The work on the creation of the hypertext information system http://nfdfn.jinr.ru/~litvin/infosystem/hipns.html have been performed on base of the web-server of Frank laboratory of neutron physics of the Joint Institute for Nuclear Research. The work was granted by Russian Foundation of Basic Research in 1996-1997 (grant number 96-07-89189) and was initiated by the project on the creation and maintainance of the hypertext information system on pulsed neutron sources and scientific investigations based on these sources.

The initial project http://nfdfn.jinr.ru/~litvin/ADBIS96/ab1/ab1.html proposed the creation of HTML information resources and did not consider the usage of any database for the information management. During the project implementation it became obvious that the system should have well defined structured informational model and it might be helpful to imply the relational database as part of the system. The ORACLE server in LCTA of JINR have been used for this task. Now we have a set of ORACLE tables designed using CASE tools for the informational model of the system, structured information about neutron sources, neutron instruments, printed publications and URL addresses. We have also the web interface to this tables using freeware gateway ORALINK installed on our Pentium PC with Windows NT http://nfdfn.jinr.ru/~litvin/infosystem/hipns_gate.html and some tools to view pictures stored in the tables. We took into account NeXuS specifications while tried to design the informational model of the system, and we continue to work on its creation.
