From this and related sessions, it seems ‘we’ are going in the right direction Tetherless World Constellation 14 Really an informatics methodology Further Information • http://tw.rpi.edu/web/project/SeSF • http://tw.rpi.edu/web/project/DCO-DS • Contact: – [email protected], @taswegian Tetherless World Constellation 16 Prior to 2005, we built systems • Rough definitions – Systems have very well-define entry and exit points. A user tends to know when they are using one. Options for extensions are limited and usually require engineering – Frameworks have many entry and use points. A user often does not know when they are using one. Extension points are part of the design – Platforms are built on frameworks 17 Tetherless World Constellation
