Libgta implements the Generic Tagged Arrays (GTA) file format. GTAs can store any kind of data in multidimensional arrays, optionally with simple tags to store rich metadata. GTAs are streamable and support mupltiple compression methods. Uncompressed GTAs allow easy out-of-core data access for very large arrays.
The eXtensible Binary Universal Protocol (XBUP) project is an attempt to design a general binary communication protocol and file format. It is based on the unlimited unary-binary encoding and strongly typed block tree structure. It will provide a catalog service and processing infrastructure.
