1.21 +Biography
1.22 +---------
1.23 +Michael Schloh von Bennewitz is a computer scientist specializing in
1.24 +network software, mobile computing, and client server design. He speaks
1.25 +at technical events every year. In the past, he has given lectures on
1.26 +object oriented design, technical writing, network protocols, mobile
1.27 +OSs, MeeGo development, LDAP integration strategies, and the Qt library
1.28 +build process. His speaking style is humorous, using gestures and good
1.29 +eye contact. He walks about the room and writes presentations in SVG or
1.30 +HTML5.
1.31 +
1.32 +Abstract
1.33 +--------
1.34 +Given that LDAP development efforts have been few and weak, a number of
1.35 +directory relevant use cases lead to the question 'Why do so few mobile
1.36 +operating systems integrate directory client logic?'
1.37 +
1.38 +This lecture begins by explaining concepts and presenting history and
1.39 +background of directory services relating to a typical Android business
1.40 +user.
1.41 +
1.42 +Consideration of business and general use cases prove the value of LDAP
1.43 +in mobile applications integrated into the Android OS or as stand alone
1.44 +apps. A comparison is drawn to what use cases SQL covers.
1.45 +
1.46 +Advancing into the topic of what Android could provide as a platform,
1.47 +business development scenarios are discussed and what advantages
1.48 +integrating directory services bring.
1.49 +
1.50 +A technical view is given of the Android platform architecture. Third
1.51 +party implementations of applications and development SDKs are
1.52 +considered.
1.53 +
1.54 +A demonstration of developing an Android application using a well known
1.55 +LDAP Java SDK is concluded with a review of a selected business use
1.56 +case and consideration of how one would hypothetically procede.
1.57 +
1.58 +The audience consists of developers familiar with client server design
1.59 +and maybe SQL, LDAP, or other directory and database technology.
1.60 +
1.61 +Attendants expect clearly defined directory use cases, abstract
1.62 +concepts, concrete definitions, and a well explained hello world
1.63 +LDAP development example. The Android community stands to benefit
1.64 +from a collective effort at integrating LDAP wherever a strong case
1.65 +for directory service exists.
1.66 +
1.67 +The following text is a lecture outline.

1.131 + How relevant are directory services other than just for contacts?
1.132 + Why would a business not use whatever apps are already in the market?
1.133 + Why not depend on a social network for directory services?
