Make quality reports available on disk

[gothub]

It was mentioned at the weekly development meeting that the quality reports that the metadig engine creates should be made available on disk, in a manner similar to how metacat stores files on disk. Other services can then have bulk access to these reports for further processing, aggregation and any other kind of analysis.

If the reports are made available in this manner, would it be necessary to include metadata in the file and directory names to assist in locating the desired file? For example, we might have

/mnt/glusterfs/metadig-engine/reports/knb.suite.1/doi:10.6085_AA_CMRX00_XXXITBDXLSR01_20030717.50.5.json

In his case, the pid would have to be changed so that the filename is legal (on Ubuntu).

Would any other info need to be stored in the directory or filename, or would they all be stored in a single directory and any metadata would be made available via a database or some other mechanism?

What format types would have to be generated and stored as well, i.e. (XML)?

Would this disk store be made available via nfs? As these would be stored via glusterfs on the k8s
cluster, they could also be made available via gluster over a network connection.

Thoughts @mbjones @csjx ?
