The TTF e-logbook
Changes since the first version:
all HTML code ported to JSP (Java Server Pages)
to allow:
1. parameterization of e-logbook specific values
2. one central (XML) conf. file per e-logbook
3. access this values via JSTL (Java Server Pages
Standard Tag Library) from within every JSP files

Security: Authenti., authori.
Stepwise integration of security:
0. No authentication (2002 version)
1. (multiple-) sign on (since 2005)
2. Single sign on (SSO)
3. Cross domain SSO (CDSSO)

Conclusions
Conclusions
• Acceptance of e-logbook is overwhelming
• Ease for cloning was/is high priority
• World wide accessibility is very important
• e-logbook is a must for any kind of remote
operation
• Still much could be done (collaborations?)
10. May 2005 Technisches Seminar DESY in Zeuthen, R. Kammering
The next step …
Security
• Implement SSO authorization schema
• Extend authorization to DOOCS …
Elog-core
• Extend configurable parameters
• Harden automated elog installation
• …
