Error message #1

Hello,

first very thank indeed for this utility, it's astounding!

I run the tool in UCO 0.4 and a small JSON-LD file and it raised a short list of errors that I don't understand how to fix: Data Error: Class malformed case data: BNode <_:N3e031842e091475aa5b45555307f3331> has no datatypes. Data Error: N174ffae3fd074a06b49239526daf3c56 has no ranges. Constraint Error: Class Property property has 2 values but must have at most 1.

and a few more similar to the above ones. The last error is disorienting because I have other uco-core:Relationship objects with similar value for the property uco-core:kindOfRelationship.

I can provide the JSON-LD file in case of need.

Best regards

The BNode error is a bug in the program. The Validator does not support ordered lists (oso:slots and olo:items), and their BNodes confuse the tool. The next release, Version 1.1, will still not support ordered lists. Please be patient; it's on my bug list and will be fixed in Version 1.2.

If your data has two objects with the same @id, their properties and their values are combined into a single object. That could cause properties to look like they have more values than you expect.
