2. Some history 1992: DLP -- A language for Distributed Logic Programming Wiley 2000: Principles of Object-Oriented Software Development Addison-Wesley, 2nd edn. 1995: Programming the Web -- A search for APIs, WWW5 1996: Logic Programming for the Web, WWW6

3. JAVA a second generation third generation programming language

4. basic architectural entities active objects multithreaded symbolic objects

6. local object services - incremental loading - code migration

8. distributed object services - naming and references - location transparency

9. cooperation and synchronization (conditional) accept statements rendez-vous

10. language characteristics - multithreaded active objects - method marshalling - (a)synchronous communication primitives - garbage collection - mobile code support - distributed object trader services DLP

12. conclusions the Web needs (distributed) logic programming for knowledge-intensive applications DLP on top of Java is a suitable candidate … we strive for efficiency
