The OSCARS CDIF-4-XAS project is pleased to announce the publication of an extra deliverable (D3) the CDIF-4-XAS Implementation Plan.
CDIF-4-XAS Implementation Plan https://doi.org/10.5281/
This document describes the first proposal to integrate the IXAS — and IUCr — recommended formats for X-Ray Absorption Spectroscopy (XAS) data into workflows in the data processing and analysis platform Galaxy using the CDIF-4-XAS profile.
The OSCARS project CDIF-4-XAS aims to advance cross-domain interoperability of XAS data by implementing the Cross-Domain Interoperability Framework (CDIF) using the Data Description Initiative’s Cross-Domain Integration (DDI-CDI) model.
The project has concluded the two first steps of its roadmap. Firstly, the domain familiarisation step helped to identify two major standards within the XAS community: NeXus XAS (NXxas) and the XAS Data Interchange format (XDI). The NXxas and XDI standards are the focus for harmonization of data description and formatting recommended by the International X-ray Absorption Society (IXAS) and the International Union of Crystallography (IUCr). Secondly, in the metadata modelling step, both NXxas and XDI were mapped to CDIF following the DDI-CDI recommendation where the main output was the definition of a variable cascade, that describes and harmonises both standards from the level of concepts and representation down to the level of instances.
This document focuses on the third phase of the roadmap: the development of implementation guidelines supported by working examples. We now turn to practical guidance for building interoperable, domain-agnostic solutions that enable FAIR data exchange.
