Advice for applying Bioschemas to BBMRI Directory

Dear Bioschemas Members,
I am Vittorio Meloni and I'm collaborating with BBMRI to add Bioschemas
into the Biobanks' Directory. In particular, I need to represent Biobanks
and Collections concepts, which are compliant with the MIABIS 2.0 model:
the Biobank is the organization that stores samples and data related to the
samples while a Collection is the set of samples. According to these
definitions, I mapped the Biobank to DataCatalog, using the "provider"
attribute to describe the organization and the "dataset" attribute for the
list of Collections, and the Collection to a Dataset. Do you think this
mapping would be correct?
Another issue I have is how to add additional properties to a Collection:
for example, how can I express that a Collection collects materials as DNA?
With the DataRecord I could use additionalProperty, but it is Deprecated
now. I've found the variableMeasured property but I'm not sure it fits
correctly. Do you think that's the right way to go?

Any suggestion or comment would be appreciated.
Thank you,
Vittorio
