WIF in a nutshell[edit]

WIF is the lowest common denominator of wiki content exchange. WIF defines a subset of XHTML as an over-the-wire format for wiki content exchange. A WIF API is supposed to extract WIF from a wiki and be able to insert WIF in the desired wiki syntax back into the wiki.

 structure:       <html>, <head>, <title>, <body>

 headlines:       <h1>, <h2>, <h3>, <h4>, <h5>, <h6>

 block elements:  <p>, <pre>, <hr> 

 lists:           <dl>, <dd>, <dt>, <ol>, <ul>, <li>

 tables:          <table>, <tr>, <th>, <td>

 inline elements: <i>, <b>, <sub>, <sup>, <tt> --> consider using <em>, <strong>, <sub>, <sup>, <code>

 images:          <img> with attribute ’src’, 

 links:           <a> with attribute ’href’

All other elements and attributes are excluded from WIF, which means WIF importers are not required (but allowed) to handle them. They are supposed to ignore all unknown tags.

At the WikiSym 2005 in San Diego, a Wiki Standardisation Request for a Wiki Interchange Format was started. Max became the spec lead of the WSR3. Many people have contributed since then. There was an open space session dedicated to WIF at the WikiSym2006.
