| The <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span> package creates instances of | |
| form data description objects. These objects instances have | |
| a simple set of methods to validate and control data | |
| as typically posted by HTML forms, | |
| thus data represented as the map of form variables | |
| to their values. In Rivet this association can be obtained either | |
| calling <a class="xref" href="load_response.html" title="load_response">load_response</a> or | |
| <a class="xref" href="var.html" title="var">var, </a> (form variables can be selectively | |
| read also calling <span style="font-family:monospace"><span class="command"><strong>::rivet::var_post</strong></span></span> or | |
| <span style="font-family:monospace"><span class="command"><strong>::rivet::var_qs</strong></span></span>) | |

| The <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span> package is still experimental. | |
| Basic functionalities and interface are not likely to change but | |
| internal details and implementation could be redesigned | |
| in future releases. More specifically the external validator mechanism | |
| will likely need design improvements. | |
