MetPetDB: A Database for Metamorphic Geochemistry

MetPetDB（变质岩石学数据库）是伦斯勒理工学院通过以前的地理信息学资助开发的数据库和协作套件。MetPetDB是为已发布数据的存档而设计的，是研究人员和学生访问大量可用信息的接入点，是不同机构研究人员之间的协作工具，也是研究人员之间数据分析和网络互动的来源，最终目标是培育新的和创新的科学。它为地球科学领域强大的网络基础设施迈出了第一步，在这个基础设施中，已发表和未发表的数据可以与社区共享，共同用于研究，并通过选择、评论和参考进行管理。在这个项目中，pi将开发一些新的和创新的功能，以增强当前的系统，并继续向其填充数据，通过使用网络基础设施进一步改善这一全新科学的愿景。MetPetDB系统的数据模型基于变质样品和子样品，并将样品特征，图像和化学分析之间的无缝集成作为基本设计元素。MetPetDB的这一方面在地球科学中是独一无二的，其结果在其他图像密集型学科中也有应用。数百份样本和数千份化学分析已经上传到系统中。

MetPetDB (Metamorphic Petrology Database) is a database and collaboration suitedeveloped at Rensselaer Polytechnic Institute through a previous Geoinformatics grant. MetPetDB is designed for archival of published data for ready access, an access point for researchers and students to the enormous volume of available information, a collaboration tool among researchers working in different institutions, and a source for data analysis and networking interactions among researchers with the ultimate goal of fostering new and innovative science. It provides a first step for a robust cyberinfrastructure in the geosciences where published and unpublished data can be shared with the community, used in research collectively, and curated by its use through selections, comments and references. In this project, the PIs will develop a number of new and innovativefunctionalities to enhance the current system and continue populating it with data to further improve on this vision of a completely new science through the use of cyberinfrastructure. The data model of the MetPetDB system is based on metamorphic samples and subsamples and incorporates seamless integration between sample characteristics, images and chemical analyses as a fundamental design element. This aspect of MetPetDB is unique in the geosciences, and their results have application in other, image intensive, disciplines. Severalhundreds of samples and thousands of chemical analyses are already uploaded to the system.
