2 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 The PEPPOL project Pilot A objective: Enabling EU-wide public eProcurement 50% EU contribution for achieving interoperability Coordinated by the Norwegian Agency for Public Management and eGovernment (Difi) Consortium and scope: 18 beneficiaries from 12 countries Total budget 30,8 M€ 8 work packages, <1.600 person months and 10 M€ on sub-contractors Project start up: 1 May 2008, duration 48 months* *Current project duration is 42 months (+6 months extension subject to European Commission's approval) The PEPPOL project is the result of the European Competitiveness and Innovation Programme (CIP) ICT Policy Support Programme (ICTPSP) 2007 and 2009 Call for Proposals

3 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 Any supplier (incl. SMEs) in the EU can communicate electronically with any European contracting authority for all procurement processes. The PEPPOL Vision 3

5 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974Page 5 Service Metadata Publisher and Identifiers

6 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 How does it work (simplified)? A URL is build based on the receving partipcant’s ID, and the domain of the PEPPOL central locator A bit simplified: http://SE5523222312.sml.peppolcentral.orghttp://SE5523222312.sml.peppolcentral.org Points towards registry ABC And http://DK4723222753.sml.peppolcentral.org Points towards registry XYZ http://DK4723222753.sml.peppolcentral.org Exactly as http://mail.ecru.se points the our mail server and http://www.ecru.se points to our web server (located and hosted by different providers)http://mail.ecru.sehttp://www.ecru.se The URL is built using the same mechanism ALL THE TIME You only need to know the participant’s identifier to retreive the necessary data for the service that receives the documents

7 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 And the response from the registry The receivers identitier Type of supported process Type of supported messages (and customizations) Type of supported transport protocol/profile Technical address where to send to

9 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 PEPPOL Policy for using Identifiers Page 9 Party identifiers Party Ids in START/SMP 0088:4035811991014 Party Ids in Messages 4035811991014 0088 and GLN are used as examples. The policy for identifiers document lists a number of schemes inlcuding VAT-numbers, Company regitration number, IBAN and DUNS.

10 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 PEPPOL Policy for using Identifiers Page 10 Document identifiers Used in SMP to specify what document type a certain service accepts Informs about the syntax/format, the customization and a version urn:oasis:names:specification:ubl:schema:xsd:Invoice- 2::Invoice##urn:www.cenbii.eu:transaction:biicoretrdm010:ver1.0:#urn:w ww.peppol.eu:bis:peppol4a:ver1.0::2.0

11 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 PEPPOL Policy for using Identifiers Page 11 Customization Used in in CEN/BII to specify the contextualization/customization of a certain document. A stand alone invoice may differ content-wise from an integrated procurement invoice. urn:www.cenbii.eu:transaction:biicoretrdm010:ver1.0:#urn:www.peppol. eu:bis:peppol4a:ver1.0 urn:oasis:names:specification:ubl:schema:xsd:Invoice- 2::Invoice##urn:www.cenbii.eu:transaction:biicoretrdm010:ver1.0:#urn:w ww.peppol.eu:bis:peppol4a:ver1.0::2.0 The transaction datamodel (the allowed business terms and rules) Optional extension to the rules Version of the customization

12 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 PEPPOL Policy for using Identifiers Page 12 Remember this The receiving party publishes what documents it supports The sender must make sure that the actual instance corresponds to the supported type Many implementations may implement the DocumentIdentifier as a string- constant without actually using all the ”hidden” information

13 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 Service Metadata

16 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 The PEPPOL Infrastructure Service Metadata Locator (SML) Central part of the PEPPOL Infrastructure, hosted and managed by the consortium DNS-based resolve of participant identifiers, to locate a participants related SMP, 1-To-1 relation. Provides an interface to associate/deassociate participants with SMPs Service Metadata Publisher (SMP) Provides detailed information about participants -What documents/processes are supported -To which endpoint (URLs) supported documents should be propagated Anyone can host a SMP, but a provider agreement with a PEPPOL Regional Authority is necessary

19 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 Known pitfall with hashing of participants Page 19 The MD5 hash-algorithm is case sensitive 0007:se1122334455 produces: ae58dc2c699074f5a9372bd4a370a273 Correct 0007:SE1122334455 produces: 62c82af5bdc937c6fe55c1ff6bea19e1 Incorrect! Always use lower case letters in alphanumeric identifiers when calculating hashes in the PEPPOL infrastructure.

20 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 Access of SMP resources Page 20 When the location of an SMP has been determined through an SML-Lookup, the process can then continue by querying the services provided by the resolved SMP. SMP Provides: REST-based interface for retrieving participant information Two types of services/resources MUST be defined: ServiceGroup SignedServiceMetadata Redirect functionality for multiple associations of a participant

22 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 ServiceGroup Page 22 The ServiceGroup service provides information about all services associated with a specific participant identifier that is handled by the SMP. Presents a list of references to SignedServiceMetadata resources Pseudo response: 0007:SE1122334455

24 PEPPOL is an EU co-funded project CIP-ICT PSP-2007 No 224974 SignedServiceMetadata Page 24 The SignedServiceMetadata service provides information about electronic services supported by a recipient. It associates a participant identifier with the ability to receive a specific document type over a specific transport protocol. Provides details about service Means of redirection is another SMP handles this service Response contains a private signature Pseudo response:
