We realized that "embeddedTypes" are missing in the property dictonary.
Update of "linkedTypes" following changes to the schemas seems to be not tracked correctly (e.g. "hash" for schemas "fileBundle"/"fileInstance"/"fileRepository": changed from "_linkedTypes" to "_embeddedTypes" but still listed as "linkedTypes" in properties; EDIT: This has been fixed suddenly somehow...)
Going through the vocab (properties.json) I realized some weird things in the vocab extraction:
"deprecated": true
but it should have been false"deprecated": "description of the property"
+"description": null
I will have a look at the script and see if I can find where such errors may occur from. If I find something I'll provide more details.
