Clarification on the source vs raw language.

1.0.0

1.0.0-rc4

Replaced links to neurolex with explicit DICOM Tags.
Added sourcedata.
Added data dictionaries.
Be more explicit about contents of JSON files for structural (anatomical) scans.

1.0.0-rc3

Renamed PhaseEncodingDirection values from “x”, “y”, “z” to “i”, “j”, “k” to avoid confusion with FSL parameters
Renamed SliceEncodingDirection values from “x”, “y”, “z” to “i”, “j”, “k”

1.0.0-rc2

Removed the requirement that TSV files cannot include more than two consecutive spaces.
Refactor of the definitions sections (copied from the manuscript)
Make support for uncompressed .nii files more explicit.
Added BIDSVersion to dataset.json
Remove the statement that SliceEncodingDirection is necessary for slice time correction
Change dicom converter recommendation from dcmstack to dcm2nii and dicm2nii following interactions with the community (see moloney/dcmstack#39 and https://github.com/neurolabusc/dcm2niix/issues/4).
Added section on behavioral experiments with no accompanying MRI acquisition
Add _magnitude.nii[.gz] image for GE type fieldmaps.
Replaced EchoTimeDifference with EchoTime1 and EchoTime2 (SPM toolbox requires this input).
Added support for single band reference image for DWI.
Added DatasetDOI field in the dataset description.
Added description of more metadata fields relevant to DWI fieldmap correction.
PhaseEncodingDirection is now expressed in “x”, “y” etc. instead of “PA” “RL” for DWI scans (so it’s the same as BOLD scans)
Added rec-<label> flag to BOLD files to distinguish between different reconstruction algorithms (analogous to anatomical scans).
Added recommendation to use _physio suffix for continuous recordings of motion parameters obtained by the scanner side reconstruction algorithms.
