GoogleKnowledgeGraph & KG ID

#1

I tried adding this to the <Parse> section of the GoogleKnowledgeGraph.xml connector, but it failed because it didn’t recognize the path I used:

<JsonPath Expr="result.@id" Id="id" Title="Knowledge Graph ID" Converter="String" DefaultValue="" HelpText="The KG:id"/>

When I deleted the @ from the path, a query no longer failed, but the ID field was blank.

The JSON path, when I tested it, was $..result.@id — I’m not sure what I’m doing wrong.

(I’d like to pull in the KG ID because with it I can create a link to the actual Knowledge Graph displayed on Google, like so:

Taylor Swift - Google Knowledge Graph ➚

Here’s a sample JSON result, provided by Google:

@ needs to be escaped by double @ sign:
result.@@id

I have updated the connector with the id field:

Ah, ha!

Excellent, thank you very much, and thanks for the escape tip!
