What is the Peppol BAIS framework?
Effective: 2019-01-01 · Authority: OpenPeppol AISBL
Peppol BAIS (Business Application Interoperability Specification) is the framework governing document exchange on the Peppol network. It defines the technical and semantic specifications for how Access Points validate, transmit, and process documents, and how participants discover each other through the SML/SMP directory infrastructure.
How does the Peppol SML/SMP directory work?
The SML (Service Metadata Locator) and SMP (Service Metadata Publisher) form the Peppol directory infrastructure. Senders look up receivers' Access Points before transmitting documents.
- SML: Central DNS-based registry mapping participant IDs to their SMP
- SMP: Per-AP metadata record listing which document types each participant can receive
- Sender queries SML to find receiver's SMP, then SMP to find receiver's AP endpoint
- All participants registered via their certified Access Point
Frequently Asked Questions
- How does a business join the Peppol network?
- A business joins Peppol by contracting with a certified Peppol Access Point provider. The AP registers the business in the SMP directory and handles document transmission and reception on their behalf. Businesses do not connect directly to the Peppol backbone.
- Is Peppol free to use?
- Peppol itself is a royalty-free network, but businesses pay Access Point providers for connectivity services. Pricing varies by AP provider and volume.
