Thanks for this suggestion. I'd be interested in hearing feedback from people from the CHAS community who have used the system before deciding whether this is appropriate. I have two specific concerns at this point:

- Article tone: Any article that "guarantees" safety in its title (ChemStor: Using Formal Methods To Guarantee Safe Storage and Disposal of Chemicals) seems likely to be using the word in a way that is not well understood outside the author's intent. It appears that the logic the model uses is based on the CAMEO model and doesn't include issues like chemical concentrations and quantities to identify potential hazards. I am also concerned that the model uses technical computer language (e.g. "legal") in a way that could easily be mis-construed in other, more physical contexts.

- Use case definition: While there are interesting ways that this project could inform further collaboration between the chemical safety and chemical information communities, I don't know if the audience for this tool is well-defined yet. This is particularly true as the use scenarios described in the article occur in both Electronic Lab Notebook and home settings. The supplemental information for the article notes that "This code is for research purposes and is provided ??as is.?? Use at your own risk."

I do think that it is valuable for CHAS members to be aware of the tool's existence, both to consider its potential uses and also because some of the people we work with might use it without considering its limitations.
