http://www.w3.org/Proposal.html
WorldWideWeb: Proposal for a HyperText Project
To: P.G. Innocenti/ECP, G. Kellner/ECP, D.O. Williams/CN
From: T. Berners-Lee/CN, R. Cailliau/ECP
Date: 12 November 1990
Future paths
Future developments which would further enhance the project could include:
Daemon programs which run overnight and build indexes of available information.
A server automatically providing a hypertext view of a (for example Oracle) database,
from a description of the database and a description (for example in SQL) of the view
required.
Work on efficient networking over wide areas, negotiation with other sites to provide
compatible online information.
A serious study of the use and abuse of the system, the sociology of its use at CERN.
