         Principles for X3T5 Experimental File Storage at NIST

			    C. Michael Chernick
				   NIST  


The NIST has agreed to maintain an experimental file storage for X3T5
documents in order to expedite its work.  The following principles shall 
be used to maintain this file store:

1.  Files may be retrieved by anonymous FTP from OSI.NCSL.NIST.GOV
    Once logged in, enter the following:
             cd pub/x3t5 

2.  Retrieve the file "filelog.txt" to determine status of files in the X3T5 
    file store.
    Or enter the "ls" command for a list of files.

3.  File format is indicated by file name extension, e.g., 
	*.txt for plain ASCII Text files
	*.ps for PostScript files
	*.rtf for Rich Text Formatted files
	*.w51 for WordPerfect 5.1 (for DOS)
    	*.zip for PKZIP archived files (for DOS)

4.  Initially all files will be placed into a single directory.  If this
    proves to grow too large, subdirectories will be created as needed.  If
    so, E-mail will be sent to the X3T5 E-mail exploders to alert the 
    membership.

5.  If the file store grows too large, the NIST may delete older files.  
    Initially 40 megabytes will be allocated to this project.

  Placing files into the File Store

NOTE:  NO COPYRIGHTED MATERIAL SHOULD BE PLACED INTO THE FILE STORE!

1. To place files into file store, send a message to 
	x3t5-fs@osi.ncsl.nist.gov
    In the message indicate the author of the document to be placed into
    the file store, the format of the document, and the expiration date
    (if known) so that the file can be deleted when necessary.  If the document
    is to replace another file (e.g., this is a newer version), the file
    to be deleted should be indicated in the message.

2.  Binary files can be sent in E-mail messages by using the UUENCODE utility.

3.  Alternatively, for large files, it is possible to ftp into the directory 
    pub/incomming using anonymous FTP.  If this method is used, send the 
    appropriate message to x3t5-fs@osi.ncsl.nist.gov, as in instruction 1,
    and also indicate the name of the file in pub/incomming.  Files placed
    into pub/incomming will be moved by NIST staff into the pub/x3t5 directory
    and removed from the pub/incomming directory.  Any files placed into
    the pub/incomming directory without an accompanying E-mail message as in
    instruction 1, will be subject to immediate deletion.
