Toxml

ToxML is a markup language initiated by Leadscope to promote adoption and use of controlled vocabularies and XML schema for storing chemical toxicity data.

ToxML has the two-fold objective of: a) supporting broadly encompassing and meaningful representations of toxicology experiments, with hierarchical schemes including various levels of complexity; and b) indexing the data with the chemical structures so as to permit the widest range of chemical biological interrogations of the database.
