1.    IDENTIFICATION OF PROPOSED PROJECT
1.1   TITLE:  SCSI-3 Trash Commands (STC)
1.2   PROPOSER:  The other guy...
1.3   DATE SUBMITTED:  April 1, 1995
1.4   PROJECT TYPE:  D - Development of standards within an X3 TC 
      (more or less).


2.    JUSTIFICATION OF PROPOSED STANDARD
2.1   NEEDS:

Recently, the United States Senate announced the creation of the first
electronic communications technology developed solely by a committee of
non-experts.  The technology is called, Talk Till You Drop (TTYD).  A key
component of the TTYD technology is the Write Once Read Never Gigantic
device (WORNG, pronounced wrong).  [Fortunately, WORNG devices are not
constrained by the typical byte-ordering rules.] 

The unique work of the U.S. Senate obligates the X3T10 committee to propose
project to add a SCSI-3 standards definition for the WORNG device.  The
proposed document for addition of the WORNG device to SCSI-3 is the SCSI-3
Trash Commands (a.k.a. the SCSI-3 Trash Can, or STC).


2.2   RECOMMENDED SCOPE OF STANDARD:

The proposed STC standard will be a fully compliant (if somewhat maggot
infested) command set component of the SCSI-3 family of standards.  How-
ever, some have called the STC "the dregs of SCSI" and requested that it
appear outside the box on the SCSI Roadmap. 

The STC standard aims are:

   a) provide a housekeeping service of other members of the SCSI-3
      standards family.
   b) define, once and for all, the bit-bucket.
   c) act as a repository for ideas that lack consensus support (e.g.,
      reserved field checking, using Morse Code as a SCSI transport, and
      the L-cable).
   d) compost germane issues until they are ripe for reintegration in other
      SCSI activities.

Consideration also may be given to incorporating compaction technology in
the STC.  If this is done, appropriate experts (such as Kitchen Aid and
Kenmore) will be consulted.

The STC will NOT support bit recycling.  Once an idea hits the STC, it's a
goner!


2.3   EXISTING PRACTICE IN AREA OF PROPOSED STANDARD:

Trash handling and issues composting have long be key activities of large
committees, such as X3T10 (objections to this scuzzy interpretation not
withstanding).  Extensive research has been conducted in areas of concern
to the STC for many years (e.g., "The Preparation of Pure Crap", M. Kaye,
"The Journal of Irreproducible Results", Vol 17, No 1, August 1968, pgs.
9-11).

The WORNG device has yet to be standardized.  However, the committee will
have vast resources to draw upon, in addition to its own innate skills.


2.4   EXPECTED STABILITY OF PROPOSED STANDARD WITH RESPECT TO CURRENT AND
      POTENTIAL TECHNOLOGICAL ADVANCE:

Trash technology almost predates civilization.  In any case, the trash can
has been around for many decades.  The WORN (write-once read-never) device
has been described since the dawn of electronic computing.  The WORNG
device is a more recent creation, made possible by the general increase
in the capacities of storage technology devices.

Certainly, there is every reason to believe that trashy technology will
remain every bit as stable as SCSI technology, maybe more so.  Should this
drivel change, well, there is always STC-2.


3. DESCRIPTION OF PROPOSED PROJECT:
3.1   TYPE OF DOCUMENT:  Standard.

3.2   DEFINITION OF CONCEPTS AND SPECIAL TERMS:  None.

3.3   EXPECTED RELATIONSHIP WITH APPROVED X3 REFERENCE MODELS:

The STC will fully conform to the SCSI-3 Architecture Model (SAM), provid-
ing a new device model (sic) and command set (ha) within that context. 
Every effort will be made to prevent seepage of STC concepts to the SAM.

WORNG devices may be incorporated in RAID configurations, thus relating the
STC to the SCSI-3 Controller Commands (SCC).  The industry acronym for this
concept is WRIGHT (WORNG RAIDs In Garbage-bags Held with Tie-wraps).  As
Prof. Lawrence L. Litter observed, this finally establishes the principle
that two WORNGs do make a WRIGHT.


3.4   RECOMMENDED PROGRAM OF WORK:

The following program of work is planned for the STC standard:
   1) Trashing the neighbors.
   2) Soliciting refuse from all the usual suspects.
   3) Establishing refusal procedures for the refuse received above.
   4) Thrashing out an odoriferous standard based on the remaining refuse
      and littering same with recondite references to otreh sandtards.
   5) Canning it.
   6) Tossing the draft proposed standard in the X3.BIN for further
      trashing.


3.5   RESOURCES - INDIVIDUALS AND ORGANIZATIONS COMPETENT IN SUBJECT
      MATTER:

The current membership of X3T10 includes hog farmers, hod carriers and
representatives from all parts of the computer industry from semiconductor
chip manufacturers to large mainframe system manufacturers as well as
Government agencies, middle-management and street sweepers.  No self-
respecting member of X3T10 wants to touch the STC.  However, all have
recognized that this manure must be shoveled and have consented to don
their hip-waders and write this standard.

There are sufficient resources to complete the development of this standard
without delaying work on other standards.  As noted above, the STC could be
considered to be a normal by product of committee work.


3.6   RECOMMENDED X3 DEVELOPMENT TECHNICAL COMMITTEE:

The X3T11 TC has recommended that the development work be done in Technical
Committee X3T10.  X3T10 would like to find another committee to recommend. 
But, as the nominal owner of all things SCSI, things look ominous for
X3T10.


3.7   ANTICIPATED FREQUENCY AND DURATION OF MEETINGS:

Technical Committee X3T10 meets bi-monthly.  The STC meetings will be too
frequent and too long.  Otherwise, the STC will not contain everything that
it should.


3.8   TARGET DATE FOR dpANS TO X3:  April 1, 1997

3.9   ESTIMATED USEFUL LIFE OF STANDARD:

Depending on the respondent, the STC useful life may be anything from
dead on arrival to the keystone of modern civilization.  [Admittedly,
one respondent was a little biased.]


4. IMPLEMENTATION IMPACTS
4.1   IMPACT ON EXISTING USER PRACTICES AND INVESTMENTS:

Given the ubiquitous and yet elastic nature of WORN technology, the growth
path for WORNG technology and the STC should be no more painful than a
killer-bee sting.  However, the negatives should impact the positives in
manner resembling a wisdom-tooth.


4.2   IMPACT ON SUPPLIER PRODUCTS AND SUPPORT:

Product suppliers are more than mildly leery of the STC.  Given the trash
that they are working with now, however, the STC project is their great
white hope (well, dingy grey) (would you believe Darth Vader Black).


4.3   TECHNIQUES AND COSTS FOR COMPLIANCE VERIFICATION:

The compliance verification method applied to the STC will be based on
the concepts first characterized in the classic tale, "The Emperor's New
Clothes."  In this way, compliance can be verified without consuming any
resources of any kind.  Compliance verification costs will be correlated
to the services performed and will be the responsibility of anyone
imprudent enough to pay them.


4.4   LEGAL CONSIDERATIONS:

All known legal considerations are so mired in muck as to be
inconsequential.  A Call for Patents will be made, but not heard.


5. CLOSELY RELATED STANDARDS ACTIVITIES
5.1   EXISTING STANDARDS:  Are you kidding?

5.2   X3 STANDARDS DEVELOPMENT PROJECTS:
      Several, but nobody wants to admit it

5.3   X3 STUDY GROUPS:  
      The Madonna Fan Club.

5.4   OTHER RELATED DOMESTIC STANDARDS EFFORTS:
      The Official Cow Chip Tossing Rules Committee.

5.5   ISO/IEC JTC 1 STANDARDS DEVELOPMENT PROJECTS:
      The STC will be considered for proposal to JTC1/SC25/WG4, 
      if they have the stomach for it.

5.6   OTHER RELATED INTERNATIONAL STANDARDS DEVELOPMENT PROJECTS:  
      Russian Environmental Protection Planning
      Antarctic Landfill Planning
      Save the Skeets Foundation

5.7   RECOMMENDATIONS FOR COORDINATING LIAISON:
      Lefty Longthrow (sanitation engineer).

5.8   RECOMMENDATIONS FOR CLOSE LIAISON:
      None.  Nobody wants to get close to this stuff.
