Our concerns were:They're looking at using RDFa, which they describe as 'a slightly bigger S semantic web technology similar to microformats but without some of the more unexpected side-effects'.
Until these issues are resolved the BBC semantic markup standards have been updated to prevent the use of non-human-readable text in abbreviations.
- the effect on blind users using screen readers with abbreviation expansion turned on where abbreviations designed for machines would be read out
- the effect on partially sighted users using screen readers where tool tips of abbreviations designed for machines would be read out
- the effect of incomprehensible tooltips on users with cognitive disabilities
- the potential fencing off of abbreviations to domains that need them
Their support for RDFa is timely in light of Lee Iverson's presentation at the UK Museums on the Web conference (my notes). It's also an interesting study of what can happen when geek enthusiasm meets existing real world users.
More generally, does the fact that an organisation as big as the BBC hasn't yet produced an API mean that creating an API is not a simple task, or that the organisational issues are bigger than the technical issues?
