The survey was carried out by the National Library of Technology (NTK) within the CARDS project to map current coverage and planned development of these integrations. The questionnaire survey ran in autumn 2025 and addressed a sample of research institutions in the Czech research ecosystem. The analysis set comprises 198 institutions; 160 institutions (respondents) completed the questionnaire at least partially. The sampling frame covers more than 99% of research output recorded in RIV for 2022–2024. The initial frame had 199 organisations; after consolidation the analysis works with 198 institutions, and the original population weights are normalised to this base (i.e. 100% of the weighted base used throughout the report). The report is purely descriptive. It reports observed answer frequencies and does not evaluate them. Where there are notable differences between the unweighted and weighted views, the report flags them. Chapters 9–11 describe relationships in the data, qualitative inputs and plans those institutions themselves stated. The report examines five types of institutional systems (repository, current research information system / CRIS, financial management, grant management, human-resources management) and five types of persistent identifiers (DOI for grants, DOI for outputs, ORCID, RAiD, ROR).enhttp://purl.org/coar/access_right/c_abf2perzistentní identifikátoryPIDintegraceinformační systémydotazníkové šetřenípersistent identifiersPIDsintegrationsquestionnaire surveyinformation systemsanalysis/study
