Google, Facebook and others are asking websites to put simple annotations (e.g. RDFa) on web pages. Turns out there are other unexpected reasons why this can bring value and customers.

We will begin by showing in practice what these annotations are, what direct benefits they bring and certain advanced tools to explore and validate them.

We will then show how said annotations further enable the "import of value" from the rest of the "Web of Data" to gain recommendations, information boxes, and custom faceted browsers based on relevant data your website/database never had directly.

We will also show how, as you do this, your site becomes itself a datasource which can be used in other people's mashups and as such be rewarded with visitors, recognition and possibly direct revenues.

• Lightweight web markup: basics, common uses, direct benefits
• Getting recommendations, information boxes and more leveraging the rest of the Web of Data (and your simple web page markup)
• Providing widgets with the content of your site to others
• Your pages as a dataset for others to integrate: get visitors and value
• Case Studies: ecommerce and multimedia content annotations
• Hands on example, creating your own company semantic embeddable widget
