<h2>Introduction</h2> |
| 66 |
|
| 67 |
<p>Recently, a number of auto-discovery conventions |
| 68 |
are proposed and implemented in various Web browsers |
| 69 |
and so-called <q>Web 2.0</q> services. They provide |
| 70 |
means to extract links to resources (or other useful |
| 71 |
information) from Web documents in somewhat reliable |
| 72 |
ways. However, the syntax of these techniques |
| 73 |
vary and the implementators have to add specific |
| 74 |
code for each auto-discovery technique.</p> |
| 75 |
|
| 76 |
<p>The <dfn id="DT-autodiscovery-autodiscovery">Auto-Discovery |
| 77 |
Auto-Discovery</dfn> is a mechanism to discover |
| 78 |
auto-discovery element that contains links (or |
| 79 |
other information) for auto-discovery techniques. |
| 80 |
With the Auto-Discovery Auto-Discovery, user agents |
| 81 |
can detect auto-discovery elements without any |
| 82 |
particular knowledge to a specific auto-discovery |
| 83 |
technique.</p> |
