MetPetDB is designed and built by a global community of metamorphic petrologists in collaboration with computer scientists at Rensselaer Polytechnic Institute as part of the National Cyberinfrastructure Initiative and supported by the National Science Foundation. MetPetDB is unique in that it incorporates image data collected by a variety of techniques, e.g. photomicrographs, backscattered electron images (SEM), and X-ray maps collected by wavelength dispersive spectroscopy or energy dispersive spectroscopy.
Purpose
[https://web.archive.org/web/20110720035915/http://metpetdb.rpi.edu/ MetPetDB] was built for the purpose of archiving published data and for storing new data for ready access to researchers and students in the petrologic community. This database facilitates the gathering of information for researchers beginning new projects and permits browsing and searching for data relating to anywhere on the globe. [https://web.archive.org/web/20110720035915/http://metpetdb.rpi.edu/ MetPetDB] provides a platform for collaborative studies among researchers anywhere on the planet, serves as a portal for students beginning their studies of metamorphic geology, and acts as a repository of vast quantities of data being collected by researchers globally.{{cite journal|doi=10.1029/2009GC002766|title=IMetPetDB: A database for metamorphic geochemistry|journal=Geochemistry, Geophysics, Geosystems|volume=10|issue=12|year=2009|url=http://europa.agu.org/?view=article&uri=/journals/gc/gc0912/2009GC002766/2009GC002766.xml&t=spear|author=Spear, F S|pages=n/a|bibcode = 2009GGG....1012005S |s2cid=129622082 |display-authors=etal|doi-access=free}}
Design
The basic structure of [https://web.archive.org/web/20110720035915/http://metpetdb.rpi.edu/ MetPetDB] is based on a geologic sample and derivative subsamples. Geochemical data are linked to subsamples and the minerals within them, while image data can relate to samples or subsamples. MetPetDB is designed to store the distinct spatial/textural context of mineral analysis that is a crucial to petrologic interpretation.{{cite journal|title=IMetPetDB; the unique aspects of metamorphic geochemical data and their influence on data model, user interface and collaborations|journal=Abstracts with Programs - Geological Society of America|volume=39|issue=6|pages=210ā211|year=2007|url=http://gsa.confex.com/gsa/2007AM/finalprogram/abstract_129415.htm|author=Pyle, J M|display-authors=etal}} A web-based user interface allows a user to become members and download their search results. Approved members may become contributors and upload data to catalogue and share with the public.

Contents
The database houses a wide range of information available for samples from all over the globe to be grouped into two categories: (a) observations and measurements (e.g. mineral data, images, chemical analyses), for which robust data models already exist, and (b) interpretative results (e.g. P-T conditions, crystallization ages, cooling rates, etc.), which are conclusions based on the observational data. Development of a robust data model for interpretative data is currently underway as of December 2010. The database system is beginning to incorporate a number of tools for data analysis and calculation that adds considerable power to the researcher.
MetPetDB differs from other Geochemistry relational databases (e.g. [https://web.archive.org/web/20070610152747/http://georoc.mpch-mainz.gwdg.de/georoc/ GEOROC], [http://www.navdat.org NAVDAT], PetDB) in that it incorporates unpublished data in addition to data published in peer-reviewed journals. The vast majority of data collected by metamorphic geologists is not presented in publication, and therefore a forum for sharing this data with the public is an objective of MetPetDB.{{cite journal|title=MetPetDB: New Directions for Metamorphic Studies|journal=American Geophysical Union, Fall Meeting 2008, Abstract #V13E-2155|year=2008|bibcode=2008AGUFM.V13E2155S|author=Spear, F S|volume=2008|pages=V13Eā2155|display-authors=etal}} Contributors to MetPetDB also have the ability to store private data and create projects, or collections of private, public, and published data for sharing and organization.
