MetPetDB: A Database for Metamorphic Geochemistry

变质岩石学数据库是伦斯勒理工学院通过之前的地理信息学拨款开发的一个数据库和协作套件。MetPetDB旨在对已发表的数据进行存档，以便随时访问，是研究人员和学生访问海量可用信息的访问点，是在不同机构工作的研究人员之间的合作工具，也是研究人员之间数据分析和网络互动的来源，最终目标是促进新的和创新的科学。它为地球科学中强大的网络基础设施迈出了第一步，在那里，已公布和未公布的数据可以与社区共享，共同用于研究，并通过选择、评论和参考资料进行管理。在这一项目中，绩效指标将开发一些新的和创新的系统功能，以加强当前的系统，并继续向其填充数据，以通过使用网络基础设施进一步改进这一全新科学的愿景。MetPetDB系统的数据模型以变质样品和亚样品为基础，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，他们的结果在其他图像密集型学科中也有应用。数百个样本和数千个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 It provides a first step for a robust cyberinfrastructure in the geosciences where published and unpublished data can be shared with the community, used in research collectively, and curated by its use through selections, comments and references.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.
