You need to add your GPG keys in https://svn.apache.org/repos/asf/onami/committers/KEYS before a release. Here are some useful GnuPG commands to generate your Keys.
$ gpg --gen-key gpg (GnuPG) 1.4.11; Copyright (C) 2010 Free Software Foundation, Inc. This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. Please select what kind of key you want: (1) RSA and RSA (default) (2) DSA and Elgamal (3) DSA (sign only) (4) RSA (sign only) Your selection? 1 DSA keypair will have 1024 bits. ELG-E keys may be between 1024 and 4096 bits long. What keysize do you want? (2048) 2048 Requested keysize is 2048 bits Please specify how long the key should be valid. 0 = key does not expire <n> = key expires in n days <n>w = key expires in n weeks <n>m = key expires in n months <n>y = key expires in n years Key is valid for? (0) 0 Key does not expire at all Is this correct? (y/N) y You need a user ID to identify your key; the software constructs the user ID from the Real Name, Comment and Email Address in this form: "Heinrich Heine (Der Dichter) <heinrichh@duesseldorf.de" Real name: Simone Tripodi Email address: simonetripodi@apache.org Comment: simonetripodi You selected this USER-ID: "Simone Tripodi (simonetripodi) <simonetripodi@apache.org>" Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O You need a Passphrase to protect your secret key. You don't want a passphrase - this is probably a *bad* idea! I will do it anyway. You can change your passphrase at any time, using this program with the option "--edit-key". We need to generate a lot of random bytes. It is a good idea to perform some other action (type on the keyboard, move the mouse, utilize the disks) during the prime generation; this gives the random number generator a better chance to gain enough entropy. ++++++++++++++++++++.++++++++++..+++++++++++++++++++++++++++++++++++++++++++++++ +++.+++++++++++++++.++++++++++++++++++++..+++++++++++++++>++++++++++............ .........................+++++ We need to generate a lot of random bytes.

You need to append this result to https://svn.apache.org/repos/asf/onami/committers/KEYS.
A quick way to append this result would be executing the command below:
(gpg --list-sigs <your key> && gpg --armor --export <your key>) >> KEYS
You also need to upload your key to the public server: http://pgp.mit.edu/ by copying the same you appended in the text field and submit. You can ensure by searching your email in key search engine.
