We have successfully developed and implemented software application for the Lithuanian open access scientific information data archive. The system mainly aims to create a unified open access scientific data archive, allowing to deliver e-services, to collect and store research empirical data and other research-related information (researcher data, sources of funding and institutional data, data coding schemes, information on programs, projects and reports, publications, etc.), making it available to all those wishing to have free and comfortable access to this information over the internet.
