Forms Examples

As the first stage of the microformats process, this page collects examples of best/common practice for annotating HTML form to describe input data.

The Problem

The vast majority of websites use some kind of forms to receive input -- far more than provide any kind of web services. Currently, people who want to call into those websites need to manually screen-scape and generate urlencoded, or (worse) MIME multipart.

The purpose of this exploration is to determine if there is any consistent design patterns used by forms and/or semantic tagging that would allow automatic extraction of the information needed to generate HTML input.

Existing Practices

(first guess)

• Everybody seems to use tables, not labels
• Common tags are:
  • label: for
  • form: name, method, action
  • input: type, name, maxlength, value
  • select: name, onChange
  • option: value

Proposal

• Best design pattern so far:

<li><label for=...>

<input type=... name=... value=... ...>

</label></li>

• Why so much type=hidden?
