Instance Method Details

#header ⇒ Proc

TODO:

consider a more generalized approach

Gives access to a delayed call for the ‘#header` of a parsed record.

Returns:

  • (Proc) —

    a proc that, when called, returns the #rdf_subject of the OriginalRecord associated with the parsed record passed as its argument.

def header
  RecordProxy.new(
    [{ name: :header }],
    Krikri::Parser::ValueArray,
    true)
end

#local_name ⇒ Proc

Gives access to a delayed call for the ‘#local_name` of an OriginalRecord, to be executed at the time the mapping is processed.

Returns:

  • (Proc) —

    a proc that, when called, returns the #local_name of the OriginalRecord associated with the parsed record passed as its argument.

def local_name
  lambda do |parsed|
    parsed.record.local_name
  end
end

#record ⇒ RecordProxy

Gives access to delayed method calls on parsed record ValueArrays, to be executed at the time the mapping is processed.

Returns:

  • (RecordProxy) —

    a RecordProxy providing delayed method calls against a parsed record.

#record_uri ⇒ Proc

Gives access to a delayed call for the ‘#rdf_subject` of an OriginalRecord, to be executed at the time the mapping is processed.

Returns:
