Network Working Group L. Daigle Request for Comments: 2967 Thinking Cat Enterprises Category: Informational R. Hedberg Catalogix October 2000 TISDAG - Technical Infrastructure for Swedish Directory Access Gateways Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2000). All Rights Reserved. Abstract The strength of the TISDAG (Technical Infrastructure for Swedish Directory Access Gateways) project's DAG proposal is that it defines the necessary technical infrastructure to provide a single-access- point service for information on Swedish Internet users. The resulting service will provide uniform access for all information -- the same level of access to information (7x24 service), and the same information made available, irrespective of the service provider responsible for maintaining that information, their directory service protocols, or the end-user's client access protocol.
