"On chemical structures, substances, nanomaterials and measurements" Nina Jeliazkova, Ideaconsult This talk attempts to highlight how I came to recognize the fundamental role of measurements, coming from the realm of data modelling and data analysis. Besides retaining the data provenance it provides insights how do we go beyond chemical structures and address the challenges of representing the identity of chemical substances and nanomaterials (with examples from the latest developments of AMBIT web services and OpenTox API). Finally, supporting the vision of distributed, open, web-like approach towards recording subtle experimental details is essential, not only for the chemists and biologists in the labs, but for all of us using, modelling, storing and querying the data.
