| 11 | TITLE TAGS: Subfields |

| 15 | |

| 16 | DESCRIPTION Tags are used to subdivide fields into subfields, which |
|---|
| 17 | often have the same value. E.g. after merging the 16s databases |
|---|
| 18 | from RDP and DeWachter all species have two full_names: |
|---|
| 19 | The RDP and DeWachter version which should be equal but which |
|---|
| 20 | are often not. So we 'TAG' the dewachter database using the |
|---|
| 21 | tag 'DEW' and the RDP with the tag 'RDP'. Say one species has |
|---|
| 22 | the full_names "escherichia_RDP" and "escherichia_DEW". |
|---|
| 23 | Using the tags mechanism the final field will look like this: |
|---|
| 24 | |
|---|
| 25 | ' [DEW] escherichia_DEW [RDP] escherichia_RDP' |
|---|
| 26 | |
|---|
| 27 | Tags are sourrounded by brackets and put in front of the |
|---|
| 28 | corresponding field value. If both subfields have the same |
|---|
| 29 | value (e.g. "escherichia_coli") fields get merged: |
|---|
| 30 | |
|---|
| 31 | ' [DEW,RDP] escherichia_coli' |
|---|
| 32 | |
|---|
| 33 | NOTES Operating on tags from LINK{mod_field_list.hlp} allows to modify single |
|---|
| 34 | subfields only (i.e. not touch other subfields). |
|---|
| 35 | If there are no tags used yet, the default tag will be added. |
|---|
| 36 | |
|---|
| 37 | Using LINK{mergetaggedfield.hlp} always operates on all found tags. |
|---|
| 38 | If source- or target-field does not contain tags, the specified |
|---|
| 39 | source- or target-tag will be added. |
|---|
| 40 | |

| 41 | EXAMPLES None |
|---|
| 42 | |
|---|
| 43 | BUGS Square Brackets in the fields get replaced by '{}' |
