The Pistoia Alliance UDM project team - including members from BIOVIA, GSK, Novartis, and Roche - has announced the first release of the now-open Unified Data Model (UDM) file format specification which will facilitate the exchange of information about chemical reactions. The new update consists of a definition of the UDM file format (as an XML schema document), several sample datasets, and sample source code (in Python and Java) that demonstrate the conversion to the UDM file format and validation of UDM files.
The original unified representation of chemical reactions was co-developed by Elsevier and Roche with contributions from other pharmaceutical companies. It was donated to The Pistoia Alliance in 2017 with the aim of extending the model to support additional requirements, and to increase its adoption as a vendor-agnostic experimental reaction/data format standard.
The current release is compatible with the original version created by Elsevier; it will remove the previous uncertainty around the units of measurement used for individual numerical values and documents fundamental entities. It is expected that the update will facilitate the exchange of information about chemical reactions, and show the industry how it can work with UDM files. Going forward, the team is looking to introduce several enhancements which will increase representation of experiments captured in electronic laboratory notebooks (ELNs).
