# IndieWeb Note vs Article Distinction

The IndieWeb specification formally distinguishes two written post types based on structure, not length:

- **Article**: A post with an explicit `name` (title) property. Usually has multiple paragraphs, subheadings, blockquotes. What most people call a "blog post."
- **Note**: A post with no `name` property or an empty string name. Short, unstructured plain text. The equivalent of a tweet or toot.

The distinction matters for [Post Type Discovery](https://ptd.spec.indieweb.org/), the algorithm IndieWeb clients use to determine how to render a post:

```
if post has "name" property:
  if name != content (first N chars):
    → article
  else:
    → note
else:
  → note
```

This means a titled, categorized, tagged post with multiple paragraphs is an **article** by IndieWeb definition, even if you call it a "note" on your site. The IndieWeb "note" is specifically the titleless micro-post.

Other recognized post types: `photo`, `video`, `audio`, `bookmark`, `reply`, `repost`, `like`, `checkin`, `rsvp`, `event`. All defined by which microformat properties are present, not by an explicit "type" field.
