Message
1. If you are serious about Free Culture & DLs, being an active member of NDLTD is a “no brainer”, with clear benefits & real savings.
2. 5S is a clear and precise framework that allows us to describe & discuss DLs.
3. 5S description of NDLTD helps facilitate understanding of how beneficial and easy it is to further develop a free culture around ETDs.

Ss Examples Objectives
Streams Text; video; audio; image Describes properties of the DL content such as encoding and language for textual material or particular forms of multimedia data
Structures Collection; catalog; hypertext; document; metadata
Specifies organizational aspects of the DL content
Spaces Measure; measurable, topological, vector, probabilistic
Defines logical and presentational views of several DL components
Scenarios Searching, browsing, recommending
Details the behavior of DL services
Societies Service managers, learners, teachers, etc.
Defines managers, responsible for running DL services; actors, that use those services; and relationships among them

Informal 5S & DL Definitions
DLs are complex systems that
• help satisfy info needs of users (societies)
• provide info services (scenarios)
• organize info in usable ways (structures)
• present info in usable ways (spaces)
• communicate info with users (streams)
![Page 9: 1 It is Easy for Universities to Support Free Culture with Digital Libraries: The NDLTD Example Edward A. Fox (fox@vt.edu) Virginia Tech, USA FCDL 2005](https://reader036.vdocument.in/reader036/viewer/2022070403/56649f305503460f94c4b44f/html5/thumbnails/9.jpg)

Hypotheses
• A formal theory for DLs can be built based on 5S.
• The formalization can serve as a basis for modeling and building high-quality DLs.

Why ETD? Short Answer
• For Students:– Gain knowledge and skills for the Information Age– Richer communication (digital information, multimedia, …)
• For Universities: – Easy way to enter the digital library field and benefit
thereby
• For the World: – Global digital library – large, useful, many services
• General:– Save time and money– Increased visibility for all associated with research results
