EML is a metadata specification developed by and for the ecology discipline. It is a set of XML* schema document types that can be used in a modular and extensible manner to document ecological data.


EML is based on prior work done by the Ecological Society of America and associated efforts (Michener et al., 1997, Ecological Applications).


Developed specifically to allow researchers to document a typical data set in the ecological sciences.


Long term Ecological Research Network (LTER) was founded by the National Science Foundation (NSF) to conduct research on ecological issues that can last decades and span huge geographical areas. For over 30 years, the Network has generated thorough site-based scientific research that has led to valuable findings on regional and continental scales.

*XML (Extensible Markup Language) defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. Although the design of XML focuses on documents, it is widely used for representation of arbitrary data structures - such as those used in web services.
