I'm integrating a legacy system with SP2010 using a literal SOAP calls. I can do a call such as CopyIntoItems or UpdateListItems and doing so, set metadata fields by providing a Fields node such as:

```
  <Fields>
       <FieldInformation Type="Note" DisplayName="Country_0"
                         Id="de1e6424-7a8a-42a5-8d21-73402fe2e609"
                         Value="UK|91c89925-16e6-4d41-9e71-ec45e8f2a113" />
       ...
  </Fields>

```

In the Value attribute, I have to give the guid of the taxonomy or metadata term. That works fine in the above example since I happen to know the guid of the term UK. However, how can I dynamically figure out what the guid of some other value, say France for example, would be? I was thinking of making a utility to get them all and cache them on my system somehow so I can look them up easily, but where are they defined?

Possibly a stupid question, I get the feeling I've missed something...
