HI Andy Thank you for the quick reply and the details.I'm going through the SPARQL and RDF features and getting familiar with them.
Now it's been three months out of my six months internship. I have worked in a project QA portal last month which is a portal for the QA team to manage their test data. I have used WSO2 Application server[1] which contains jaggery server component and Data service server[2] component.QA Portal front end is a jaggery application which runs on the jaggery server and DSS is used as an interface to back end MySql database. And used LDAP authentication to authenticate the user. Currently I'm working with the WSo2 CEP(Complex Event Processor)[3] team.I'm building a try it feature for the WSO2 CEP which can simulate the CEP services.
