From catalog lookup to approval

Clef keeps catalog metadata, asserted authority, reviewed evidence, policy, permission, compliance and settlement evidence as separate records. Your team can inspect the evidence behind each decision and follow every later change.

Eight records, each with its own source

Every stage writes its own record. A later stage never overwrites an earlier one, so a reviewer can see what was known when.

Catalog metadata

Recordings and compositions arrive with their identifiers: ISRCs, ISWCs and lookup results from The MLC. Clef keeps the metadata apart from any claim about who controls it.

Authority claim

The label or publisher states the right, its controlled share, the territory and the agreement behind it. Until reviewed, the claim is recorded as self-asserted.

Evidence review

A node operator reviews the supporting evidence. The claim becomes verified, disputed, rejected or revoked, and each change keeps its history.

Policy version

Catalog terms are versioned. A decision always points at the exact policy that applied when it was made.

Bounded request

A requester declares the operation, source material, durations, model environment, territory, term and accepted safeguards. Clef checks each limit against the policy.

Human decision

A named reviewer approves, narrows or declines, and attaches exact obligations: credit text, backlinks, reporting, deletion.

Signed lifecycle

The grant is signed with Ed25519. Publication, compliance evidence, disputes and revocation follow as their own signed events, linked to it.

Settlement evidence

Externally calculated royalties, payment references, payouts, reversals and reconciliation attach to the grant. A regulated provider moves the money.

The public claim register

Each capability Clef describes carries a status, a review date and a link to the source that supports it. Provisional and roadmap items say so.

Direct answers

Licenses and partners

Which software license applies today?

The released v0.1.0-alpha.1 uses AGPL-3.0-only. The proposed Own-Node and Partner Licenses apply to a future source-available release once adopted. Earlier grants and component licenses continue to apply.

Can we use Clef commercially for our artists and writers?

Yes. The proposed Own-Node License permits an organization’s own rights administration, including catalogs it genuinely represents. Revenue from administering and licensing those rights is within that scope. The released alpha follows its AGPL terms.

Who can install and maintain our future own-node release?

Your employees can self-install and use coding assistants. Clef can provide setup under a services agreement. An outside installer or maintenance provider needs a separate Clef Partner License covering your organization.

Can our consultancy sell Clef installation and support?

Offer setup, catalog imports, branding, integrations, staff training and ongoing maintenance. You set your service prices and retain that service revenue. Clef provides the software and shared technical documentation. US$1,200 per client organization, billed annually. Each partner’s first client receives a first-year price of US$600; renewals and additional clients are US$1,200 annually. Activation fee: US$0. Applicable taxes are additional. The proposed standard partner license authorizes these services for registered client organizations.

Can we host clients, distribute an OEM edition or resell the software?

The standard program covers installation and support in the client organization’s infrastructure. The client controls its catalog data, access and licensing decisions. Partner-hosted services, OEM distribution and other resale require a separately scoped agreement.

Who helps the customer, and what happens if the partner leaves?

You provide day-to-day customer support. Clef provides shared documentation and software issue channels; bespoke assistance is scoped separately. If a partner stops renewing, its commercial service entitlement ends. The client keeps its applicable own-node rights, records and exports and can self-administer or select another licensed partner.

How do the two pilot offers differ?

The partner first-client offer is separate from the 50% discount on Clef-assisted pilot setup fees. The partner offer reduces one annual partner license; the Clef-assisted offer reduces the agreed setup service fee.

Does applying activate a partner license?

The form records interest and delivers the proposed offer. Activation follows a completed agreement, eligibility checks and the designated software release.

Records, evidence and payment

How is authority reviewed?

The label or publisher identifies the right, controlled share, territory and supporting agreement. A node operator reviews that evidence. Authority records distinguish self-asserted, verified, disputed, rejected and revoked claims. Each permission has its own term, decision and history of later corrections, disputes or revocation.

How does Clef use data from The MLC?

Authorized lookups from The MLC help identify musical works and review publishing claims in its U.S. administrative context. Recording metadata is supplied to The MLC by DSPs and processed as received. The label or other recording rightsholder supplies evidence of master ownership and controlled shares; publishers supply their mandates and territorial scope. Your reviewers use those records to decide each requested permission.

Does Clef send DDEX messages to PROs or CMOs?

The alpha validates Musical Work Licensing (MWL) files against specified DDEX schemas and records exchange evidence. Production transport, counterparty conformance, and legal effect require a bilateral operating arrangement.

How are credit and backlinks enforced?

The administrator can require exact text, URL, placement, metadata, and reporting in the signed grant. A requester reports publication, an administrator records compliance evidence, and any dispute or revocation remains a separate signed action.

How are royalties and payments recorded?

Clef records externally calculated royalties, payment evidence, beneficiary payouts, reversals, and reconciliation. A regulated provider remains responsible for money movement and related duties.

Can an organization use Clef for non-AI permissions?

Yes. The same workflow supports other music uses through catalog policies, evidence review, approval records, and reporting.
