MARS - A Message Archiving & Retrieval Service

I. Introduction


This document describes a Message Archiving and Retrieval Service

(MARS) which has been developed at Computer Corporation of America; it

utilizes the Datacomputer, a network database utility developed by CCA

for ARPA. [Research and development of a prototype MARS system was

supported by the Defense Advanced Research Projects Agency of the

Department of Defense, under the ARPA Very Large Databases program,

and was monitored by the Office of Naval Research under Contract No.


The Service is available, primarily, to groups for storage of

teleconferencing transcripts. Is is also available, upon request, to

individual ARPANET correspondents.

There are both 'public' and 'private' messages in the database.

Public messages may be retrieved by anyone. The public collection

includes the messages of the Header-People [@ MIT-MC] group, and the

MsgGroup [@ USC-ISI] proceedings.

Private messages may be retrieved only by the users who have archived

them, or anyone whose name appears on the list of message recipients.

Messages archived using MARS are heavily indexed and can be retrieved

in a variety of ways, including Boolean combinations of message

recipients, message composition date, any text words in the message

subject, and text words in the message body. The MARS facilities are

integrated very naturally into the existing collection of

message-handling tools:

. A message is designated for archiving by sending it to

MARS-Filer @ CCA using one of the usual message-mailing tools such


. A message is designated for retrieval by sending a request as

ordinary mail to MARS-Retriever @ CCA.

The Filer program checks for mail every hour; the Retriever program

checks every quarter-hour. The periodicity can be altered to meet

demand but the intent is for MARS to operate as a background job and

only during extremely low-activity periods.

The next section (II) describes the indexing operation in greater

detail, and how to archive and retrieve messages. The last section

(III) is an extractable user card.
