Cosmik December Lab Notes: 'Tis the season for sharing your best finds, and other Semble updates

Happy December everyone!

‘Tis the season for sharing your best finds 🤓📚☕❄

To celebrate the end of the year and get our holiday reading lists in shape, we're inviting you to make a “💎 Top picks of 2025” list on Semble.so  with books, articles, videos, tools, or anything worth passing on!

We’ll feature your picks in a special end-of-year “💎 Gems of 2025” feed on Semble. To get started, just login to Semble and follow the directions on the Home screen to create your list or view others:

Or see our Bluesky post for more details.

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:
