%DOC with DeepSee

Hello,

I have imported my data with the following code (%DocDB).

set filename = "/home/student/Dokumente/convertcsv.json"

IF $SYSTEM.DocDB.Exists("Fitabase1") { 

SET db = ##class(%DocDB.Database).%GetDatabase("Fitabase1")

}

ELSE {

SET db = ##class(%DocDB.Database).%CreateDatabase("Fitabase1") 

}

set arr = ##class(%DynamicAbstractObject).%FromJSON(filename)

SET jstring = arr.%ToJSON()

//SET doccount = db.%Size()

DO db.%FromJSON(jstring) 

Now I have data sets like 

#     ID     %Doc                                                                                                                                                                                                  %DocumentId     %LastModified

1)How can I extract the data from %Doc, for example if I only want the ID or the ActivityDate.

2)Can I use this data in the Analyzer, DeepSee?

Thank you in advance for your help.
