SmartOrg - How to add/delete/update data in Organization entity

Hi,

I am trying to integrate Taleo Web Service with our application . I am able to fetch/pull SmartOrg Organization entity details using FindService WSDL and export query. Similarly, I want to add/delete/update the details of Organization entity in SmartOrg using import query. I am not able to locate the WSDL corresponding to Organization entity for using import. I tried to locate the WSDL in https://[YOURZONE].taleo.net/smartorg/soap but I don't see Organization Service WSDL in it. I am seeing only below WSDL's. Please give some insight on how to edit data's in the Organization entity.
