Why successful?

Monday 30 March 2009

Why successful?•open systems approach

•standardized specifications for interoperability

•backwards compatible with legacy data(can access gopher, ftp, news, wais, ...)

•designed to be decentralized:

•no central link database (hence consistency less assured)

•no ‘compilation’ into specific format
