The third example metadata standard, in JSON-LD format, is not about an analytical method at all.  Standard reference materials are vital resources in chemical analysis to show accuracy of new and revised analytical methods and verify the accuracy of chemical analysis over time.  Agencies that produce standard methods perform rigorous chemical analysis (using two or more analytical techniques) to report certified values for analytes.  Thus, ChAMP can be used to capture metadata about the material itself and also the methods of analysis used to determine analytes in the material.

For a second example of the use of ChAMP in creation of a standard (in JSON-LD format), we chose standard methods for obvious reasons. Standard methods of chemical analysis are published by many entities and for many application areas and while you can find many of these methods on the Internet searching for the most sensitive, or the one that best fits your application need is not always easy.  Extraction and annotation of metadata using ChAMP, as outlined below, is a great way to allow scientists to find what they need fast.
