I am try to Implement a Sparql Query which will give some result.I am trying to Implement Like this: My Data points are below from where I getting the data:

Subject:

<http://rhizomik.net/semanticxbrl/0001397832_agph-20110930/Context_9ME_30-Sep-2011/ConvertibleNotesPayableTextBlock/>

Predicate:

<http:// www.w3.org/1999/02/22-rdf-syntax-ns#type>                     

Object:

<http://www.atlanticgreenpower.com/20110930#ConvertibleNotesPayableTextBlock>                       

My Query is

PREFIX ab: <http:// www.atlanticgreenpower.com/20110930#>

SELECT ?node ?val_type ?value 
  WHERE {
     ?node ab:val_type ?val_type .
     ?node ab:value ?value .
  }

I want to get the result of all subject predicate and object.I am new to sparql.please help me out

Answer 1

Try this:

SELECT * WHERE 
{ 
  ?s ?p <http://www.atlanticgreenpower.com/20110930#ConvertibleNotesPayableTextBlock> 
} 

Answer 2

In SPARQL everything with a ? in front of it is a variable. If you want everything from the subject, predicate and object you can do it like this:

SELECT ?s ?p ?o WHERE { ?s ?p ?o }

But then you list everything. When you want to only list the values of your given subject you will have to do it like this:

SELECT * WHERE { <http://rhizomik.net/semanticxbrl/0001397832_agph-20110930/Context_9ME_30-Sep-2011/ConvertibleNotesPayableTextBlock/> ?p ?o }

And your query could easily be formatted to something like this:

PREFIX ab: <http:// www.atlanticgreenpower.com/20110930#>

SELECT ?s ?valType ?value WHERE { 
  ?s ab:val_type ?valType ;
     ab:value ?value .
}

Where ; marks when you want to include something else in your query with your given subject, but . marks the end of your query. If you want more information about how SPARQL works or how you can query check out the Euclid project with webinar recording: Querying linked data, 2013-03-04 or just test it yourself on a SPARQL endpoint like from FactForge.

To reflect my comment below:

SELECT * WHERE { ?s ?p <http://www.atlanticgreenpower.com/20110930#ConvertibleNotesPayableTextBlock> } 

will select everything with the given object.
