Did you ever wanted to increase the usability of your data for both humans and spiders? A new set of formats called "microformats" improve the structureness of data for calendar and vcard entries.
phpMicroformats helps you to generate this structured data easily and so to improve the spiders to understand your data.
About Microformats
Microformats are specific
enriched html structures that both helps humans and computers to
understand the content. There exists already formats for calendar events called
hCalendar - based on vCalendar format - and vcards - based on vCard
format - and more are developed and standardized at the moment.
The advantage of using microformats is that it is easier for humans to
understand - but also for computers to interpret and understand. Since it
is using wildly accepted standards as (x)html enriched with some
specific but limited (CSS) classes, it can be implemented easily.
