Re: [backstage] space and time in backstage

[Duncan Barclay]

Hi, >From my experience using the BBC feeds, they don't seem to mind the feeds being cached, so long as if you output them, they aren't too out of date (don't want people thinking the BBC are slow at picking up news stories now do we? :) ).  Updating about every 15 to 30 mins seems to work quite well. I assume the conflict you are talking about is referring to this: "2.4 You must create a functional link back to the BBC News story(ies) summarised by the BBC Content . You may not directly or indirectly change, edit, add to or produce summaries of the BBC Content or any content on the BBC website nor place any full-story BBC content in an HTML frame-set." My interpretation of it is that you can output the summary of the stories provided in the RSS feed, but you aren't allowed to make your own summaries by scraping the site for the content. There are a couple of projects that use time rather than space, including http://www.solutionseven.co.uk/bbc/default.aspx?y=2005&m=6&d=1 by Richard Astbury (which seems to have stopped updating), and my one, http://backstage.min-data.co.uk/topstories/ .

I wonder if anyone has thought of mixing in temporal analysis into this, or doing some sort of temporal analysis with no spacial stuff at all. For example, with traffic reports, imagine a map that accumulated information over time and then coloured the accident hotspots in some meaningful way - same for news and locations and even weather! Such a system would, of course, require more state, but I think it is an area worth considering... Its an interesting idea , i'm imagining that to derive the temporal state data you would need to store a copy of the feeds localy (server) to avoid slaughtering the bbc feed servers on each page load . What is the bbc position on caching the data ? In pedant mode i can see a possible conflict with section 2.4 of the RSS licence where it prohibits the production of summaries. Toodle-pip Amias
