Governikus COM Despina DVDV/OSCI Edition, hereafter Despina DVDV/OSCI, provides access to the secure OSCI transport infrastructure for specialized procedures of public authorities. Thanks to the XTA web service interface, Despina DVDV/OSCI realizes the communication between specialized and transport procedures, independent of the communication protocols used for transport.

COM Despina supports both DVDV-based OSCI application scenarios (COM Despina DVDV/OSCI Edition) and Peppol-based AS4 communication (COM Despina Peppol/AS4 Edition).

4-Corner Model for OSCI Communication

4-Corner Model for OSCI Communication

OSCI (Online Services Computer Interface) forms the standard for secure data transmission in Germany. Authenticity, integrity, non-repudiation and confidentiality in communication can be guaranteed with OSCI messages. Logging and acknowledgement mechanisms make "electronic registered mail with return receipt" a reality. The high requirements of data protection are taken into account by encrypting all messages "end-to-end".

Communication between transport procedures and specialist applications in e-government

In complex e-government applications, it may make sense to divide up specialized procedures and transport procedures. This is where XTA comes into play: true to its name (XML in Public Administration Transport Adapter), XTA makes use of the XML standard. Consequently, an XTA message is nothing more than an XML file. In order for the exchange of messages from author:in to reader:in to be automated, fixed message structures are necessary. KoSIT has established a standardization of XTA messages via XÖV standards for the communication from authority to authority. These are continuously being developed further.

In addition to a specification and a transport profile, an XÖV standard also consists, among other things, of schema files that clearly specify the structure of permissible messages of this standard. These so-called XSD (XML Schema Definition) define the structure of the XML files and consequently of the XTA messages.

The standard for secure, confidential and legally binding data transmission

Each transport protocol defines specifications for the structure of a message to be transmitted via it. If a specialized message is to be transmitted via OSCI, it must be converted into a corresponding OSCI message. The information required for the conversion is available in the configuration of the sender on the one hand and in the specialized message on the other. In order to automate the process of creating a specification-compliant transport message, scenario templates are created. These ensure that a specification-compliant subject message becomes a specification-compliant transport message.

Scope of XÖV standards

The full support of an XÖV standard includes for Governikus COM Despina:

The provision of necessary resources on the file manager master for synchronous as well as asynchronous procedures

The necessary adaptation of the default configuration of Governikus COM Despina to use the new XÖV standard.

The creation and regular execution of tests for sending and receiving appropriate XTA messages.

Regular updating of resources and tests according to KoSIT specifications promptly on 01.05. as well as 01.11. of each year.

Despina DVDV/OSCI and new XÖV scenarios

All supported XÖV scenarios are made available to the COM Despina DVDV/OSCI Edition via the Governikus Suite file manager. Which XÖV scenario is supported as of which COM Despina release can be found in the following table or in the document in the download area at the bottom of the page.

According to current planning, COM Despina will support these XÖV standards on 01.05.2023:

  • XFamily 0.3 Pilot and
  • XSocial-base 1.0.
