National architectural documents

The National Architectural Documents were created on the basis of the Government Resolution No. 629 of 3 October 2018 on the "Digital Czechia" programme and the draft amendments to the Statute of the Government Council for the Information Society. In accordance with the resolution, the Ministry of the Interior ensured the publication and publication of the documents on the Information Concept of the Czech Republic (hereinafter referred to as "ICCR") website. These documents, which are collectively referred to as the ICCR follow-up documents, are:

The obligation to publish these materials by the end of September 2019 has been fulfilled with the launch of the website.

The IKCR follow-up documents develop and further elaborate on the principles and objectives set out by ICCR. The Ministry of the Interior decided to choose the form of interconnected and interlinked websites for the publication of the ICCR follow-up documents, which together form and describe the National eGovernment Architecture. This form of publication is much more useful and efficient for the information to be described in the ICCR follow-up documents and meets the requirements of the modern information society, as it supports searching over the entire knowledge base of the ICCR follow-up documents, management of individual parts/pages, change history, subscription to change notifications and other functionalities that are not possible in the form of traditional publication of paper or digital documents. In order to enable the reading of the IKČR documents offline, i.e. without an internet connection, the classical form of digital documents is also enabled, which the user can generate at will on each individual page.

Following an inter-ministerial comment procedure, the management of the National Architectural Documents, and thus the entire knowledge base, is governed by resolution of the Government of the Czech Republic of 15 February 2021 No. 159.
