What are the various data object interfaces supported by SRB?
The SRB supports four types of interfaces. The first type is a stream interface. It allows Unix file operations such as open, close, read, write and seek on SRB data objects. The second is an object-level interface. It provides means to create, modify and destroy collections of objects, move, copy and replicate objects, and apply user-defined proxy operations on objectsto obtain a new type of the object. The third type is a discovery-level interface for obtaining meta data information about data objects (eg., replication information, ownership, access, location, type information, etc), resources and users. These operations accessthe information located in MCAT catalog. Finally, SRB provides an interface for modifying the data about data objects in SRB, and for performing access control and auditing on various SRB objects.
