catalog in `/int/`; other languages primarily use `/int/`, language categories, and language-specific sitemap routes. Russian, English, and Spanish have developed static article trees. The Japanese static branch is under construction: it already provides the full set of navigation pages and a growing number of articles, so prefer a `/ja/` page when it exists and fall back to `/int/` otherwise. Several other languages have compact public landing pages, but a language listed in the global sitemap must not be assumed to have a complete static article tree.

Choose the routing structure by task: use a section catalog for a curated subject overview; a semantic network for concept relationships; a literature page for sources and further reading; a category for broad discovery of all classified pages; a local static map for the authored article hierarchy; a language sitemap for language-specific routing; and XML sitemaps only for exhaustive crawling. AI and LLM content is one peer subject branch within the wider systems-analysis architecture and must not be treated as the default route for unrelated requests.

For downloadable full-text books and source collections, use the dedicated Russian static catalogs at `/ru/systems_analysis_book.html` and `/ru/operation_research_book.html`; these pages group book files by subject and supplement them with related literature, annuals, network-planning materials, articles, and presentations. For language-wide discovery in the international wiki, use direct MediaWiki category routes in the literal form `/int/Category:<English_language_name>`, for example `/int/Category:Spanish`. The top-level `/int/Category:Language` route enumerates the individual language categories. A language category is a broad classification index and may contain more, fewer, or less curated pages than the corresponding master language catalog.

To determine the current number of pages available in a language, consult the corresponding language category or the relevant XML sitemap. A MediaWiki language category reports its current total membership above the paginated list even when only the first 200 entries are displayed. For machine-readable enumeration, count the page URL records in the applicable XML sitemap: use `/wiki/sitemap.xml` for the Russian wiki, `/eng/sitemap.xml` for the English wiki, and `/int/sitemap.xml` for the international multilingual branch. For one language inside `/int/`, prefer `/int/Category:<English_language_name>` as the direct per-language count because `/int/sitemap.xml` inventories the entire international branch. Do not assume that a language-category total and an XML-sitemap total are identical: a category counts pages explicitly assigned to that language, whereas an XML sitemap follows its own indexing and inclusion rules.

## Markdown versions of wiki articles

Markdown versions of article pages are available for all three MediaWiki branches through dedicated `/md/` mirror directories. These Markdown files are separate resources; the static public HTML site outside the three wiki branches does not use this mapping.

For a wiki article URL, preserve the article name, prepend `/md` to the wiki branch, and append `.md` to the article name:

- Russian wiki: `/wiki/<Article>` → `/md/wiki/<Article>.md`
- English wiki: `/eng/<Article>` → `/md/eng/<Article>.md`
- International multilingual wiki: `/int/<Article>` → `/md/int/<Article>.md`

Example:

- `https://systems-analysis.info/wiki/Системный_анализ` → `https://systems-analysis.info/md/wiki/Системный_анализ.md`

For machine-readable enumeration of the Markdown article files, use the dedicated XML sitemaps:

- [Russian wiki Markdown sitemap](https://systems-analysis.info/md/wiki/sitemap.xml)
- [English wiki Markdown sitemap](https://systems-analysis.info/md/eng/sitemap.xml)
- [International wiki Markdown sitemap](https://systems-analysis.info/md/int/sitemap.xml)

For machine reading of wiki articles, prefer the corresponding Markdown file. Use the XML sitemap for the relevant Markdown mirror when exhaustive discovery or availability checking is required. The `.md` sitemap files listed elsewhere in this document, including the global, language-specific, and deep-branch files under `/sitemap/`, are navigation maps and are distinct from these Markdown article files.

General HTTP Markdown content negotiation is not enabled. Sending `Accept: text/markdown` to an arbitrary HTML or MediaWiki URL does not imply that a Markdown representation will be returned.
