#### Nested meta properties
|
||||
|
||||
If your meta section has nested properties and looks like this:
|
||||
|
||||
```yaml
|
||||
meta:
|
||||
data_governance:
|
||||
team_owner: "Finance"
|
||||
```
|
||||
|
||||
and you want attach term Finance_test in case of data_governance.team_owner is set to Finance, you can use the following meta_mapping section:
|
||||
|
||||
```yaml
|
||||
meta_mapping:
|
||||
data_governance.team_owner:
|
||||
match: "Finance"
|
||||
operation: "add_term"
|
||||
config:
|
||||
term: "Finance_test"
|
||||
```
|
||||
|
||||
Note: nested meta properties mapping is supported also for column_meta_mapping
|
||||

||||
#### Stripping out leading @ sign
|
||||
|
||||
You can also match specific groups within the value to extract subsets of the matched value. e.g. if you have a meta section that looks like this:
