PEPPOL Transport Infrastructure Agreements (TIA):

Library of Transport Infrastructure Agreements (for sample purposes only). You can obtain the appropriate set of agreements from your chosen PEPPOL Authority.

Please see the list of PEPPOL Authorities for further information at a national level and their representatives to contact for obtaining and signing the PEPPOL Transport Infrastructure Agreements.

You can sign the TIA with any PEPPOL Authority but we recommend you choose an Authority in the country where your business is registered. Alternatively, if there is no PEPPOL Authority in your country, you could sign the TIA with OpenPEPPOL as the Authority and re-contract at a later date when an Authority is established nationally. In this case, please contact to obtain the appropriate agreements.


PEPPOL Transport Infrastructure - implementation support:

CEF e-Delivery
The Directorate-General for Informatics of the European Commission maintains sample implementation of OpenPEPPOL’s transport infrastructure. This implementation aims at providing a generic solution for public administrations to exchange documents in a secure, reliable and trusted way. The CEF e-Delivery solution provides the following components: Access Points, Service Metadata Publishers (SMPs) and Service Metadata Locator (SML).

Oxalis is a PEPPOL sample implementation for Access Points, which is used extensively in the PEPPOL community.
