Hi Teemu Daniel,

Those packages were developed before ExperimentHub.

Please follow the current standard for experiment data packages at


You may want to take a look at curatedTCGAData as an example 
(disclaimer: I developed the package).
It is advisable to split the resources into more modular components, 
e.g., colData, sampleMap, data assays
rather than distribute serialized MultiAssayExperiment objects.

IMO, there should be no compatibility issues as the changes would only 
affect the underlying code and
not the user interface.

Best regards,
