TITLE           TAGS: Subfields

OCCURRENCE      ARB_NT: Merge Tools / Modify Database Fields

DESCRIPTION     Tags are used to subdivide fields into subfields, which
                often have the same value. E.g. After merging the 16s databases
                from RDP and DeWachter all species have two full_names:
                The RDP and DeWachter version which should be equal but which
                are often not. So we 'TAG' the dewachter database using the
                tag 'DEW' and the RDP with the tag 'RDP'. Say one species has
                the full_names escherichia_RDP and escherichia_DEW.
                Using the tags mechanism the final field will look like this:
                        ' [DEW] escherichia_DEW [RDP] escherichia_RDP'.
                Tags are sourrounded by brackets and put in front of the 
                corresponding field value. If both subfields have the same 
                value, (like escherichia_coli) fields are merged:
                        ' [DEW,RDP] escherichia_coli'

NOTES           The Modify Database Fields tools allows to modify only single
                subfields.
                If there are no tags used yet, the default tag is taken.

                        
EXAMPLES        None

BUGS            Square Brackets in the fields are replaces by '{}'
