"This document illustrates an example showing how to go from a bids dataset to a JSON-LD BIDS dataset. More specifically, one wants to : \n",
"- add gently context into existing json files : T1w.json, taskxxx.json\n",
"- create an other JSON file with attached JSON-LD context to store metadata only present in the BIDS directory (bids_context.json findable at that location: https://github.com/incf-nidash/bids-ld/pull/1)"

"1st step : we review existing JSON files with the metadata types in BIDS and compare them to the NIDM-Experiment data. \n",
"--> we list the bids attributes, the path to bids terms, the nidm attributes and their links to nidm objects. \n",
"\n",
"2st step : we create a context file only for bids terms labelled 'bids_context.json'.\n",
"--> At this time there is still no URIs for BIDS, so one must create one with the following prefix: \n",
" \"bids\": \"https://bids.neuroimaging.io#\"\n",
" Then to describe bids attributes : \n",
" \"Name\" : \"https://bids.neuroimaging.io#Name\"\n",
" \n",
"3rd step : we add this gently context into existing json files. "
