I want to rename some user defined fields to better group them together.
Has anybody done that before?
Can I simply edit the field-name and everything else is done automatically?
Or do I have to create a new field name and copy the old field value to the new field value?
Is the new tag name also changed in the file?

Probably.

Yes.

No, but that works too.  Edit and type =[my old field name] in the new field to quickly copy.

No.  The field display name is only for display purposes.  The internal field name is used for tagging.

Way i've done this in the past is
- create the new field
- create a smartlist to show both old field & new field.
- select all files and do a move/copy field (old->new)
- remove old field

[Matt]

Because I think this feature is neat, remember that you can quickly copy fields by editing a field and typing:
=[insert old field name]

MC works like Excel in this regard.  You can also combine fields, perform logic, etc. since it uses MC's expression language.

No doubt its neat

If i get what you are saying, when you create the new field, if you use =[old field]
then it automatically copies all the contents over from the old field and thats it, the new field is ready. It copies *all* values over to the new field.

Is it safe at this point to remove the old field then ?
..since its not needed anymore.

indeed, it's an incredibly neat feature, and yes, once done you could safely remove the old field. if you want the new field saved in the file tags too, an update tags from library would be adviseable just to get everything sync'd in one go.

expressions can also be used this way, so you can do things like =if(isequal([old field],this,8),that,or the other) and the new field would be populated with either "that" or "or the other" depending on whether or not the old field contained "this"

cool huh?

-marko.

Was just wondering..with this =[Field] thing

Would it be possible to do field to field copying (but with several fields) with it ..in effect a way to automate field-to-field copy eg
A->B
C->D
D->E

there is still a 1:1 relationship, but instead of doing  Move/Copy Field for

A->B
C->D
D->E

sequentially, it's possible to do all the 3 operatoins in 1 *GO*


I have some maintenance smartlists where i do a Move/Copy Field from one field to the other. The viewscheme is setup to only show files that need this and once they are populated the smartlist removes them from display. it only displays items if said Field is empty

Now, conceivably, if 3 expression columns were set up like

=[Field1]  =[Field 2]   =[Field 3]

When you click the smartlist, it would show the above 3 columns as populated from Fields1,2,3.

But would it also imply that the contents of those 3 fields were copied over to the coresponding three fields specified in the Expression Coulmn ?

or have i misundertood this post

I don't think there is a way to assign values of one field to another just yet

You can display them, or you can do it manually, but not automatically as i was hoping for above.
