The system adds a namespace identifier to the front of application artifacts such as
tables, scripts, and configuration records.

The identifier cannot be changed or removed from application artifacts to ensure that they are
always associated to the proper application and that they have a unique name.

The system generates a namespace identifier from the following information:  
{#c_NamespaceIdentifier__table_sxb_nnb_br__entry__3}

| Element | Requirements | Sample Value |
|-|-|-|
| The prefix characters for a scoped application. | Scoped applications always start with an x_ prefix. | x_ |
| The instance customer prefix (glide.appcreator.company.code) | This string is two to five characters long. ServiceNow generates this prefix for each customer. The instance stores the prefix in the glide.appcreator.company.code system property. | acme |
| The application ID | This string can be up to 40 characters long. If the string is longer than 18 characters, the system truncates the application name and appends it to prefix <kbd class="ph userinput">x_&lt;glide.appcreator.company.code&gt;_</kbd>. Application developers set this ID when they create the application. The system uses the application name by default. | book_rooms |
[Table 1. Elements used to generate a namespace identifier]

{#c_NamespaceIdentifier__table_sxb_nnb_br}

The example values generate a namespace identifier of x_acme_book_rooms.
