Proliferation of global observing systems and distributed scientific and operational databases challenges human abilities to comprehend effectively ever increasing volume of information about the Earth and geospace. At the same time, better communication and advent of the Internet and World Wide Web provide effective means for development of sophisticated search engines capable of identifying discipline-specific data on the Web and then retrieving requested intervals for scientific analyses or practical applications. By analogy with physical observatories deployed over the Globe and in Geospace, a concept of "Virtual Observatory" has been introduced where a personal computer can serve as an "observing" instrument that retrieves specific data from remote Internet servers and data provider nodes. Thus, collecting astronomical data from many telescopes located elsewhere in the World (and even in space) via the Internet, one can turn his/her computer to a great telescope equivalent to Hubble or Mauna Kea world-class instruments. Similar approach can turn personal computers into global magnetic, atmospheric, oceanographic, ecological (you name it!) observatories if the data from corresponding disciplines are available from the World Wide Web. Thus, we postulate here that a "Virtual Observatory" can only be deployed in cyberspace if a discipline-specific data structure (primitive or sophisticated) becomes available electronically - that is, if the appropriate "data fabric" is created in cyberspace, making itself available for search and retrieval by any software (or middleware) packages developed and installed at a single (i.e., portal-based) Internet server or at a number of personal computers (nodes) with open FTP or HTTP (or SSL and S-HTTP) ports through which specific scientific data are provided. (Generally speaking, these data may not be necessarily "scientific"; the proposed concept is applicable for "Virtual Corporation" or "Virtual Retailer" networks as well.) The presentation will address the VxO deployment challenges in relation to the 2007-2009 International Polar Year data sources and management, suggesting some immediate and intervening solutions.
