[26] In current conditions the term "data exchange'' includes not only the exchange and distribution of data files on technical carriers, for example, on laser disks, but also providing a remote access to these data using the Internet. For the realization of this task, the IPY-Info System is developed based on the recent achievements in the web technologies, in particular, on the technologies and information infrastructure created in the scope of the Unified Information System on the State of the World Ocean (Government Resolution of 29 December 2005).

[28] Thus, the descriptions of the expeditions carried out, scientific studies, formed data sets and databases become available to a wide circle of users.
[29] The access to the data is realized on the basis of the technology of integration of distributed information resources (E2EDM) which makes it possible to perform a remote search, performance, and selection of the IPY data for scientific analysis or for specialized processing independently of their physical location.
[30] This technology makes it possible to connect up to the system information resources what would be accumulated in the IPY data centers. The following type of the data and metadata are permitted to be stored in the centers:

[32] The Integration Server Program Complex is aimed to performance of the following goals:
[33] The Data Provider Program Complex is aimed at fulfilling of the following tasks:
[34] When the Data Provider is on the side of the local data, that means that the local data system becomes a source of a system of distributed databases and this source may be involved into the automatic information data exchange At the initial stage, it is planned to connect by the E2EDM technology the information resources of the IPY data centers, and in the future to involve other organizations.
