
Web 2.0 (http://en.wikipedia.org/wiki/Web_2)
Trend for the next generation Web technology.
Uses a set of Web-based services—such as social networking sites, wikis,
communication tools, and blogs to enable online collaboration and information
sharing among users.
Converts web applications into a platform. Use common APIs and data sharing
interfaces such as RSS feed to construct ones own application and integrate
data from different content providers.
Generalized Webservices for Web 2.0

Service:


Out =F(In) ?
Webservice:
WSDL/SOAP, XML-RPC, Representational State
Transfer, XMLHttpRequest

Our Project


What does our project do ?
To combine Flickr, Google Map and other webservice providers (weather
service) together and provide Geographic related tagging service for online
personal photo management. Major functionality of our system include:





User authentication: authenticate user by checking ones Api-key and secret
code;
Photo management: upload/delete photos, query/update photo information,
add geographic tag to a photo (latitude, longitude and accuracy);
Photoset (album) management: add/delete photosets, move photo from one
photoset to another;
View geotags: view photo as geographic marks in a global satellite map, also
display weather of the day as additional information (only applies if location is
in US).
Export geotags: Export geographic landmarks that combine photo information
to a Google Earth KML document that can be viewed in Google Earth.

Services we used

Flickr REST services




ZK components with Google Map wrapper


Ajax-based Web User Interface, pure Java
Weather Web Service (WSDL)



http://www.flickr.com/services/api
Authentication, photo/photoset management, geodata
management, Photo upload etc
Related service provider: Zoto XML-RPC provider (upgrading)
http://www.webservicex.net/WeatherForecast.asmx?wsdl
operation: getWeatherByZipCode
Self-defined Web Service (WSDL) – Geolocation Mapping



http://kent1.galab.uwindsor.ca:8088/gqlserver/services/GeoData
Service?wsdl
Operations: getGeomappingByLatLng, updateGeomapping
Reason: hard to find a good Geolocation-postcode mapping service
