What is this?

Solid Timeline is a Facebook-style social feed built on Solid - Tim Berners-Lee's project to re-decentralize the web. Your posts, likes, and comments are stored on your Solid pod, not a corporate server.

Your Data → Your Pod → Your Control

Features

• Decentralized - Posts stored on your Solid pod, not our servers
• Facebook-style UI - Familiar feed with posts, likes, and comments
• No build step - Pure HTML/JS, just open and use
• Solid OIDC auth - Login with any Solid identity provider
• Real RDF data - Uses SIOC vocabulary for semantic interoperability
• Works offline - Static files, host anywhere

Quick Start

Use it now

1. Go to solid-social.github.io/timeline
2. Click Login and enter your Solid IDP (e.g., solidweb.org)
3. Start posting!

Self-host

# Clone and serve
git clone https://github.com/solid-social/timeline.git
cd timeline
npx serve .
# Open http://localhost:3000

No npm install. No build. Just files.

Data Storage

Posts are stored as RDF in daily files on your pod:

https://you.solidweb.org/public/timeline/
├── 2024-01-01.ttl
├── 2024-01-02.ttl
└── 2024-01-03.ttl   ← Today's posts

Data Format

Posts use the SIOC vocabulary:

@prefix sioc: <http://rdfs.org/sioc/ns#>.
@prefix dct: <http://purl.org/dc/terms/>.

<#post-1704307200000> a sioc:Post ;
    sioc:content "Hello, decentralized world!" ;
    dct:created "2024-01-03T12:00:00Z"^^xsd:dateTime ;
    dct:creator <https://you.solidweb.org/profile/card#me> .

This means your posts are:

• Portable - Move to any Solid pod
• Interoperable - Other apps can read them
• Queryable - Use SPARQL to search
• Yours - Delete anytime, no trace left behind

Tech Stack

Layer	Technology
UI	Preact + htm
Auth	solid-oidc
RDF	rdflib.js
Build	None (ESM imports from esm.sh)

Zero build step. Everything loads from CDN via ES modules.

Configuration

The app auto-discovers your timeline from your WebID profile:

1. Looks for solid:timeline predicate
2. Falls back to {pim:storage}/public/timeline/

To set a custom location, add to your WebID:

<#me> <http://www.w3.org/ns/solid/terms#timeline>
      <https://you.pod/custom/timeline/> .
