- HM Government = Her Majesty‘s Government (I‘m afraid we British only have one if the Queen chooses!) Prof. Dr. Max Mustermann | Musterfakultät
- Brand = Top Gear Series = Top Gear Season 5 Episode = Top Gear Season 5 Episode 2 They‘re all Programmes because they‘re all programmed (scheduled) onto a Service (e.g. BBC 1, which has an outlet BBC 1 North over a channel like Digital Satellite) A Broadcast is the actual event associated with a Version – Episodes are available in different versions because they can be shortened and/or have added subtitles, sign language, audio descriptions, etc. Prof. Dr. Max Mustermann | Musterfakultät
- Implicit knowledge – if you call a service with input ‚Vienna‘ and get output ‚20C‘, the implicit knowledge is that 20C is the temperature at the last report in Vienna (+ provenenance = ‚ according to ...‘) Prof. Dr. Max Mustermann | Musterfakultät
- The upper right is standard application of Linked Data principles – if you request (state, in the request header, that you accept) HTML, you are redirected to a ‚page‘ URI; if you request RDF, you are redirected to a ‚data‘ URI (i.e. page/data is, in our implementation, appended to the end of the resource‘s URI). This is because the original URI actually identifies the airport but, since the airport is a real thing, not an information resource, you can‘t actually retrieve it in itself, only a related information resource. The bottom right is how we extend in LOS – under the same URI scheme you can ask for a computation relative to the resource by POSTing to a URI representing the weather under it (the airport).
