DP1 Provenance Block Update#

Summary#

This update adds provenance blocks to all KidLisp playlists according to the DP-1 specification.

Changes Made#

1. Updated Playlist Generation Scripts#

All playlist generation scripts now include offchain provenance blocks:

✅ create-top-kidlisp-playlist.mjs - Top 100 KidLisp pieces
✅ create-kidlisp-colors-playlist.mjs - CSS color exploration
✅ create-kidlisp-chords-playlist.mjs - Musical chords

Provenance Block Format:

provenance: {
  type: 'offChainURI',
  contract: {
    uri: 'https://aesthetic.computer/$code',
  }
}

2. Created Regeneration Script#

File: regenerate-kidlisp-playlists.mjs

This script automates the complete regeneration process:

Finds and deletes existing KidLisp channel
Finds and deletes all existing KidLisp playlists
Regenerates all playlists with provenance blocks
Creates a new channel with all the updated playlists

Usage:

cd /workspaces/aesthetic-computer
FEED_API_SECRET=your_secret node feed/regenerate-kidlisp-playlists.mjs

Why Provenance Blocks Matter#

According to the DP-1 spec, provenance blocks:

Link rendered assets to their source of truth (on-chain or off-chain)
Provide verifiable documentation of artwork origins
Support future tokenization and rights management
Enable proper attribution in display contexts

Provenance Types#

The DP-1 spec supports three types:

onChain - Explicit contract (ERC-721, FA2, etc.)
seriesRegistry - Parent collection in SeriesRegistry
offChainURI - URI points to canonical source ✅ (used here)

For KidLisp pieces, we use offChainURI since they're not yet tokenized but have canonical URLs.

Next Steps#

To Regenerate Your Playlists:#

# Set your Feed API secret
export FEED_API_SECRET="your_actual_secret_here"

# Run the regeneration script
cd /workspaces/aesthetic-computer
node feed/regenerate-kidlisp-playlists.mjs

Future Tokenization#

When KidLisp pieces are minted as tokens, update the provenance to:

provenance: {
  type: 'onChain',
  contract: {
    chain: 'tezos',
    standard: 'fa2',
    address: 'KT1...',  // Your FA2 contract address
    tokenId: '42',       // Token ID
    uri: 'ipfs://...',   // Token metadata URI
  }
}

Verification#

After regeneration, verify playlists include provenance:

# Get playlist and check for provenance field
curl https://feed.aesthetic.computer/api/v1/playlists/{id} | jq '.items[0].provenance'

Expected output:

{
  "type": "offChainURI",
  "contract": {
    "uri": "https://aesthetic.computer/$code"
  }
}
