The Dataset Project provides tools for working with collections of JSON documents. It uses a simple key and object pair to organize JSON documents into a collection. It supports SQL querying of the objects stored in a collection.
It was designed for temporary storage of JSON objects in data processing pipelines. It can be used as persistent storage mechanism for collections of JSON objects you wish to distribute when used in conjuction with pairtree or SQLite3 storage.
The Dataset Project provides command line programs and a web service for working with JSON objects as a collection or individual objects. As such it is well suited for data science projects as well as building web applications that work with metadata.
