What it takes to become a participant
Any organisation working in or for the audiovisual production sector may apply to join the data space (opens in a new tab) Data space A decentralised infrastructure enabling trustworthy data exchanges based on commonly agreed rules. . Joining TAMIS means relying on the governance authority to certify any other participants (opens in a new tab) Participant An organisation admitted to the data space, identified under its rules and able to exchange within it. 's identity and to ensure compliance with the commonly agreed rules. Each participant uses a connector (opens in a new tab) Connector The software component a participant runs, or has run for it, to exchange data inside the data space. It enforces identity, contracts and policies. , specified by TAMIS, that ensures interoperability, policies enforcement and auditability. This page says what that involves, in the order you will meet it: what you sign up to, what we will ask you for, what it costs, and the one technical component you need.
What being part of TAMIS means
TAMIS acts as a trusted third party. By participating in the data space, you agree to declare your identity. The governing authority will verify your declarations before issuing you with the pass that will allow you to access the data space. TAMIS carries out this process for every participant. You agree to abide by a set of common rules.
What you take on
A common rulebook
The shared rules of the data space: what a participant may do inside it, and what holding credentials commits it to.
Terms and conditions
The written agreement between you and the body that runs the data space.
A verified participant identity
An identifier that is yours, and the verifiable credentials that go with it.
One or more roles
Data provider, data consumer, service provider. A participant is often several at once.
The rulebook and the terms and conditions are being written. This page will link to them the day they exist, and says so plainly until then rather than describing rules nobody has agreed.
The TAMIS governance authority is being set up as the legal entity that will hold these terms. Until it is, the terms are agreed through the consortium, and this page will say so the day that changes.
The steps, in the open
Here is the path, as it works today. Each step says what we will ask you for, and what happens next.
-
01
You register your organisation
- What we ask
- Who your organisation is on official records (opens in a new tab) Record The whole set of metadata held about one audiovisual work, kept as a single living object instead of scattered across spreadsheets and systems. , which part of the sector it works in, who to talk to, and the documents that establish it exists and that you speak for it.
- What happens next
- Your account is created and you receive the credentials to sign in. You can leave the form and come back to it: nothing is lost between two visits.
-
02
The governance reviews your registration
- What we ask
- Nothing more at this point.
- What happens next
- Your organisation's administrative details are checked. You are told as soon as the registration is validated, and the checks made on you become visible to other participants. That is what lets them know who they are talking to.
-
03
You declare your identity and your connector
- What we ask
- Two things, and they are not the same: one identifier for your organisation, and the address of the connector TAMIS should reach. If you do not have a connector yet, you choose one and run it yourself, or have a provider run it for you.
- What happens next
- An administrator verifies both and activates them. From that point you are a participant, and what you do next belongs to the data space rather than to joining it.
You are now ready to navigate the data space and to explore or publish offers.
What it costs
Taking part in the data space itself is expected to work as a subscription, scaled to the kind of participant you are: the type of organisation, its size, and the type of participation. It covers the design and upkeep of the shared building blocks. Running the connector yourself carries no TAMIS fee; having it hosted is at the provider's price.
What is collected is meant to serve the data space, not to pay shareholders. That principle is established for TEMS, whose body is a non-profit organisation. TAMIS is being built on it, and its own legal entity does not exist yet: this is what we are working towards, not a commitment already signed.
Your connector, self-hosted
No TAMIS fee. You have your own infrastructure and operating costs, and nothing else.
Your connector, hosted
At the provider's price, on the provider's terms. No TAMIS fee, unless you subscribed the offer proposed by TAMIS itself.
The data and services you consume
Negotiated bilaterally with the other participant, outside TAMIS.
No amounts, no tiers and no dates are settled. When they are, they will be published here and on the cost page rather than announced privately.

What a connector is
A connector is the door between your systems and the data space. It proves who you are, checks what was agreed with the other side, and applies the terms attached to each exchange before anything moves. It is not a database: your data stays where it already is.
Why the data space needs one
Without a connector, an exchange is just a file arriving from somewhere. The connector is what makes it attributable and contractable: both sides know who the other is, what was agreed, and can prove it later. That is the whole difference between sending data and sharing it on terms.
Two ways to run one
Run it yourself
You deploy and operate the connector on your own infrastructure. You keep full control of where it runs and what it touches, and you carry the operational load: updates, monitoring, availability.
No TAMIS fee · your infrastructure · your operations
Have it hosted
A provider runs the connector for you. You sign with that provider, on their terms and at their price. TAMIS is not party to that contract, and does not set what it contains.
Provider's price · provider's terms · TAMIS not party to the contract
Verified services, later
TAMIS governance will check that a listed service or provider is compatible with the data space, and say so. That check does not exist yet: nothing listed here has been verified by TAMIS, and no badge claims otherwise. It is written as an intention because that is what it is, and saying so is the only honest way to describe something that is planned.
Tell us what you think
The contribution model is being designed right now, which means it can still change. If a level or a way of splitting the cost would make joining easier, or would stop you from taking part at all, that is exactly what we need to hear while it is still open.
