VFILM: A Value Function Driven Approach to Information Lifecycle Management Apr 2011 14 pages
Authors:  Jeffrey Cleveland; Joseph P Loyall; Jonathan Webb; James Hanna; Shane Clark; RAYTHEON BBN TECHNOLOGIES CAMBRIDGE MA
The full text of this report is available for sale.Information Management (IM) services need lifecycle management, i.e., determining how long persistent information is retained locally and when it is moved to accommodate new information. This is important when bridging IM services from enterprise to tactical environments, which can have limited onboard storage and be in highly dynamic situations with varying information needs. In this paper, we describe an approach to Value Function based Information Lifecycle Management (VFILM) that balances ...
