About standards especially in W3C, there is a related "paper" that followed Simple DDR by about 2 years, but especially with tips like "prefer server-side recognition over client-side recognition" also explicitely refers to DDR: http://www.w3.org/TR/2010/REC-mwabp-20101214/
Everyone goes crazy about W3C recommendations like HTML5, CSS3 or WebSockets, I'm sure some of you at least heard about them or used them somewhere. However all of them are "Candidates" so they are not "Final" (as DDR Simple went in late 2008) so everyone implementing against them practically is on a "moving ship" and some of its cargo might even be dropped before it goes final. W3C among other standard bodies has extremely long development cycles. So a standard or recommendation (they all are by definition) finalized 6 years ago merely can be considered "juvenile" by its practice, while WebSockets, etc. aren't even born yet, they are still "fetal"[?] Wikimedia also uses or supprts the W3C DDR option (Bertrand should know more) and both it http://en.wikipedia.org/wiki/Device_Description_Repository or Mozilla: https://wiki.mozilla.org/Compatibility/UADetectionLibraries acknowledge systems like OpenDDR are compatible and detect its browsers well [?] In the list and slides we may have forgot at least one other large vendor, DetectRight, and they also are big in W3C: http://www.detectright.com/w3c_compatibility.html (there could be alternate ways of accessing its data, but W3C DDR compliant is fairly popular and not "academic", just look at all the large customers, I know first hand, BT uses it, we also helped them with their booking system once) Werner
