How to get all minimum values for a table of unique records?

Question

I need to get the list of minimum value records for a table which has the below structure and data
create table emp (name varchar2(50),org varchar2(50),desig varchar2(50),salary number(10),year number(10));
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',3000,2005);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',4000,2007);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',7000,2007);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',7000,2008);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',7000,2010);
commit;
SELECT e.name,e.org,e.desig,min(e.year) FROM emp e,(
SELECT e1.name,e1.org,e1.desig,e1.salary FROM emp e1
GROUP BY (e1.name,e1.org,e1.desig,e1.salary)
HAVING COUNT(*) >1) min_query
WHERE min_query.name = e.name AND min_query.org = e.org AND min_query.desig =e.desig
AND min_query.salary = e.salary
group by (e.name,e.org,e.desig);With the above query i can get the least value year where the emp has maximum salary. It will return only one record. But i want to all the records which are minimum compare to the max year value
Required output
emp1     org1     mgr     7000     2008
emp1     org1     mgr     7000     2007Please help me with this..

Frank,
Can I write the query like this in case of duplicates?
Definitely there would have been a better way than the query I've written.
WITH      got_analytics     AS
     SELECT     name, org, desig, salary, year
     ,     MAX (SALARY)  OVER ( PARTITION BY  NAME, ORG, DESIG)          AS MAX_SALARY
     ,     ROW_NUMBER () OVER ( PARTITION BY  NAME, ORG, DESIG, SALARY
                                ORDER BY        year  DESC
                       )                              AS YEAR_NUM
       FROM    (SELECT 'emp1' AS NAME, 'org1' AS ORG, 'mgr' AS DESIG, 3000 AS SALARY, 2005 AS YEAR FROM DUAL UNION ALL
SELECT 'emp1','org1','mgr',4000,2007 FROM DUAL UNION ALL
SELECT 'emp1','org1','mgr',4000,2008 FROM DUAL UNION ALL
SELECT 'emp1','org1','mgr',7000,2007 FROM DUAL UNION ALL

SELECT     name, org, desig, salary, year

Result:

SELECT     name, org, desig, salary, year
