CLAVAS:

-> conceptscheme , conceptscheme/{id}[.html]

-> find-concepts

Check:

1. conceptScheme parameter in the list of parameters is obsolete. I have made it "scheme" so it is the same as in picturae code (used by Beeld en Geluid)
2. According to run these examples, it should work for parameters you need, after correcting conceptScheme to scheme.

1. Examples similar to examples above, like

Need to know exact query parameters you use for CCR, for more thorough check.
