Title
LEMM: community-owned clean music dataset and safety system, designed for a lean v0 prototype
1. Context and mission¶
We want to design LEMM: a community-owned, decisively clean music dataset and associated governance/safety system for training generative music models.
Key ideas:
- Contributors submit original tracks to LEMM under clear, explicit terms.
- Submitted works go into a controlled vault, not a public dump.
- There is a vetting / voting process on submissions, combining:
- Automated similarity detection against external catalogs and internal content.
- Community and/or expert review.
- Accepted tracks are used only for model training and evaluation, not for redistribution of the raw data.
- Trained models are required to:
- Not reproduce existing songs in the vault or in external catalogs.
- Provide users with outputs that can be safely licensed and used commercially.
This research is not only conceptual. It must end in a lean, technically precise v0 prototype design for LEMM, with:
- Clear technical architecture (components, APIs, data models).
- Minimal but realistic first implementation scope.
- Either:
- A concrete “build prompt” that can be handed to an engineering team or code-capable assistant to implement the prototype; or
- An explicit v0 implementation spec ready to be executed as-is.

3. Questions to answer¶
3.1 Product and policy definition¶
- What is LEMM’s mission statement in precise, implementable terms?
- For contributors: what they contribute to, what they allow, what they keep.
-
For downstream users: what guarantees they get about the models and outputs.
-
Define “clean dataset” for LEMM:
- Minimum rights LEMM must have for each track (e.g. explicit consent for training, no hidden encumbrances).
- Rights LEMM must not claim (e.g. no right to redistribute or resell raw tracks).
-
How revocation and changes of consent affect data and models.
-
Define “community-owned” in practice for v0:
- What structure is assumed (e.g. foundation-like governance vs minimal committee).
-
Who decides on:
- Admission/removal of tracks.
- Policy updates.
- Use of any revenues.
-
Define “training-only use”:
- Allowed: training generative models, evaluation, internal safety research.
-
Disallowed: streaming LEMM’s raw tracks, sublicensing the dataset, exposing per-track audio to third parties.
-
What concrete promises does v0 LEMM make, and how are they technically supported?
- To contributors.
- To model developers.
- To end-users.
3.2 Contribution and consent pipeline¶
- What does the v0 submission flow look like, end-to-end?
For each submission: - Inputs: - Audio file(s) + basic metadata (artist, collaborators, title, genre, language, year, explicit originality claim). - Steps: - User identity handling (even if minimal). - Consent capture: what exactly they agree to. - Confirmation/receipt.
- What is the minimal identity/authenticity handling for v0?
- Do we accept pseudonymous submissions with an email or account only?
- Do we need optional stronger verification for certain tiers?
-
How do we record and store “who submitted what” in the system?
-
How is consent represented technically?
- Per-track rights record: fields, enums, flags.
-
How is a change in consent (e.g. revocation) represented and propagated?
-
How does v0 protect smaller/independent artists?
- Clear consent language.
- Easy revocation or correction path.
-
Optionally, constraints on bulk submissions from single entities to keep the dataset diverse.
-
What is the minimal submission UI/UX we assume, and what backend endpoints does it call?
- Sketch the endpoints:
POST /tracks/submit, etc.- List required, optional, and derived fields.
3.3 Vetting, voting, and similarity detection¶
-
What is the v0 external similarity pipeline?
-
Choose 1–2 external sources (abstractly) to check against (e.g. a major catalog via fingerprinting API + a public open corpus).
- For each:
- What kind of fingerprint/feature is computed (audio fingerprint, embedding, etc.)?
- What similarity score is computed?
- What thresholds are used to flag a track?
Deliverable: a simple decision table for “no hit / weak hit / strong hit” and corresponding actions.
-
What is the v0 internal similarity pipeline?
-
How do we detect:
- Exact duplicates (same audio).
- Very similar tracks (e.g. re-upload or trivial modification).
- What features/fingerprints do we compute for each LEMM track?
-
How is the internal index stored and maintained?
-
What is the v0 decision flow for submissions?
-
Define state machine:
- States: submitted → pending checks → pending review → accepted → rejected → removed.
- For each state transition:
- Trigger conditions (e.g. automated checks, community vote).
-
What happens when:
- External similarity is high?
- Internal similarity is high?
- Community flags a track?
-
How does v0 voting work?
-
Who can vote (contributors, reviewers, a small trusted core)?
- What interface: simple approve/reject?
-
What thresholds (e.g. N approves, no strong objections)?
-
How does v0 handle disputes and errors?
-
False positives: process to appeal and re-evaluate a rejected track.
- False negatives: process when someone later claims infringement:
- Temporarily lock track.
- Re-run checks.
- Escalation path.
3.4 Vault architecture and governance¶
- What is the minimal vault data model for v0?
For each track, define: - Track ID. - Storage location. - Metadata (artist, title, etc.). - Rights record (consent version, scope, revocation state). - Similarity fingerprints/features. - Submission and decision history.
For the dataset overall: - Global indexes (by artist, genre, date). - Fingerprint index for fast similarity queries.
-
How is raw audio stored and protected?
-
Storage technology (abstract).
- Access control: which services/roles can read original audio?
-
Logging of access events.
-
What are the v0 roles and permissions?
-
Example roles: contributor, reviewer, admin, system.
- What each role can:
- Read (e.g. track metadata vs audio vs logs).
- Write/update (e.g. rights, metadata, flags).
-
Minimal governance rule-set:
- Who can change policies and how that is recorded.
-
What logging and audit trails exist in v0?
-
Submission and decision logs.
- Rights changes.
- Access to sensitive data (audio, detailed fingerprints).
- Minimal structure of logs (fields, retention, searchability).
3.5 Training-only usage model¶
-
How are LEMM tracks used to train models in v0?
-
Define a simple pipeline:
- Export a training subset (internally).
- Transform audio into features/representations for model training.
-
Distinguish:
- LEMM-internal training experiments.
- Models that are intended to become user-facing products.
-
How is training-only usage enforced technically?
-
Which services are allowed to access raw audio vs only features.
-
How to prevent:
- Copying raw audio out of the core environment.
- Third parties from obtaining the dataset.
-
How does LEMM interact with other datasets in v0?
-
Can models be co-trained on LEMM + other licensed sets?
- How do we keep clear metadata about:
- Which model used which combination of datasets.
- Additional constraints inherited from those other datasets.
3.6 Generation-time safety and non-reproduction¶
-
Define “too similar” for generated outputs in v0:
-
Which measures:
- Audio fingerprints?
- Embeddings?
- Symbolic similarity (if symbolic available)?
-
What thresholds or rules define:
- Allowable similarity (stylistic, generic patterns).
- Disallowed similarity (near-duplicate melody, identical audio fragments).
-
What v0 mechanisms are feasible to implement?
-
Training-time:
- Basic anti-memorization strategies (e.g. avoid overfitting, regularization).
-
Inference-time:
- Generate candidate output → compute fingerprint → compare vs:
- LEMM vault.
- One external reference index.
- Block or warn if similarity exceeds threshold.
-
What is the v0 user-facing behavior when outputs are too similar?
-
Do we:
- Reject with a message and suggest regeneration?
- Provide a high-level warning (“too similar to existing works”)?
-
What logging and internal notifications are triggered?
-
How does v0 handle prompts like “make it like [known song]” or “in the style of X”?
-
Policy stance for v0.
- How that stance is partly enforced via:
- Moderation of prompts.
- Similarity checks on outputs.
3.7 Auditability and lineage¶
-
What lineage data is stored in v0?
-
For each model version:
- Which subset of LEMM (and other datasets) was used.
- Training run ID, date, and core parameters.
-
For each track:
- Which training runs included it.
-
How can we later reconstruct:
-
A proof that a model was trained only on:
- LEMM + explicitly listed other datasets.
-
Evidence that an output was checked against:
- LEMM vault.
- At least one external catalog.
-
How does v0 handle rights changes over time?
-
If a contributor revokes a track, what happens:
- Immediately (e.g. mark track as inactive, block from further training).
- For existing models (document policy: e.g. no retroactive retraining in v0, or retraining for certain high-risk uses).
3.8 Creator licensing and economic layer¶
-
What is the minimal licensing flow for generated outputs in v0?
-
What type of license (e.g. standard non-exclusive commercial use).
- Basic terms (no need for full legal drafting, but key points and constraints).
-
UX: how a user “obtains” this license (e.g. click-through at download).
-
What assurances do we provide to users in v0?
-
That reasonable steps are taken to:
- Avoid reproducing tracks in LEMM.
- Avoid reproducing tracks in major external catalogs.
-
That we have:
- Logs and checks for generated outputs.
- Processes for addressing complaints.
-
How are contributors protected in v0?
-
We do not redistribute their original tracks.
- We do not promise more than we can technically enforce.
- Optionally: simple, documented path for future reward-sharing ideas, even if not implemented yet.
4. Prototype focus and constraints¶
The research must converge on a lean v0 prototype design for LEMM, constrained as follows:
- Scope:
- Music audio tracks only (no lyrics-only, no other media).
- Reasonable initial dataset size (e.g. conceptually thousands, not millions of tracks).
- External similarity:
- Assume at most 1–2 external catalogs / APIs for v0.
- Governance:
- Minimal but clear roles (e.g. contributors, reviewers, admins).
- Technical stack:
- Abstracted (no specific cloud vendor required), but concrete enough to:
- Define services/components.
- Define interfaces and data models.
- Safety:
- Implementable v0 similarity checks for ingestion and generation, even if approximate.
5. Artifacts and deliverables¶

- Components, APIs, storage, indexes, background jobs.
- Prioritized implementation steps (e.g. “Phase 1: submission + vault + external similarity MVP”).
- A short “build prompt” that could be given to an engineering team or code-capable assistant, phrased like:
- “Given this architecture and data model, implement v0 of LEMM’s submission and vault system with endpoints X, Y, Z…”
6. Process guidance¶
- Start with a one-page mission and constraints summary for LEMM.
- Design the v0 submission and consent flow first, with concrete data fields and endpoints.
- Specify v0 similarity and decision logic using simple tables and state machines.
- Design the vault data model and access control with logs and roles.
- Define v0 training-time and inference-time interaction with LEMM, including where similarity checks run.
- Draft the v0 prototype architecture:
- Services, storage, indexes, and background jobs.
- Interfaces between them.
- Build the risk register and minimal experiment plan.
- Finally, distill everything into the build-ready implementation prompt and a clear v0 roadmap.
7. Non-goals¶
This research does not need to:
- Provide country-specific legal contracts.
- Implement or choose specific vendors/technologies.
- Define a full economic model or revenue-sharing scheme.
- Solve all long-term governance challenges.
The goal is a coherent, technically detailed, prototype-ready design for LEMM’s data, rights, and safety system, with enough specificity to begin implementation.
8. Success criteria¶
The research is successful if it yields:
- A clear, internally consistent definition of LEMM’s mission, rights model, and constraints.
- A realistic v0 design for:
- Submission, consent, vetting, and similarity checks.
- Vault architecture, governance, and auditability.
- Training-only usage and generation-time safety.
- A concrete v0 prototype blueprint with:
- Component diagram.
- Data models.
- APIs and flows.
- Prioritized implementation steps.
- A short, explicit build prompt that could be used to drive the first LEMM prototype implementation.
