On 1st July 2012, the Czech eGovernment has got a new engine. Obviously, we are talking about the Basic Registers, which have been in operation for three months now and create one of the crucial elements of the public administration´s information systems in the Czech Republic. Asseco Central Europe has contributed in building the two “cylinders” of the engine: Register of Legal Entities, and Register of Rights and Obligations (RRO). With emphasis on the mentioned registers (especially RRO), the presentation will focus on the basic functionality and the architecture of the registers. Moreover, it will center on the topic of integration process of the agenda´s information systems with the external interface of the Information System of the Basic Register, as well as on the developing potential of the complex solution.
