Directory Services Project
February 13, 2003
3:00 pm - 4:30pm
Classroom South 514
Proposed schedule of activity - for discussion purposes
Implementation items:
Build interface as seamless unit (without needing to exit to run function).
Implement COI_Objectclass, COI_attributes LDAP data structures (cf. HICSS-36)
Select directory(ies) by browsing to, selecting URL.
Select directory from database store - pick from list of 200+ Internet2 schools
Select objectClasses, attributes, or template from "DNA" Library for clustering
Choose visual display type (SOM, LSA/SOM, SFA, text?,.)
Time lapse options. Observe clustering in process; compare different timestamp states
Directory node Analysis (DNA) Thumbprint function - snapshot of SOM map + timestamp + LDAP URL + version info.
Enable user creation of new objects (implies writable LDAP.) "What if" scenarios
Labels for SFA
Develop color maps for SFA?
Implement 3D stereo version of SFA
Implement "demo game" - can you match LDAP to vendor? Can you locate <x> fastest? Can you find most common <object>? Compare high scores? Choose your avatar (iPlanet, eDir. UMich, Georgetown.?)?
Implementation of genetic algorithms
Implementation of drill down levels of clustering & visualization
Experimental validation:
Compare SOM (1, 0) vs. SOM (Levenshtein) vs. LSA - recommendations?
Compare LSA where K=128, 92, 64. what's the best K?
Compare iPlanet experts to Novell experts to Openldap.are they different
Can clustering of standard LDAPs (out of the box) from all "major" vendors, reveal core LDAP?
Compare SFA to SOM
Compare SOMs (hexagonal, rectangular, network graph) for directories
Can DNA (Directory Node Analysis) thumbprint be useful as to identifying directory?
How certain can comparison of 2 thumbprints be?
Can library of DNA thumbprints be helpful in finding peers or exemplar LDAPs?
Efficacy of genetic algorithms
Can we build "WordNet for LDAP"?
Papers/presentations/proposals:
JMIS?
December ITR proposal - draft as paper?
Internet2 Presentation
Demo for IS&T, CIS, ACM chapter?
Web page for project
Web based demo
Using DNA thumbprint signature to identify trends and evolution of cohort groups.
Do we need experts or can we use artifacts (deployed LDAP)?
Catalog of deployed LDAPs - analysis of vendor base, objectclass & attributes
