Hi Anastasios,
I agree with Sebastian, this tool targets advanced users so it should make
their life easier.
Some extra information on the back-end.
Error data will be stored in a triple store so we will use SPARQL for
retrieving and SPARUL for updating.
The data we will store for every error result is :
- provenance data (i.e. the test this result came from)
- multiple error classification "tags"
- specific error metadata (i.e. what is wrong with this result)
The power user should be able to read & update the aforementioned data.
Statistics target both for simple & advances users.
An option for statistics is to re-use the cubeviz Ontowiki extension (
http://cubeviz.aksw.org/).
In this case all that is needed is to convert the statistics to the
corresponding RDF Schema.
Best,
Dimitris
