1. The Civil Twilight data for a place can be used to model a daily schedule.  Here is the Bristol (City of) example:
Back on the Summer Solstice (~ Jun 21) there were over 16 hours of Civil Twilight and Daytime (1092 min.).  Today there are 571 minutes, or about 9.5 hours.  A sustainable activity schedule requires ~8 hours of sleep.  Nowhere on Earth is that possible in daylight year round.

2. An example of the XHTML/dct:bibliographicCitation is at http://www.rustprivacy.org/2011/phase/gld/cd/gld-cd.br.html
This is essentially an HTML collection of RDF/HTML citations.  The citations can be used for any XML or text actually and this fills the gap between real manifestations of concepts and virtual "manifestations" in Libraries.  For example, The Roman Empire exists only in the Library (anymore), and Lilliput,Erewhon,Shangra-la, etc. never existed anywhere else but a Library.  It's a data gap one would not expect Commerce, Governments, the EU or the UN to fill.

Hi Jeremy,


This is related to the issue I raised last week[1].  I think HTML5 breaks GRDDL, which is not "just" a syntax problem.  I have some doubts that HTML5 will meld well with scientific data.

FWIW, XHTML 1.1 has a driver for XHTML+RDFa[2].  And I am putting together an XHTML+dct:bibliographicCitation XSD Schema[3].  In the US, the Weather - DWML/XML - is already DOM'ed and it is more work to make RDFa microlinks than it is to write custom Transforms to display formats.  I did add Civil Twilight to the DWML and produced a "Data Available" page.  The data validates with XSD Schema.  You might like to have a look[4] (has not been updated in ~ month, since TPAC). 
Adding sunrise/sunset or Civil Twilight data to the weather data is something the BBC should consider.  Unfortunately the UK is without benefit of insane politicians who consider only "work for wages" work.  This is a Health and Labor issue, since travel to and from work for wages is a higher risk with fatigue and darkness[eg. 5].  I have some corrections to these pages, but you'll get the idea.

RDFa and HTML5 
Hi, I work with the BBC’s Weather web team and we’d like to add some minimal RDFa to forecast pages to link them with their corresponding Geonames ID.  

The BBC URLs make use of GeoIDs, but there’s nothing that explicitly states (for example):
    http://www.bbc.co.uk/weather/2637142 – is_a_forecast_for - http://sws.geonames.org/2637142

Back in August on this list Keith Alexander suggested something like:
    <link rev="meteo:forecastPage"  href="http://sws.geonames.org/2637142/"> 

which seems ideal, but unfortunately when I tried this on a sandbox it failed validation – apparently <linl rev=””> has been deprecated in HTML5. 

Has anyone come up against a similar problem, or have a suggestion for how else we might make this association?
