David H. Lorenz is an Associate Professor in the Department of Mathematics and Computer Science at the Open University of Israel, and a Visiting Professor at the Faculty of Computer Science, Technion—Israel Institute of Technology.

His research interests include aspect-oriented and language-oriented software engineering, modularity, and programming, particularly involving domain specific languages. He is the former chair of the AOSA, a non-profit organization whose mission is to be the primary sponsor for the annual conferences: International Conference on Aspect-Oriented Software Development; International Conference on Modularity; and International Conference on the Art, Science, and Engineering of Programming.

Prof. Lorenz received his PhD in computer science from the Technion—Israel Institute of Technology. He’s a member of the ACM and a member of the IEEE. Contact him at the Dept. of Mathematics and Computer Science, Open University of Israel, Raanana 43107, Israel; lorenz@openu.ac.il.

Too

About this project להלן תיאור הפרויקט הנדון. מגרש המשחקים של שפת TOO מגרש זה אמור לפעול בדומה למגרש המשחקים של שפת GO; לאפשר כתיבה והרצה של תוכניות בלחיצת כפתור וכמובן לראות את תוצאות הריצה.

Acquisition

A new abstraction mechanism in which objects “inherit” properties from the containment hierarchy they’re in.

Application Embedding

A novel approach to application development that allows all aspects of an application, including its business-logic, to be programmed declaratively.

Awesome

A language workbench for domain specific aspect oriented languages

Cedalion

A Programming Language for Language Oriented Programming

Cloudlog

A data representation and query language for a new family of NoDatalog deductive databases.

Component-Based Design

“Pluggable Reflection: Decoupling Meta-Interface and Implementation.” Co-authored with John Vlissides, observes that reflection remains a second-class citizen in current programming models, where it’s assumed to be imperative and tightly bound to its implementation.

Ink

An adaptive object model (AOM) framework with built-in support for DSLs.

ModelTalk

When Everything Is a Domain-Specific Language

Perscope

Decoupling Aspect Instantiation and Implementation

XRC

Crosscutting Revision Control System
