how to know owner of report from jasperdatabase

[titaporn.c]

I have many users create a report on Jasper studio then public to jasper server, after that when we use that report or want to edit the report we don't know who can I contract with

I try to get from jasperdatabase but I can find only who edit the report on last 3 month  from  this sql 
select jr.id, jr.name, jr.label, jr.creation_date,ja.user_id, ju.username
   From jiresource jr, jiaccessevent ja, jiuser ju,jiresourcefolder jf
where jr.id = ja.resource_id
--and ja.updating = false
and jr.parent_folder = jf.id
and ja.user_id = ju.id
and jf."name" like('%Inventory_SKU_List%')
order by jr.creation_date asc

 

Do you have another way to get real person who create(public) the report to the server
