3. MAPPING with AJAX and SVG Overall Presentation Goal What is MAJAS (pronounce ‘mayas’) Revealing the inside architecture Demonstrating the use of the framework (demo) Call for participation

4. MAPPING with AJAX and SVG What is MAJAS? Open source web mapping framework End-to-end GIS solution server-side: seamless integration with existing J2EE world client-side: stretching WEB 2.0 to the limit: desktop GIS in the browser?

5. MAPPING with AJAX and SVG MAJAS Server-side Architecture Java/J2EE Provides the basic concepts GIS people want: Feature: just a GIS way to look at a domain object Layer: a bunch of objects with a presentation touch (style) Map: a bunch of layers Application: a bunch of maps and some logic
