Project Description

Objective	Approach and Plan	Progress and Next Steps
Evaluate IPFS / NoSQL combination for MIC databases	Evaluate IPFS' PSK feature for "private clouds" Build prototype for scanning images put images / files into IPFS put metadata into NoSQL database (ElasticSearch is what we used at FME, CouchDB is what Steve used in Chronicle) Build prototype for browsing / showing images should update live when images appear in the DB should fetch image data from IPFS	IPFS stability and status 0.4.4 provided as binaries (recommended installation, very simple) 0.4.4 does not play well with up-to-date FUSE for macOS yet performance when listing directories not available on current machine is not good (several seconds delay) Performed several experiments that showed disappointing performance (maybe MIT wifi related?), but eventually successful transfers Data could be pulled from an internal network (without direct VPN connection) QmPyXW927iBPHVk3hfyzXAPGDpup26WGEh4LYK6da2xMhA is a TCGA subdirectory transferred to several project week participants' computers
