# Content Types

Sitebase is designed to be flexible and work with any `standard.site` data. However, due to the potential complexity of working with app-specific content types like those of leaflet.pub or pckt.blog, currently support is limited for working with them.

As defined in [the lexicon documentation](./lexicons.md), sitebase defines two simple content lexicons: `pub.sitebase.content.html` and `pub.sitebase.content.markdown`.

## Content Type Handling in CLI

The CLI only supports editing documents with sitebase content types:

| Content `$type` | `doc edit` | `doc view` | `doc export` |
|-----------------|------------|------------|--------------|
| `pub.sitebase.content.markdown` | Supported | Supported | Supported |
| `pub.sitebase.content.html` | Supported | Supported | Supported |
| Other (pckt.blog, etc.) | Blocked | Supported (raw display) | Supported (raw content) |

When `doc edit` encounters a non-sitebase content type:

```
Error: Cannot edit document with content type "blog.pckt.content.block"
Sitebase only supports editing documents with pub.sitebase.content.* types.
Use `doc view` to inspect the document.
```
