Dear Chris, please find my comments inline :) Best, Florian Am 23.02.2010 um 15:11 schrieb Chris Poppe: > Dear all, > > thanks for the update and revision of the data types.

Yes, thatīs right, there might be more vocabularies. Perhaps we can suggest a big vocabulary, like the EBU one, but let it open for other vocabularies. > Dominique has sent an email with remarks on the API document > (2/18/2010: Comments on API for Media Resource 1.0) stating that for > the duration property milliseconds are preferred over seconds. From my point of view, the datatype doesn't belong to a particular unit, like second. I only wanted to show with the example, that seconds, milliseconds and so on can be specified. This is only a definition thing. Neither does our definition in the document say what time unit has to be used - perhaps something to update (just like the keyword definition)? > Additionally, the types for description and namedFragments which we > discussed today but did not make it into the minutes map exactly to > what you suggest :) Woohoo :) > Kind regards, > Chris > > > Quoting "Florian Stegmaier" <stegmai@dimis.fim.uni-passau.de>: > >> Dear all, >> >> in a seperate Skype session after the first meeting day of the 6th >> F2F, Werner, Tobias and i went through the meeting minutes [1] and >> discussed the defined datatypes of the properties. >> >> Here is our consensus: >> >> ###Identification### >> ma:identifier ::: URI (maybe with subproperties: [identifier:URI, >> type:String]) >> ma:title ::: [title:String, type:String] >> ma:language ::: String (controlled by BCP 47 [2]) >> ma:locator ::: URI >> >> ###Creation### >> ma:contributor ::: [Identifier:String or URI, role:String] >> ma:creator ::: [Identifier:String or URI, role:String] >> ma:createDate ::: [Identifier:Date, role:String] >> ma:location ::: [Name:String] or [longitude:Float,latitude:Float, >> alitude:Float] >> >> ###Content description### >> ma:description ::: String >> ma:keyword ::: String (here we want to change the >> definition...keyword should be only keyword - but maybe more tokens >> -> more keywords accordingly more elements) >> ma:genre ::: String (controlled, e.g., by the EBU vocabulary) >> ma:rating ::: [Identifier:URI, >> value:Float,max:Float,min:Float,context:String] >> >> ###Relational### >> ma:relation ::: [Identifier:URI, relation:String] >> ma:collection ::: String or URI (nothing complex here) >> >> ###Rights### >> ma:copyright ::: [copyright:String, Identifier:URI] >> ma:licence ::: [licence:String, Identifier:URI] >> >> ###Distribution### >> ma:publisher ::: String or URI (no role/subproperties needed here) >> ma:targetAudience ::: [Identifier:URI, classification:String] >> >> ###Fragments### >> ma:fragments ::: [Identifier: URI, role: String] >> ma:namedFragments ::: [label: String, identifier: URI] >> >> ###Technical properties### >> ma:frameSize ::: [width:Float, height:Float] >> ma:compression ::: String (controlled by RFC 4281 [3]) >> ma:duration ::: Float (e.g., 5.001 -> 5s and 1ms) >> ma:format ::: String (controlled by MIME types [4]) >> ma:samplingrate ::: Float >> ma:framerate ::: Float >> ma:bitrate ::: Float >> ma:numTracks ::: Integer >> >> In the F2F (or maybe only in the minutes) there was no definition >> of ma:description and ma:namedFragments. >> >> Best, >> Florian, Werner and Tobias >> >> [1] http://www.w3.org/2010/02/23-mediaann-minutes.html >> [2] http://www.rfc-editor.org/rfc/bcp/bcp47.txt >> [3] http://www.ietf.org/rfc/rfc4281.txt >> [4] http://www.isi.edu/in-notes/rfc2046.txt >> _____________________________ >> Dipl.
