RDF2Any for CSV includes the unique identifier of the object in a column #62

Closed smouzakitis closed 9 years ago

RDF2Any for CSV includes the unique identifier of the object in a column. For example take a look at the https://health.data.ny.gov/api/views/hbu9-xsrx/rows.rdf . The "http://health.data.ny.gov/resource/hbu9-xsrx/1" in "rdf:about="http://health.data.ny.gov/resource/hbu9-xsrx/1" should be included in a column in each row.

This has been tackled, please check that it is ok.

Thanks for including the unique reference id of each instance at the query , constructed by the Query builder. Playing around with the Query Builder deployed at Linda Workbench i saw for the case of dbpedia that the first column "url" is exactly what we need. But I could not use the query builder for any other datasource of the LindaWorkbench such as the "Radon-Test-Results-By-Town" or " NYRandonResearch Linear Regression Analytic Result". How i could run the Query Builder for these type of datasources???

You should be able to do that just by passing the sparql endpoint for the dataset you need as a parameter in the api call.

efotopoulou commented 10 years ago

The datasets i try to construct the sparql query on (by using the Query Builder) have no sparql endpoint. They are private datasets , come from rdf dumps. The current deployed version of Query Builder does not detects the classes in them. Hope i have understood fine your explanation if it is not the case we could do a skype! Thanks for the quick response!

Since the Query Builder is intended to be used within the LinDA framework, you can only use the it with datasets with a SPARQL endpoint. Private datasets, in order to be used, should first be uploaded to linda and accessed through a SPARQL endpoint.

Hi Judie, yes you can only access datasets uploaded or linked to the LinDA store. For instance someone has uploaded Radon-Test-Results-By-Town (see here http://107.170.70.175:8000/datasources/). I right-click and choose explore. The query builder does not detect the classes. I think you only test your tool only with dbpedia. It will really help you with testing if you use 2-3 data sources other than dbpedia. Also the autocomplete list of all available classes will make things clearer.
