ro-crate in parquet files

[JervenBolleman]

Hi All,

Has anyone thought about embedding ro-crates inside parquet meta data for single parquet file objects?

Code to add custom metadata to a parquet file in python show here. Where the meta-data field name should probably be named 'ro-crate'.

Does this make sense? or would that go counter to the spirit of ro-crate?

Regards.

Your proposal has remembered me that RDF contents have been embedded in metadata fields of binary media and archive files in the past (see https://www.w3.org/2001/sw/BestPractices/MM/interop.html and https://en.wikipedia.org/wiki/Extensible_Metadata_Platform).

Maybe next RO-Crate specification releases can have some hints and conventions about embedding RO-Crate metadata in binary bundles, like Parquet, Jupyter Notebooks (see https://nbformat.readthedocs.io/en/latest/format_description.html#top-level-structure) or other scientifically popular bundle formats.
