CHML stands for "Chemical Markup Language," which is an XML-based format used to represent chemical information. It allows for the structured storage and sharing of data related to chemical compounds, reactions, and properties, making it easier for researchers and scientists to exchange information. This markup language is particularly useful in fields like computational chemistry and bioinformatics, where accurate representation of chemical structures is essential. By using CHML, researchers can create standardized documents that facilitate collaboration and data analysis across various platforms and software applications.
