#  `stardog namespace import` 
## Description
Imports namespace prefixes from an RDF file.
## Usage
`stardog [ --krb5 ] [ --krb5-disable-rdns ] namespace  import [ {-p | --passwd} <password> ] [ {-P | --ask-password} ] [ --run-as <username> ] [ --token <token> ] [ {-u | --username} <username> ] [ {-v | --verbose} ] [--] <database> <file>...`
{: .fs-5}
## Options

Name, shorthand | Description 
---|---
`--krb5` | Use the Kerberos environment.
`--krb5-disable-rdns` | Disable reverse DNS lookup for Kerberos clients.
`-p <password>, --passwd <password>` | Password.
`-P, --ask-password` | Prompt for password.
`--run-as <username>` | User to impersonate when running the command
`--token <token>` | Stardog JWT token
`-u <username>, --username <username>` | User name.
`-v, --verbose` | Flag that can cause more detailed information to be printed such as errors and status. Exact output depends upon the command and options used.
`--` | This option can be used to separate command-line options from the list of argument(s). (Useful when an argument might be mistaken for a command-line option)
`<database> <file>` | The name of the database or the full connection string of the database to connect to. If only the name is provided, the default server URL will be prepended to the name of the database in order to construct the connection string. Connection parameters such as ';reasoning=true' can be included in the provided database name. Connection parameters specified like this can be overridden by specific options on the command. The default server URL will be read from the JVM argument 'stardog.default.cli.server'. If the JVM argument is not set, the default value 'http://localhost:5820' is used. If the server URL has no explicit port value, the default port value '5820' is used.  To use a secure connection, you should specify the full connection string and postfix 's' to the protocol, e.g. https. The subsequent argument is an RDF file.

## Discussion
Imports namespace prefixes from an RDF file that contains prefix declarations into the database, overriding any previous mappings for those prefixes. Only the prefix declarations in the file are processed, the rest of the file is not parsed.
