GSoC2013_Lazaros_Progress
This project is about a power tool that will list and visualize all the validation errors produced by the validation framework. The errors will be annotated with metadata that can be edited using the power tool.
The proposed application will work in conjuction with the upcoming DBpedia validation framework.
The framework will submit requests against the DBpedia triple store to track down various errors. For instance, given a person, their birth date should always be prior to their death date. These tests will be defined by the community and their results will be stored as triples in a separate triple store. The results will be accompanied by metadata (following a defined schema), as the test details, the error information etc.
The application will focus on giving tbe users a quick summary of the current state about validation tests and provide an easy way to tackle validation issues with few clicks. The users (power users of DBpedia) will be able to view aggregate information based on the errors and their metadata (e.g. how many countries have a prime minister that is dead?). The errors metadata will be editable through the application, so that the users can classify the errors and make it easier for others to navigate. The application will be designed so that it can be configured to work with other datasets and validation schemes.
