Minimal markdown formatting

[melvincarvalho]

Summary

Define a minimal set of markdown formatting that chat clients should support for message content in sioc:content.

Proposed Syntax

Syntax	Renders as
*bold*	bold
_italic_	italic
~strikethrough~	strikethrough
`code`	code

Rationale

• Familiar syntax (Slack, Discord, WhatsApp all use similar)
• Simple to implement (~10 lines regex)
• No ambiguity with RDF content
• Graceful degradation (readable even without rendering)

Scope

This is about the text syntax stored in sioc:content. Rendering is implementation-specific.

Questions

1. Should we support **bold** as an alternative to *bold*?
2. Should we support multi-line code blocks (triple backticks)?
3. Should we support links [text](url)?
