CML (.cml) is an open XML standard for representing chemical data and metadata. It is a standardized, platform-independent format used to store data like chemical structures, properties, and so on. This file extension is supported by the Chemical Markup Language consortium who further actively develops this format to make it wider adopted. The CML markup language follows the W3C XML standard and uses XML-based technologies to define the layout of the language.
Features of CML File Type
The main purpose of CML is to help with data exchange, integration, storage, and annotation in a machine-readable format. It provides a wide range of features including support of the IUPAC International Chemical Identifier (InChI), graphic representation from XYZ coordinates, schema checking and validation, support for multiple document pages within one CML file, full support of MOLFormula and MOLWeight, as well as databases representation. CML also benefits from an active community open-source development effort and widespread adoption of XML technologies in chemistry.
Similar File Extensions
Similar formats include (.cif), (.cdx), (.rxn), (.smi), (.mol2), and (.sdf). These file extensions can be opened with any chemical drawing software such as ChemDraw or Marvin JS. The main advantage of CML over these is its human-readable markup format which makes it easier to search data in different application domains.
Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CML) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CML extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CML file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CML extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CML extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CML file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CML file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CML file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CML file) will be extended to the maximum.
It is also good to check
- if the .CML file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
