  '''Estimated Development Effort:'''  depends on how much SQL we decide to 
implement
  
- ==== Standard UDFs From Piggybank Need to be Moved to Pig ====
+ ==== Standard UDFs Should Pig Provide ====
- There are a number of UDFs that might be considered standard, such as UPPER, 
LOWER, etc. in Piggybank that could be moved into Pig proper so that they are 
better tested
+ There are a number of UDFs in Piggybank that might be considered standard, 
such as UPPER, LOWER, etc.  These could be moved into Pig proper so that they

- and maintained.  This is in the unknown approach section because there have 
been no discussions about which UDFs should move and to what extend Pig should 
go in
- providing "standard" UDFs.  That is, we could decide to include every 
conceivable string function, or we could just include basic ones such as upper, 
lower, and
- substring and leave the rest to Piggybank.
+ and maintained.  Also the Pig team should consider what additional UDFs 
should be added as standard.  Categories for consideration
+ include string functions, math functions, statistics functions, date and time 
functions.  We should also consider if there are
+ functions unique to Pig that we should add.  For example, it has been 
suggested that Pig should have a !MakeTuple function that would
+ take existing fields and create a tuple.
