I know IPFS is happy to help with implementation advice on discuss.ipfs.io or #ipfs on IRC, they did for me.
It does depend on the scale of your data and whether you want upload data in a streaming or discrete fashion. If by segmentize you mean to like chunk your data into smaller sections, then that is handled automatically by both DAT and IPFS.
Any recommendation on how to make time series data available via Dat or IPFS is highly appreciated.
There will be base data of different systems and experiment data from experiments running in those environments. So far I have no concrete idea on how to segmentize and make available the data in a sensible way.
