Latest production release. XDI-Validator is a standalone JSON Schema based validator for XDI files. XDI (*.xdi) is a format used to save XAS data. This validator aiming to be fully compliant with the XDI/1.0 specification, as detailed in XAS Data Interchange Format Draft Specification, version 1.0 and Dictionary of XAS Data Interchange Metadata. Changelog highlights: Make Mono.d_spacing conditionally required per XDI/1.0 spec by @smrgeoinfo. From @smrgeoinfo 's PR #6 : The XDI/1.0 specification requires Mono.d_spacing only when the abscissa (Column.1) is monochromator angle or encoder step count — the mono d-spacing is needed only to convert those units into energy: The Mono.d_spacing header field must be specified if the abscissa is conveyed as monochromator angle. The current schema requires Mono.d_spacing unconditionally, which produces spurious errors on the many XDI files whose abscissa is energy or wavelength (where d_spacing is optional).
