You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: handler.rb
    path of file: ./repos/archivesspace/_yard
    
    the code of the file until where you have to start completion: # class RSpecDescribeHandler < YARD::Handlers::Ruby::Base
#   handles method_call(:describe)
#   
#   def process
#     objname = statement.parameters.first.jump(:string_content).source
#     if statement.parameters[1]
#       src = statement.parameters[1].jump(:string_content).source
#       objname += (src[0] == "#" ? "" : "::") + src
#     end
#     obj = {:spec => owner ? (owner[:spec] || "") : ""}
#     obj[:spec] +=
    
  def process
    name = parser.file.sub(/\.rb/, '').sub(/.*\//, '') + "_schema"
    schema_object = register YARD::CodeObjects::SchemaObject.new(:root, name)
    
    schema_object[:schema] = schema_object[:source] = statement.to_s

    accession_browse_column_enum, resource_browse_column_enum, digital_object_browse_column_enum = nil
    
    s = eval("#{schema_object[:source]}")
    return "" unless s.is_a?(Hash) 
    
    schema_object[:uri] = s[:schema]["uri"]
    schema_object[:properties] = s[:schema]["properties"]


  end
