11 | | ChemoTyper includes ToxPrint. ToxPrint is a public set of chemotypes developed by Altamira LLC for FDA CFSAN’s CERES project. The ToxPrint contains three basic subsets: generic structural fragments, Ashby-Tennant genotoxic carcinogen rules (1989), cancer TTC categories (Kroes et. al. 2004). |

17 | 16 | == CSRML Reference Library Implementation == |
| 17 | The Chemical Subgraphs & Reactions Mark-up Language – CSRML – is a chemical XML language seen as a universal media describing the chemical (sub)structures and its query attributes, as well as the reactions and the transformations' rules. CSRML provides an open-source LGPL-licensed reference library that provides the generic I/O functionality for the CSRML documents. The reference library implementation includes modules |

23 | | * to validate CSRML content at the basic level, e.g., for checking syntax and semantic features against the language definition expressed by an XML Schema document. |

27 | | * to aid the developers to create GUI-based editors to input substructure queries in CSRML format, |
28 | | * to support the community and allow the easy exchangeability of the substructure queries between different programs and databases, and |
29 | | * to encourage the developers to create and distribute the CSRML extensions and software. |
