The digitization of public sector business processes and concomitant interconnectivity of IT systems is an ongoing process in national and European terms. This affects in particular business processes of public sector identity management. Examples are the digitization of the Visa process and the introduction of the European Entry-Exit-System (EES). The implementation of the European regulation regarding interoperability is another expansion reason of the public sector identity management of Third Country Nationals. The business processes of German immigration authorities become more complicated, considering the amount of process steps that have to be fulfilled by law and the mass of involved IT background systems.

The BSI Technical Guideline TR-03156 for initial registration of Third Country Nationals (ERD) is a specification of information that has to be logged during an initial registration. These logs have to be transmitted to the BSI Data Warehouse via the BVA. This should enable an operative and databased process evaluation during an initial registration, regarding security, effectivity and efficiency. Main objective is an early identification of problems in terms of quality and process security in the complex operation sequence, implemented by the analysis of logged information by the BSI.

To be more precise, the content of this TR-03156 part is an XSD-scheme, which has to be implemented in the business application software for initial registration for immigration authorities. The scheme defines the structure for the business log data. On the one hand, data of the communication with a background system has to be logged. On the other hand, business log data of public sector identity management and connected business processes have to be recorded. The central pillar is to facilitate the complete documentation of IT process units of an identity and the communication between business application software and public sector background systems of the BVA.
Main audience of the Technical Guideline are developers of business procedures for initial registration and developers of components of these business procedures.
The Technical Guideline consists of the XSD-scheme for ERD that has to be implemented and an enclosed document, which amends the XSD-document by adding context information and further requirements.

The XSD-scheme of BSI TR-03156 ERD, published with the document, is a specification and elaboration of the requirements specified in §76b paragraph 1 clause 4 AufenthV, furthermore attachment E clause 3 and §1 paragraph 1 clause 4 AKNV, see also attachment 1 clause 5, introduced with the DÜVAnpassG.
