Martin,

I would like to focus first on the DC and Youtube formats as these are 
the 2 formats we use for the implementation report.

But indeed we should fix the other formats and have the JSON responses 
in Synch.

I am not sure I understand all the issue raised.

See my responses in line ...

Not sure what the issue is. Both seem to have 2 occurences:
the EBUCore XML
http://www.w3.org/2008/WebVideo/Annotations/drafts/metadata_formats/EBUCoreXML_ITM528229_extended.xml
...
<coverage><spatial><location 
typeLink="cptype:city"><name>CARACAS</name></location><location 
typeLink="cptype:country"><name>VENEZUELA</name><code>country:VE</code></location></spatial></coverage>
...
and the JSON
...
{ "Location" : {
     "propertyName" : "location",
     "value" : "CARACAS",
     "language" : "English",
     "sourceFormat" : "ebucore",
     "mappingType" : "exact",
     "locationLabel" : "CARACAS",
     "longitude" : 0,
     "latitude" : 0,
     "altitude" : 0,
     "statusCode" : 200
     }
   },
   { "Location" : {
     "propertyName" : "location",
     "value" : "VENEZUELA",
     "language" : "English",
     "sourceFormat" : "ebucore",
     "mappingType" : "exact",
     "locationLabel" : "VENEZUELA",
     "longitude" : 0,
     "latitude" : 0,
     "altitude" : 0,
     "statusCode" : 200
     }
   },
...


> NamedFragment - NamedFragements in JSON, however no ma:hasNamedFragment relations in ontology

the EBUCore XML
http://www.w3.org/2008/WebVideo/Annotations/drafts/metadata_formats/EBUCoreXML_ITM528229_extended.xml

in the Ontlogy exact mapping from
namedFragment 	to	hasPart






> Locator - property has been mixed up with Location, contains the same data
>
> Exif:
> FrameSize -  JSON contains 2 FrameSize data sets for same media resource, one FrameSize should refer to related thumbnail image

Right the second relates to the thumbnail.


>
> ID3:
> Contributor - roleLabels for Contributor (e.g. "TCOM Composer") not present in ontology
>
> LOM 2.1:
> FrameSize - present in JSON, no data available in ontology
> Duration - same issue


Not sure what the issue is:

ma:frameSize 	more general mapping to	"size"

lom example:
...
<technical><size>1000</size>
...

lom Json:

   { "FrameSize" : {
     "propertyName" : "frameSize",
     "value" : "1000",
     "language" : "English",
     "sourceFormat" : "lom21",
     "mappingType" : "more general",
     "width" : 0,
     "height" : 0,
     "statusCode" : 200
     }
   },


ma:duration  is exact mapping to duration

there seems to be a bug here in the Lom example: the duration is in a 
comment:
...
<!--duration><duration>1H</duration>
   </duration-->
...

Lom Json:

The duration value set to zero seems wrong (should be one hour)

  { "Duration" : {
     "propertyName" : "duration",
     "language" : "English",
     "sourceFormat" : "lom21",
     "fragmentIdentifier" : "exact",
     "duration" : 0,
     "statusCode" : 204
     }
   },

>
> Media RSS:
> Copyright - holderLink present in JSON, no information available in ontology

Not sure what the issue is:

ma:copyright 	exact mapping to 
"rss/channel/item/media:content/media:copyright"


MediaRSS example:
...
<media:copyright url="http://blah.com/additional-info.html">2005 FooBar 
Media</media:copyright>
...

MediaRSS Json:
...
   { "Copyright" : {
     "propertyName" : "copyright",
     "value" : "2005 FooBar Media",
     "language" : "en",
     "sourceFormat" : "mrss",
     "mappingType" : "exact",
     "copyrightLabel" : "2005 FooBar Media",
     "holderLink" : "http://blah.com/additional-info.html",
     "statusCode" : 200
     }
...
>
> TV-Anytime:
> TargetAudience - multiple targetAudience result sets present in JSON, only 1 target audience in ontology

Not sure what the issue is:

ma:targetAudience 	related mapping to "Genre"

TVA  example:

...
<Genre href="urn:tva:metadata:cs:ContentCS:2005:3.1.1.1"><Name>Daily 
news</Name></Genre><Genre 
href="urn:tva:metadata:cs:ContentCS:2005:3.1.1.13"><Name>Weather 
forecasts</Name></Genre><Genre 
href="urn:tva:metadata:cs:FormatCS:2005:2.1.1"><Name>Bulletin</Name></Genre><Genre 
href="urn:tva:metadata:cs:IntentionCS:2005:1.2"><Name>INFORM</Name></Genre><Genre 
href="urn:tva:metadata:cs:ContentCS:2005:3.1.1.9"><Name>Sports</Name></Genre>
...

TVA  Json:
...
{ "TargetAudience" : {
     "propertyName" : "targetAudience",
     "value" : "Weather forecasts",
     "language" : "EN-UK",
     "sourceFormat" : "tva",
     "mappingType" : "related",
     "audienceLink" : "urn:tva:metadata:cs:ContentCS:2005:3.1.1.13",
     "audienceLabel" : "Weather forecasts",
     "statusCode" : 200
     }
   },
   { "TargetAudience" : {
     "propertyName" : "targetAudience",
     "value" : "Bulletin",
     "language" : "EN-UK",
     "sourceFormat" : "tva",
     "mappingType" : "related",
     "audienceLink" : "urn:tva:metadata:cs:FormatCS:2005:2.1.1",
     "audienceLabel" : "Bulletin",
     "statusCode" : 200
     }
