Design Decisions (6)
File names and URLs
- LFN – Logical File Name (unique to Grid)
- Can have path
- e.g. CERN-dataset-7/run17/part1/file-123
- SURL – Site File Name
- Not necessarily “physical” file name
- Site can map to one or more “physical” files
- Consistent with Fermilab’s SAM
- e.g. srm://sleepy.lbl.gov:4000/tmp/foo-3000
- TURL – Transfer file name (WP2 suggestion)
- SRM selects protocol and physical file
- e.g. gridftp://dm.lbl.gov:4000/home /level1/foo-3000
- StFN – Storage file name
- Advisory suggestion by client on “srmPut” and “srmCopy”
- e.g. sleepy.lbl.gov:4000/tmp/foo-3000
