Lab Notes #004: Semble Updates - Notifications, Provenance and Indie Integrations

Hi everyone,

Just a quick update on some new features and happenings from the past week.

New feature: Notifications!

We added basic notifications, to help spread good attention sharing karma ✨

When someone collects a card via your card, you will now receive a notification:

Provenance Field in Lexicons

Part of these notifications is tracking where someone saved a card from, so we've updating our lexicons to include a provenance section with a via field which is a strong ref to the original card record. Here's an example of what this looks like:

{
"type": "URL",
"$type": "network.cosmik.card",
"content": {
"url": "<https://lab.leaflet.pub/3m7py65pswk2e>",
"$type": "network.cosmik.card#urlContent",
"metadata": {
"type": "link",
"$type": "network.cosmik.card#urlMetadata",
"title": "Atmospheric @-mentions! - Leaflet Lab Notes",
"imageUrl": "<https://leaflet.pub/lish/did%253Aplc%253Abtxrwcaeyodrap5mnjw2fvmz/3lppk75kw7k26/3m7py65pswk2e/opengraph-image?6815eb61f733905a>",
"description": "Lab Notes 017: mention Bluesky accounts, Leaflet publications, specific posts and more to come — an interface for links across the atmosphere",
"retrievedAt": "2025-12-12T03:02:17.305Z"
}
},
"createdAt": "2025-12-12T03:02:17.305Z",
"provenance": {
"via": {
"cid": "bafyreigyya3ofkpxtpqhqtqlcny3vyvcaqfpfnzn4pikk6elt2ckvx5qcq",
"uri": "at://did:plc:rtf3bjc3w2yn4syxtm4r7jt2/network.cosmik.card/3m7q5sjs2gs2d"
},
"$type": "network.cosmik.defs#provenance"
}
}

If you include this field, the author of the referring card will get a notification that you saved their card. We’ll update the Semble PDS Client to include this field soon.

Recent Collections

Some of you have asked for this - when you add a new card you will now see your recent collections in the “Add to collections” section:

@laurenshof.online created the latest ATmosphere Report with a curated collection of interesting atproto articles from November. What's cool about this is that the curated links are now on-protocol as a Semble collection, with a custom page that lets you view them alongside ATmosphere mentions, on Semble, Leaflet and Bluesky. Check it out at https://traverse.connectedplaces.online/!

@ronentk.me vibe-coded a proof-of-concept Notion → Semble integration using our PDS client! We’re very excited by the idea of Semble as a protocolized social layer for personal knowledge tools, and AI code assistants make these bespoke indie integrations so much easier.
