 I added this diagram to try to understand these pieces better.
-*RSP is missing from my picture
+*RDP is missing from my picture
-Thinking about exnodes and erasure codings.
-*L-Store writes extra erasure allocations.
-*L-Store can write a LoRS compatible exnode file that excludes the erasure allocations.
-**LoRS compatibility
-**LoRS does not have access to L-Store's capability to regain a file.
-Is this OK?
-*The data user does not need (and probably should not be bothered with) to handle error recovery.
-*data recovery, data warming, etc all are done by services/agents apart from the data consumer.
-*So what user interface and development API are needed by the data users?
-*command line tools
-**file movement
-**file system (some use the term namespace management) tools
-***list files, create directories, etc
-*C/C++ API
-**just need my simple offsets and lengths
-**would like to read a vector of data blocks (non-blocked reads)
-**don't want to deal with erasure stuff at this point.
-***is there a nice way to recover from errors?
