Products and data Exchange

The Products and Data Exchange, or PDX, is the collective name for the facilities that make offered and searched for data findable and available for use. With the DMI-PDX, we ensure that participants can offer and purchase products and services. Responsible and reliable are the key words. The PDX is the engine block of the DMI ecosystem: it enables data exchange in order to accelerate smart, sustainable urbanization and mobility renewal.

The PDX has five components

  • The Catalog

    The Catalog is the showcase of the DMI ecosystem: the complete overview of supply and demand for data, services, knowledge and applications can be found here. It is an online environment, built by AMS-IX. The Catalog will be available soon. Want to know what the Catalog will look like in the future, when it is well stocked and further developed? Then check out the title.

  • Identification, Authentication and Authorization (IAA).

    This is the access control system. It determines whether users represent a DMI participant and whether they have the appropriate rights to perform certain actions within the DMI-PDX and on the marketplaces.

  • Transaction module

    This section handles the financial processing of transactions between participants. The system ensures that the required information gets to the right place in the right form to enable timely and complete payment.

  • Review

    Each transaction and the parties involved are automatically and almost continuously monitored to see if they comply with the law, DMI's rules and any specific restrictions or quality requirements.

  • Log function

    All actions within the DMI-PDX are recorded. This ensures transparency, a feedback loop and provides proof in case of disputes.

I want to take advantage of the PDX!

To do so, your organization must become a participant in the DMI ecosystem. To become a participant, fill out the form on this page. After getting acquainted, we perform a test of correctness on the request for participation. Then you go through the following steps:

  1. Go through all the steps to become an ecosystem participant.
  2. Complete your organization profile using the "Organization Profile PDC" button.
  3. Request your organization's eori number from the Tax Office website. You can usually compile the eori number yourself using the "I file my own tax return" option;
  4. Make an appointment with WeCity (Annemarie Boereboom annemarie@wecity.nl) and Dexes (Joost van Dijk, joost@dexes.nl) to be informed about each of these two marketplaces. Based on the information from the conversations, decide which of the two parties you want to use;
  5. Determine which of your organization's employees should have access to the DMI-PDX, what task is assigned to whom, and what permissions are needed to do so. (Compiling an authorization list.);
  6. Consider exactly what you want to offer and/or ask for in the DMI-PDX, at what price and what "policy" or conditions;
  7. Identify which of the products and/or services you also want to offer as "Commons" that should be marked "C" in the PDC;

FAQ

We work with the "no wrong door" principle, which means that it is possible to access the entire PDX of the DMI ecosystem through different access points.

No, the data is not checked for availability elsewhere by default. But at additional cost, additional checks desired by buyer or provider can be offered by suppliers of the PDX.

The position of basic registries does not change as a result of the DMI ecosystem.

Yes, prior to the establishment of a transaction, a check is in any case carried out on whether the parties involved are Participants and comply with the rules of the Appointment System. Additional verification can be carried out upon request, possibly on a random basis. Also in the case of machine-to-machine transactions, checks will be carried out, on a random basis or otherwise.

For both marketplaces, review of authorization of individual Participant representatives is controlled from one central registry.

Yes. Each offering party chooses its own marketplace (WeCity or Dexes) to publish its offerings in the PDX, and each offering party can formulate its own policies (review criteria) that a buyer (or its use of offered data) must meet, but the review procedures are the same for cities and businesses in the case of transactions.

In principle, a foreign provider can participate in the DMI ecosystem. This party is subject to the same registration procedure and Agreements System as everyone else. A point of attention here is that the foreign party may be bound by other laws and regulations, which may "conflict" with provisions of the Appointment System. It is up to the foreign provider to make this known.

If an external data domain is linked to a marketplace in the DMI ecosystem, then transactions within the DMI ecosystem are still subject to DMI ecosystem rules.

Secure data sharing

Sharing data requires trust. You want to know who is using your data, and whether the data you take is of good quality. Several measures have been taken within the PDX to do this. First, the DMI ecosystem encourages that data be made available for use on the basis of "federated data sharing. This means that data is not moved from the source to the user or to a central platform, but remains with the provider. As a result, the owner of the data retains their "data sovereignty," control over the data, and does not have to worry about unauthorized use or transfer by others.

 

In addition, the "IAA" and "Review" functions of the DMI-PDX allow you as a provider to control who gets access to your data. As part of that IAA function, the DMI ecosystem uses iSHARE. This is a set of agreements on the basis of which it can be determined if indeed you are dealing with another DMI participant.

Commons

All participants in the DMI ecosystem must make products, services and data available to each other up to an annual value of 2,500 euros. We call this the "commons. Each participant can purchase products and services from each of the other participants for up to €2,500 as a sample. These products and services are marked with a 'C' in the catalog. This encourages all participants to explore exactly what other participants are offering. It also promotes a smooth start of adding and using data.

Cost and payment

The regular operational costs of the general facilities are paid from the participant contribution. The cost of the initial development and set-up of the PDX is co-financed by the NGF.
