# Content, Markdown, and generated documents

> Use Neuron's media-type pipeline to decode, transform, render, and serve content

Neuron's `InternetContent` inventory discovers encoders, decoders, converters, and file-extension mappings from installed assemblies. The same typed object can therefore be rendered differently according to `Accept`.

## Common formats

The runtime can support JSON, XML, forms, binary streams, Markdown/HTML, CSV/TSV, images, PDF, ZIP, JWT/JWS, RDF/Turtle/JSON-LD, SPARQL results, Graphviz, PlantUML, and Office documents. The exact set depends on packages and external programs.

## Markdown pages

Markdown is an application format in Neuron, not only static documentation. Page metadata can select a master page, styles, scripts, JavaScript, author/date, navigation, and other renderer-specific features. Script expressions can make content dynamic.

Use packages to deploy pages so assets, master pages, scripts, and routes are versioned together.

## Conversion pipeline

```text theme={null}
Input bytes + Content-Type
  -> decoder -> typed object
  -> optional converter chain
  -> encoder selected by Accept
  -> response bytes + Content-Type
```

Return `415` when input cannot be decoded, `406` when no acceptable output exists, and `422` when the decoded object cannot be processed/serialized for the requested operation.

## Document generation

Markdown can be rendered to HTML and, with the corresponding modules, PDF and JavaScript. Graphviz and PlantUML blocks require their runtime dependencies. Treat document conversion as resource-intensive untrusted-input processing: bound size/time, disable unsafe external includes, and isolate temporary files.

## API design

* Send explicit `Content-Type` and `Accept`.
* Do not label arbitrary text as JSON/XML.
* Keep character sets explicit for text.
* Use typed error bodies.
* Avoid depending on an optional encoder without declaring the package dependency.
