IceCube是一个立方千米的中微子探测器，位于
南极。 IceCube 中文件的元数据传统上是经过处理的
基于应用程序，没有面向用户的访问权限。那里
数据文件一直没有统一的视图，用户经常查询文件系统
来定位文件。最近，我们致力于在一个统一的视图中创建一个统一的视图。
中央元数据目录。为了寻找一个简单的解决方案，我们创建了一个面向用户的
由 NoSQL 数据库支持的 REST API。所有主要数据生产者
将他们的元数据添加到这个中央目录中。模式生成已识别
作为多应用元数据服务的一个重要方面。
IceCube is a cubic kilometer neutrino detector located at the
south pole. Metadata for files in IceCube have traditionally been handled
on an application by application basis, with no user-facing access. There
has been no unified view of data files, and users often query the filesystem
to locate files. Recently effort has been put into creating a unified view in a
central metadata catalog. Going for a simple solution, we created a userfacing
REST API backed by a NoSQL database. All major data producers
add their metadata to this central catalog. Schema generation is identified
as an important aspect of multi-application metadata services.
