A description of: The CAMASE Register of Agro-ecosystems Models  A registry of "relevant models used in Europe for research, education and application in: intensively and extensively produced agricultural crops, grasslands, forests, and their environments; cropping and farming systems, farm households, land use; shells for such models; tools for such models in DSS-applications (e.g. microclimate profiles for irrigation scheduling)."

one example of metadata for a geospatial data used by the EPA following the FGCD standards

http://www.epa.gov/ostwater/P-ROUTE/metadata.txt.html
metadata for P-Route, a model used by the EPA

another example of EPA metadata on another model

http://164.214.2.59/GandG/metadata/metadata.html
This site is the index page of metadata for a number of NIMA Geodesy and Geophysics models. They addapted the FGDC geospacial data standard to apply to models.  An interesting adaptation.

http://www.wcc.nrcs.usda.gov/water/factsheets/awm.html
An example of metadata out of the USDA, Natural Resources Conservation Service.

http://www.mesc.usgs.gov/metadata/salmod-metadata.html
An example of metadata documentation for a model from USGS.  Nice format simular to that of the FGDC geospatial standard.
