Lecture 5 A research perspective on Digital Libraries
Assumptions made in this perspective
1. Build special client and server (generally using Motif/X11, Tcl/Tk, etc.), and use TCP/IP as the transport protocol only
2. use standard protocols built upon TCP/IP: SMTP, FTP, Gopher, WAIS, HTTP, etc.
library automation track
LTRS, e-print, Netlib, etc.
ftp / gopher
Kahn/Wilensky Framework [Kahn 1995]
which consists of
Transaction record per do
from a handle
at which point the do becomes a stored do
which can go in a
Properties record per do
which registers the do’s handle with a handle server
Accesses/Deposits the do in repositories by means of the Repository Access Protocol
What the client receives as a result of an access to a do is a dissemination.
at which point the do becomes
a registered do
