ONS Solubility Web Query
Rajarshi Guha created a web interface for the solubility data that we've been collecting in a GoogleDoc spreadsheet as part of the Open Notebook Science Challenge. There are convenient drop-down menus for solvents, solutes and you can even put in a range of solubilities. Duplicate runs should show up nicely for comparison. The solute molecules are also rendered as images.
In this example, Rajarshi is using an SQL database but it would be convenient to query the RDF data directly using similar types of interfaces.
And no matter how many ways we shuffle or reformat data there will always be a link to the original lab notebook page that generated each measurement. There isn't any reason to break the chain of provenance all the way to the peer-reviewed article when it is time.
