Digital Object Identifiers - DOI

http://www.doi.org/

The Internet is too rich. Even powerful and sophisticated search engines, such as Google, return a lot of trash, dead ends, and Error 404's in response to the most well-defined query, Boolean operators and all. Directories created by human editors - such as Yahoo! or the Open Directory Project - are often overwhelmed by the amount of material out there. Like the legendary blob, the Internet is clearly out of classificatory control. Some web sites - like Suite101 - have introduced the old and tried Dewey subject classification system successfully used in non-virtual libraries for more than a century. Books - both print and electronic - (actually, their publishers) get assigned an ISBN (International Standard Book Number) by national agencies. Periodical publications (magazines, newsletters, bulletins) sport an ISSN (International Serial Standard Number). National libraries dole out CIP's (Cataloguing in Publication numbers), which help lesser outfits to catalogue the book upon arrival. But the emergence of new book formats, independent publishing, and self publishing has strained this already creaking system to its limits. In short: the whole thing is fast developing into an awful mess.

Resolution is one solution.

Resolution is the linking of identifiers to content. An identifier can be a word, or a phrase. RealNames implemented this approach and its proprietary software is now incorporated in most browsers. The user types a word, brand name, phrase, or code, and gets re-directed to a web site with the appropriate content. The only snag: RealNames identifiers are for sale. Thus, its identifiers are not guaranteed to lead to the best, only, or relevant resource. Similar systems are available in many languages. Nexet, for example, provides such a resolution service in Hebrew.
