Parsing

Jump to: navigation, search


This is a braindump, this page will need cleaning-up, take everything with a grain of salt at the moment.

For now, start with reading hcard-parsing as that has more detail and has been more throughly reviewed and implemented.

Contents

By Element

This is a matrix of element and type. This should be describe under what circumstances each value and where that value comes from. The list of elements has been taken from http://www.w3.org/TR/html4/index/elements.html with some HTML5 elements added, in particular those with special parsing needs.

See semantic html for a definitive list of elements.

data types

(this probably needs a better name) There are two types in microformats, protocol types and strings. Strings could be integers, such as ratings, strings, such as a note, or datetimes, such as dtstart. Protocol types are UIDs, URLs, email addresses, (sometimes Telephones and faxes)

If there is a comma list, then this is in order of availability. For instance, the ABBR element is @title,node-value. IF the @title is present then it is used, if not the stack is popped and node-value is looked at, if there is no node-value, then the value is NULL.

New Elements

When a new semantic HTML element is introduced, follow these steps to update microformats to handle the new element.

  1. add the element to SemanticHTML MediaWiki extension, which enables creating wiki live markup examples
  2. update parsing rules accordingly (on parsing and hcard-parsing wiki pages)
  3. create/iterate actual live markup examples on wiki with real world content examples
  4. implement experimental new parsing support, test on wiki examples. optionally deploy for broader testing (e.g. dev.)
  5. if results are as expected/predicted, create test case from example markup with results as expected. if not then re-assess how parsing should work and go to 2.
  6. add parsing support to additional implementations
  7. have individual implementations test/deploy broadly as they see fit
