[Tagging] Wiki Edit War on using/avoiding semicolon lists

[Dmitry Kiselev]

 As I think,

replace
    key=val1;val2
with
     key: val1 =*
     key: val2 =*

Is just a transposition of problem.

Yes, it's easier now to test for any particular value, 
but harder to get all the values inside category.

For  key=val1;val2 you need some kind of regex 
or smarter application which allows you to find particular value inside collection.

But it's harder to get all tags in category.
How would you get all the payment methods, not the exact 'ellectrico'?

/payment:(.*?).*/ 
reg. expressions, again? 


As for  for me as a programmer, both of these approaches are the same.
But for mappers, who are normal people, not the crazy data miners

route_ref=1;2;3;4;5;123;124;125;126;234;235;236;456;457;458a

is easier than

route_ref:1=yes
route_ref:2=yes
route_ref:3=yes
route_ref:4=yes
route_ref:5=yes
route_ref:123=yes
route_ref:124=yes
route_ref:125=yes
route_ref:126=yes
route_ref:234=yes
route_ref:235=yes
route_ref:236=yes
route_ref:456=yes
route_ref:457=yes
route_ref:458a=yes

Anyway none of programmers couldn't be freed out of burden to support both of them.
But, at least we could try to establish one delimiter.
