Dear Thierry, all,
as announced in my last email, here are my comments regarding the JSON youtube result set:
MADate:
JSON:
{ "MADate" : {
"propertyName" : "date",
"value" : "2010-01-26T10:00:00Z",
"sourceFormat" : "yt",
"mappingType" : "exact",
"date" : "2010-01-26T10:00:00Z",
"statusCode" : 200
}
RDF:
<ma:creationDate rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">
2010-01-26T10:00:00Z
</ma:creationDate>
Optional typeLabel attribute "creation date" missing JSON, although related information available in RDF.
Location:
JSON:
{ "Location" : {
"propertyName" : "location",
"value" : "35.669998 139.770004",
"sourceFormat" : "yt",
"mappingType" : "exact",
"longitude" : 35.669998,
"latitude" : 139.770004,
"altitude" : 0,
"statusCode" : 200
}
RDF:
<ma:Location>
<ma:locationLongitude rdf:datatype="http://www.w3.org/2001/XMLSchema#decimal">
35.669998
</ma:locationLongitude>
<ma:locationLatitude rdf:datatype="http://www.w3.org/2001/XMLSchema#decimal">
139.770004
</ma:locationLatitude>
</ma:Location>
No altitude data available in RDF, however altitude in JSON is set to zero.
Keyword:
JSON:
{ "Keyword" : {
"propertyName" : "keyword",
"value" : "SM ENTERTAINMENT Oh!",
"sourceFormat" : "yt",
"mappingType" : "exact",
"keywordLabel" : "SM ENTERTAINMENT Oh!",
"statusCode" : 200
}
},
RDF:
<ma:hasKeyword rdf:parseType="Resource">
<rdfs:label>
SM ENTERTAINMENT
</rdfs:label>
</ma:hasKeyword>
<ma:hasKeyword rdf:parseType="Resource">
<rdfs:label>
Oh!
</rdfs:label>
</ma:hasKeyword>
JSON Keyword "SM ENTERTAINMENT Oh!" is concation of 2 different keywords in RDF.
Seems to be a minor issue regarding the implementation report, since the JSON result sets for 3 remaining keywords have been returned correctly.
Rating:
JSON:
{ "Rating" : {
"propertyName" : "rating",
"value" : "4.6510544",
"sourceFormat" : "yt",
"ratingValue" : 4.6510544,
"minimum" : 1,
"maximum" : 5,
"statusCode" : 200
}
},
<ma:hasRatingSystem rdf:parseType="Resource">
<rdfs:label>
higherBetter
</rdfs:label>
</ma:hasRatingSystem>
Optional attribute ratingSystemLabel is not present in JSON result set, required data would be available in RDF.
