Ecological Metadata Language
Encyclopedia
Ecological Metadata Language (EML) is a metadata
standard developed by and for the ecology
discipline. It is based on prior work done by the Ecological Society of America
and others, including the Knowledge Network for Biocomplexity. EML is a set of XML schema
documents that allow for the structural expression of metadata
. It was developed specifically to allow researchers to document a typical data set in the ecological sciences.
EML is largely designed to describe digital resources, however, it may also be used to describe non-digital resources such as paper maps and other non-digital media.
The Knowledge Network for Biocomplexity project has developed a software client specifically to address this need. Morpho is data management software intended for generating metadata in EML format. Morpho is part of the DataONE
Investigator Toolkit, and therefore intended to facilitate data sharing and reuse among ecologists and environmental scientists.
Metadata
The term metadata is an ambiguous term which is used for two fundamentally different concepts . Although the expression "data about data" is often used, it does not apply to both in the same way. Structural metadata, the design and specification of data structures, cannot be about data, because at...

Ecology
Ecology is the scientific study of the relations that living organisms have with respect to each other and their natural environment. Variables of interest to ecologists include the composition, distribution, amount , number, and changing states of organisms within and among ecosystems...

XML schema
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself...
