  - getModel
```
UcumModel getModel()
```
    provided for various utility/QA uses. Should not be used for general use
    
    Returns:

  - ucumIdentification
```
UcumService.UcumVersionDetails ucumIdentification()
```
    return Ucum Identification details for the version in use
  - validateUCUM
```
List<String> validateUCUM()
```
    Check UCUM. Note that this stands as a test of the service more than UCUM itself (for version 1.7, there are no known semantic errors in UCUM). But you should always run this test at least once with the version of UCUM you are using to ensure that the service implementation correctly understands the UCUM data to which it is bound
    
    Returns:
    
    a list of internal errors in the UCUM spec.

```
    Search through the UCUM concepts for any concept containing matching text. Search will be limited to the kind of concept defined by kind, or all if kind is null
