<a name="acc"><h2>Accessing the Registry</h2></a>

The <a target="OMNAreg" href="http://www.openmobilealliance.org/tech/omna/omna-XCAP-AUID-registry.aspx">OMA-defined XCAP AUIDs</a> is an evaluation version and not presently available from <a target="OMNAmain" href="http://www.openmobilealliance.org/tech/OMNA.aspx">Open Mobile Naming Authority (OMNA)</a> which is a registry service provided by the Open Mobile Alliance.
<p>

<hr class=1>
<a name="purp"><h2>Purpose of the Registry</h2></a>

<p>
The OMA-defined XCAP AUID records specific assigned uses of vendor format AUIDs using the OMA domain prefix <nobr>("<b>org.openmobilealliance."</b>).</nobr>
These are only available for OMA Enabler defined use.
<p>

<hr class=1>
<a name="data"><h2>Data Model for the Registry</h2></a>

<p>The OMA-defined XCAP AUID is a string that conforms to the grammar defined in section 5.1 of <a href="http://www.ietf.org/rfc/rfc4825.txt">RFC 4825</a> relating to the <nobr><b>vendor-a-uid</b></nobr> entity.
<p>

<hr class=1>
<a name="how"><h2>How to Get a Registration</h2></a>

<p>
At present, only OMA Working Groups may reserve an XCAP AUID from this OMNA registry.
<p>
When an OMA Working Group needs a value from this registry they should follow these steps:

<ol>
<li>Work with the OMA PAG Working Group when they need to determine how they can use existing XCAP AUID or need to declare their own.  If they can reuse one, they would be able to reference one already in the OMNA registry.</li>
<li>If a new XCAP AUID is needed, the OMA PAG Working Group shall work with the originating working group on an appropriate token label to be used.</li>
<li>The Requesting Working Group will provide information to the DSO representative to ensure the OMNA registry is updated accordingly.</li>
</ol>
<p>

<hr class=1>
<a name="ref"><h2>Referencing an Assignment in the OMNA Registry</h2></a>

<p>
There may be times that a specification needs to reference the OMNA Registry to point people to values that are available for use.
In addition, it may make sense to point to OMNA to make it clear that an assignment being mentioned is valid.
In these cases, it will be good to have a formal reference to the OMNA information.
<p>
The current practice for OMNA references is to point to the main OMNA directory and provide information to permit a person to click to the appropriate registry.  This allows for future revisions to the registry structure or presentation as the OMNA main page will be the only page that needs to be protected.
<p>
An example usage of a reference to this registry is
<center>
<table width=65% border=1><tr><td bgcolor=FFCCCC>
...The XCAP AUID identifier that shall be used for this message is declared in OMNA XCAP AUID Registry [OMNA]...
</td></tr></table>
</center>
<p>
And an example of the reference itself is
<center>
<table border=1 width=65%><tr bgcolor=CCFFFF><td valign=top>
[OMNA]
</td><td>
Open Mobile Naming Authority,<br>URL: <font color=blue>http://www.openmobilealliance.org/tech/omna</font>
</td></tr></table>
</center>
