  1. Serving up Beyond 2020 files on the WWW DLI workshop - Ontario region March 30, 2000 University of Guelph

  2. Unix WWW server environmentLaine Ruus, University of Toronto Data Library Service Windows NT WWW server environment Walter Giesbrecht, York University Library Data Services

  3. With acknowledgements toVince Gray, UWO/SSCL who first discovered this was possible!

  4. What we’ll be talking about: • advantages to serving up B20/20 files via a WWW server • how to do it in a Unix environment • how to do it in a Windows NT environment • how to create the HTML files you’ll need • links to more information

  5. Alternatives to providing access to Beyond 20/20 files : • pass-through: lending CD-ROMs • pass-through: copy of ftp’d files to user • install on stand-alone workstations • install on a LAN • serve WWW plug-in such as WinFrame (ICA or RDP-based) • serve as full WWW helper application

  6. Advantages to serving up Beyond 20/20 files via WWW [1] • allows you to serve files regardless of the original file medium • provides 24x7 remote access • ability to customize the interface • sidestep limits of indexing of individual products • integrate files from different editions and products

  7. Advantages to serving up Beyond 20/20 files via WWW [2] • more secure than loaning out CD-ROM • less competition for disk space on LAN servers or stand-alones • doesn’t require dedicated CD-ROM drive • faster access than e.g. WinFrame • by-passes installation problems

  8. Major types of B20/20 files • table files -- for aggregate statistics • extract files -- for microdata • map files -- for data visualization

  9. B20/20 files that can be served via WWW • table files • standard WWW server • users need B20/20 client software • alternatively with Beyond 20/20 web data server (NT-based) • extract files • very kludgy • Ivation server plans to do this sometime in 2000

  10. Serving B20/20,Unix fashion [1] • server must be configured with correct MIME type • application/x-beyond2020 • file extension .ivt

  11. Serving B20/20,Unix fashion [2] STC ‘limited use’ contract requires DLI and DSP files be available: • to faculty/students/staff of your academic institution • (DSP only) walk-in users of your library • files must be restricted access • IP-address protected, or • account and password protected

  12. Serving B20/20,Unix fashion [3] • if CD-ROM product • upload all .ivt files to appropriate directory on server in binary mode • if product obtained via ftp as compressed file • .zip or .exe extension • uncompress using unzip • or uncompress in Windows and upload

  13. Serving B20/20,Unix fashion [4] • make subdirectory(ies) containing files ‘world’ readable and executable • make file(s) ‘world’ readable • command: chmod 755 * (read & execute) or chmod 744 * (read only)

  14. Serving B20/20,Unix fashion [5] • store or link subdirectories/files within WWW server area, command: ln -s [existing_path/filename] [newname]

  15. Serving B20/20,Unix fashion [6] And, finally……………. • edit the ivtables.dir or ivtables.fra file to make an HTML page for the item • store the HTML file in either WWW server area or a linked subdirectory • TEST the HTML document before releasing it.

  16. ….and now....

  17. Serving B20/20,WinNT fashion [1] • server must be configured with correct MIME type • application/x-beyond2020 • file extension .ivt • access must be restricted

  18. MIME type configuration Access configuration … from Internet Service Manager console

  19. Serving B20/20,WinNT fashion [2] • if CD-ROM product • copy/upload all .ivt files to appropriate directory on server in binary mode • if product obtained via ftp as compressed file • .zip or .exe extension • uncompress using compression utility (e.g., WinZIP)

  20. Serving B20/20,WinNT fashion [3] Creating virtual directories

  21. Serving B20/20,WindowsNT fashion [4] And, finally……………. • edit the ivtables.dir or ivtables.fra file to make an HTML page for the item • store the HTML file in subdirectory (real or virtual) of \wwwroot • TEST the HTML document before releasing it.

  22. B20/20 via HTML [1] • use the ivtables.dir found in the directory with the .ivt files
