Hi Thierry,

I've discussed the impact of the changes on the implementation with Martin and Florian. Here are our conclusions:

- The DC Copyright issue is the only one in DC that touches a required property. The JSON is correct, although but the value should be split in the RDF file (or assigned to copyrightedBy instead of copyrightHolder). As the implementation starts from the DC file, this does not impact the implementation.

- The YT issue with keyframe is an error in the JSON file (two strings put into one), the correct string is thus contained in the one returned (which obviously was used for checking the result). Correcting this does not impact the implementation report.

- The Date issues in both formats concern optionally returning the type of the date (creationDate). As this is optional, the test would still be passed if an implementation does not return the optional attribute.

- The same holds for the rating system type in YT.

- Location (in both formats) seems to be the most critical, as the correct JSON contains 0 for values not-existing in the source data. As the attribute is optional, omitting it in the response returned from the implementation would still result in a passed test, however not the case when it is returned with 0, when it is deleted from the JSON. While we think it would be cleaner to drop the attribute in cases where no value is there (as "0" IS somewhere), on could argue that the integer 0 is not a valid deg/min/sec nor floating point value, and thus is interpreted as undefined. This would avoid changes to the implementation. The alternative could be to introduce a weaker notion of passed for this case, that only concerns the mandatory attributes.

Best regards,
Werner
