Box
· Box is an add-on framework for Java applications that performs asynchronous gathering of source data with subsequent processing or transformation of that data into output JSON documents and exposing those documents through a web API. Box excels at maintaining existing documents including keeping them up-to-date in real time and deleting them when required. Box supports aggregating data from multiple sources as well as splitting data into multiple documents. How documents are processed is left up to each application. The web api makes the documents available by ID or by harvesting all documents. Harvests can be filtered using facets and documents can be pared down by requesting only needed fields.
