LoCI FAQ (Frequently Asked Questions)



Category: Main -> ExNode FAQ

Question
·  What is the exNode and exNode library?
·  What is the exNode logical length?
·  What is the format of the exNode?

Answer
·  What is the exNode and exNode library?

The exNode is a generic data structure used for the aggregation and serialization of metadata. LoRS uses the exNode to catalogue IBP capabilities as well as the associated metadata for end to end conditioning and file fragmentation. The exNode library has no data transfer routines. It is only a simple catalogue of metadata. All semantics and functionality are added by LoRS.

·  What is the exNode logical length?

The exNode logical length is set by the LoRS library. When the data is end to end conditioned some data may be added or diminished by compression. The "logical length" is the original length of the data, irrespective of the physical length.

·  What is the format of the exNode?

All exNodes use XML for serialization so that you can upload a file on one OS and send the exNode file to another user on a different OS.
