Open e-PRIOR is an open-source e-procurement platform that allows practical implementation of interoperable electronic services within any public administration.
It plays the role of intermediary between the back-office applications of the public administration and the Pan-European Public Procurement OnLine (PEPPOL) interoperability initiative. It has been designed to interoperate with a large number of applications of heterogeneous nature. The platform is connected to PEPPOL via its own Access Point, facilitating the cross-border exchange of e-procurement documents between, for example, a public administration in country A with suppliers in country B.
Open e-PRIOR currently covers:
e-submission, i.e. submission and opening of tenders;
post-award e-procurement, i. e. documents exchanged between the public administration and its contractors after the award of a contract, such as invoices.
The Open e-PRIOR package includes also a web portal allowing suppliers, such as SME and individuals, to manually encode their invoices via a web form.
The platform has been developed under the ISA (Interoperability Solutions for European Public Administrations) programme, by the Directorate-General for Informatics (DIGIT) of the European Commission and it was deployed within DIGIT in 2009. Other Directorate-Generals, European Agencies and Institutions are implementing the system and it is freely available to all Members States wishing to exchange standardised electronic procurement documents via secured communication channels.
The interfaces of Open e-PRIOR are based on the Business Profiles defined by CEN's workshop on Business Interoperability Interfaces for Public Procurement in Europe (CEN/ISSS WS/BII).
1. It is an integrated environment that offers web services to exchange procurement documents. The application guarantees authenticity of origin and integrity of content for all exchanged documents. It also integrates an archiving functionality.
2. It supports the integration of multiple suppliers with possibly multiple back-offices of a contracting authority.
3. It is connected to the PEPPOL infrastructure via its own turnkey PEPPOL gateway, thereby enabling the secure exchange of electronic documents via the PEPPOL network. Any supplier connected to PEPPOL has, by design, a connection to all contracting authorities which implemented Open e-PRIOR and vice-versa.
4. The application complies with:
CEN/BII Profiles (using the binding to UBL 2.0 compliant with XML 1.0 and XSD 1.1, business rules expressed as Schematron 1.5 asserts)
the e-invoicing directive
standard identifiers and standard code lists
the WS-Interoperability guidelines
In the next release in Q2 2017 the following features will be added to the Open e-PRIOR platform:
Migration of e-invoice to UBL 2.1
