I've mentioned a few times recently that we're working towards using microformats / structured-blogging to allow users to represent special kinds of content within their knotes weblog entries. There are many reasons for taking this route: it allows users to see content-creation as more homogeneous and spontaneous; it represents special content structure in interoperable machine-readable formats; it allows us to generalise the notion of special content types from the point of view of knotes' own interfaces and leave the details to special-type plugins...

The first few special structurings we'll be looking at are: event, google-video clip and embedded RSS, after which we'll be looking at variants on review. See my earlier post in elearning2.0 for a sketch of the merits of embedding live RSS to augment a blog entry (eg as reference list or background-resource links ). See this post in the work-related learning blog for an illustration of embedding google-video content in blog content. Event as a structured-blogging type should be pretty obvious: roughly, it takes the place of the Plone 'Event' content type allowing users to denote upcoming events in an ad-hoc but machine-readable way so that they integrate with portal calendar and can be aggregated into iCal syndication.

Events as microformats embedded in the blog content have the additional advantage that 3rd party harvesters can discover the event-wise information directly from the rendered html / rdf of the blog entry.

Steve has the Event microformat type working in a test installation now. Another few days should see tests within our main knotes production version. Other special types should be coming thick and fast after that, some of them for very special uses such as within learners' eportfolios, some of more general use. Exciting developments!
