Recent progress in the novel information technologies based on the World‐Wide Web (WWW) gives a new possibility for a worldwide exchange of atomic spectral and collisional data. This facilitates joint efforts of the international scientific community in basic and applied research, promising technological developments, and university education programs. Special‐purpose atomic databases (ADBs) are needed for an effective employment of large‐scale datasets. The ADB SPECTR developed at MISDC of VNIIFTRI has been used during the last decade in several laboratories in the world, including RFNC‐VNIITF. The DB SPECTR accumulates a considerable amount of atomic data (about 500,000 records). These data were extracted from publications on experimental and theoretical studies in atomic physics, astrophysics, and plasma spectroscopy during the last few decades. The information for atoms and ions comprises the ionization potentials, the energy levels, the wavelengths and transition probabilities, and, to a lesser extent, — also the autoionization rates, and the electron‐ion collision cross‐sections and rates. The data are supplied with source references and comments elucidating the details of computations or measurements. Our goal is to create an interactive WWW information resource based on the extended and updated Web‐oriented database version SPECTR‐W3 and its further integration into the family of specialized atomic databases on the Internet. The version will incorporate novel experimental and theoretical data. An appropriate revision of the previously accumulated data will be performed from the viewpoint of their consistency to the current state‐of‐the‐art. We are particularly interested in cooperation for storing the atomic collision data. Presently, a software shell with the up‐to‐date Web‐interface is being developed to work with the SPECTR‐W3 database. The shell would include the subsystems of information retrieval, input, update, and output in/from the database and present the users a handful of capabilities to formulate the queries with various modes of the search prescriptions, to present the information in tabular, graphic, and alphanumeric form using the formats of the text and HTML documents. The SPECTR‐W3 Website is being arranged now and is supposed to be freely accessible round‐the‐clock on a dedicated Web server at RFNC VNIITF. The Website is being created with the employment of the advanced Internet technologies and database development techniques by using the up‐to‐date software of the world leading software manufacturers. The SPECTR‐W3 ADB FrontPage would also include a feedback channel for the user comments and proposals as well as the hyperlinks to the Websites of the other ADBs and research centers in Europe, the USA, the Middle and Far East, running the investigations in atomic physics, plasma spectroscopy, astrophysics, and in adjacent areas. The effort is being supported by the International Science and Technology Center under the project ♯1785‐01.
