knowledge graph publisher — transforms markdown with wiki-links into a fast static site

any project with markdown files can publish with optica:

optica serve .
optica build .

scanner → parser → graph builder → tri-kernel → renderer → output

features: wiki-links resolution with alias support, tri-kernel ranking, namespace hierarchy with dimensional navigation, live reload with sub-second content-only rebuilds, LaTeX math, search index, graph visualization

see cyber/architecture for how optica fits in the stack

🔭 optica

knowledge graph publisher — transforms a directory of files into a fast, navigable static site. markdown pages with wiki-links are the primary content. all other files (source code, configs, data, binaries) become graph nodes with syntax-highlighted previews

optica serve .        # dev server with live reload
optica build .        # generate static site
optica check .        # validate links, find orphans

live example: cyber.page — 12K pages, 10 subgraphs, built with optica

what it does

point optica at any directory. markdown files with wiki-links become navigable pages. all other files — .rs, .toml, .nu, .json, images, binaries — become graph nodes with syntax highlighting, metadata, and backlinks. the entire repo is the knowledge graph.

features

wiki-link resolution with aliases — page, display text, page
tri-kernel ranking — PageRank + screened Laplacian + heat kernel compute per-page probability
namespace hierarchy — directories become navigable namespaces with breadcrumbs
dimensional navigation — pages with the same name across namespaces are shown as "dimensions"
sub-second live reload — content-only edits skip the full scan and rebuild in <10ms
subgraph support — import a whole repo as a subgraph via subgraph: true in frontmatter
YAML frontmatter — tags, aliases, icons, custom properties
LaTeX math — inline $...$ and block `

$$...$$

query expressions — <div class="query-results"><div class="query-results-header">Query: <code>(and (page-tags tag))</code></div><p><em>No results</em></p></div> for dynamic content
embed transclusion — `

page

- - discover all pages -

` to include other pages inline - search index — JSON search index for client-side full-text search - graph visualization — interactive force-directed minimap per page - RSS feed, sitemap, SEO metadata

quick start

# build optica
git clone <repo-url> ~/git/optica
cd ~/git/optica
cargo build --release

# serve any markdown directory
~/git/optica/target/release/optica serve ~/git/your-project --open

the scanner looks for pages in root/ (fallback: graph/, pages/). configuration via publish.toml in the project root.

page format

---
tags: topic, subtopic
alias: alternative name, another name
icon: "🔭"
---
content with wiki-links and $\LaTeX$ math

## headings become namespace children

link to other pages freely. aliases resolve automatically.

architecture

scanner → parser → graph builder → tri-kernel → renderer → output

Stage	What it does
scanner	walks filesystem, classifies files, discovers subgraphs
parser	extracts YAML frontmatter, normalizes outliner format, collects wiki-links
graph	resolves links, builds alias map, computes PageRank + tri-kernel
renderer	markdown → HTML with template support, wiki-link resolution, math
output	writes HTML, search index, graph data, sitemap, RSS

the dev server watches for changes. content-only edits (no new links, no tag changes) take the fast path: skip the scan, re-parse only the changed file, re-render only the dirty page. structural changes trigger a full incremental rebuild.

configuration

publish.toml in the project root:

[site]
title = "My Knowledge Base"
base_url = "http://localhost:8080"

[content]
public_only = false
default_public = true
exclude_patterns = [".git/*", "target/*", "build/*"]

[graph]
show_minimap = true
minimap_depth = 2

[search]
enabled = true

performance

on a 12K page graph (cyber knowledge base):

Operation	Time
full build	~28s
incremental rebuild (structural)	~12s
fast path (content-only edit)	<10ms
live reload latency	~110ms (100ms debounce + render)
