Minor JSON-LD glitches

[kurzum]

I LD'ed into

curl "https://databus.dbpedia.org/dbpedia/generic/infobox-properties/2022.03.01" -H "Accept: application/ld+json" 

and found some json-ld hickups. byteSize and contentVariant are in context, but get serialized with prefixes. dataid dataset is not in json-ld

"@type": [
            "Version",
            "http://dataid.dbpedia.org/ns/core#Dataset"
         ],

"dcat:byteSize": 882435565,

 "subPropertyOf": "databus:contentVariant"

also there is a variation between issued and modified.

"issued": "2022-03-01T00:00:00Z",
 "modified": "2023-06-26T12:48:48.630Z",
