Case Sensitivity {#tms-case-sensitivity}
========================================

Token IDs are not case sensitive. The following requests return the same resource:

```
GET /instrumentidentifiers/49C26351BF7D8765E05333B9d30AA9DB
```

```
GET /instrumentidentifiers/49c26351bf7d8765e05333b9d30aa9db
```

IMPORTANT Unlike the token ID in the request URL, all request fields are case sensitive.  
List matching rules:

* Accept any case (web, WEB, WeB).
* Store the expected case (WEB).
* Return the expected case (WEB) metadata.
