Welcome to dcmp.dev. This site is primarily a distribution point for the DCMP Editor, which you can download here. To find out more about the Digital Construction Material Passport (DCMP), please visit materialpass.org.
The DCMP XSD can be downloaded here.
There is also an interactive documentation of the XSD available.
Even though a DCMP file really consists of XML, it should always use the file extension ".dcmp".
The correct Media Type to use with a DCMP file is "application/vnd.dcmp+xml". For details, see the official IANA registration.
