# HVCE Showcase — Chrisyst Datasets

> https://datasets.chrisyst.com is the live production showcase for HVCE (High-Velocity Content Engine): a programmatic SSR/SSG framework that turns structured JSONL catalogs into crawlable, AI-legible directory sites with native SEO, GEO, and AEO optimization out of the box.

This deployment demonstrates how HVCE ships production-grade discovery surfaces without a database, ORM, or client rendering framework — schema.org graphs, clean canonical routes, semantic manifests, and Markdown twins are first-class outputs of the compile and serve pipeline.

## Platform Capabilities

- [Dynamic Hybrid SSR / SSG](https://datasets.chrisyst.com/): Live Express SSR for faceted browse and entity profiles, plus a static export path that compiles the same templates into durable HTML for edge or object hosting.
- [Sub-2ms Client Faceting](https://datasets.chrisyst.com/unesco/): Zero-CLS DOM filtering with stateful URL query preservation — category, geography, and quantitative dual-range controls update the result set in place without layout shift.
- [Machine-Readable Datasets](https://datasets.chrisyst.com/semantic-manifest.jsonl): Built-in semantic structures including NDJSON manifests, XML sitemaps, JSON-LD on every route, and parallel Markdown twins for agent extraction.

## Demonstration Directories

- [UNESCO](https://datasets.chrisyst.com/unesco/): World Heritage entities exercising geo-coordinates, inscription chronology, dual-range quantitative metrics (property area, visitor load), and multi-label cultural/natural category facets.
- [Languages](https://datasets.chrisyst.com/languages/): Linguistic census entities exercising L1 speaker magnitudes, regional coverage, language-family taxonomy, and high-cardinality categorical filters across global language records.
- [Early Humans](https://datasets.chrisyst.com/early-humans/): Hominin lineage entities exercising deep-time chronology, morphological attributes, fossil-locality geography, and cross-species comparative metrics for paleoanthropological catalogs.

## Raw Data Access

- [XML Sitemap](https://datasets.chrisyst.com/sitemap.xml): Authoritative crawl map of directory hubs and entity profile URLs for search engines and agents.
- [Semantic Manifest](https://datasets.chrisyst.com/semantic-manifest.jsonl): NDJSON stream of entities and structured fields optimized for machine ingestion.
- [Markdown Entity Twins](https://datasets.chrisyst.com/): Every entity profile publishes a clean Markdown twin at `/{slug}/index.md` (and `?format=md` under live SSR) — navigation and chrome stripped for high-fidelity extraction.
