141101 - Follow up ref SDS 64 0000, ref SDS 63 0000.
141102 -
141103 - Paul submits information on the Pointrel Data Repository System he has
141104 - developed over the past 20 years, implemented using Python, which is
141105 - the same system used for Zope which the DKR team plans to use for
141106 - improving email.  Possibly Pointrel can be configured to enhance Zope.
141107 - Paul does not say how Pointrel might solve issues he cited earlier on
141108 - 000405 about developing useful knowledge representation.  He provides
141109 - code and or information under a particular open source license, and
141110 - seems to expressly prohibit application for DKR project.

141502 - Pointrel Data Repository System Information Storage Architecture
141503 - License X11/MIT Open Source for Pointrel Data Repository
141504 -
141505 - Received ref DRT 1 0001 from Paul Fernhout submitting, primarily to
141506 - Eric Armstrong, possibly some specific code for accomplishing data or
141507 - knowledge representation to support Eric's specification on the
141508 - OHS/DKR editor, which was submitted on 000508, ref SDS 64 0782, and
141509 - reviewed in depth on 000505. ref SDS 63 0001
141510 -
141511 - Paul advises that this version of Pointrel Data Repository system is
141512 - made available under an X11/MIT "open source" type license.
141513 - ref DRT 1 1827  He further states...

141515 -        [On 000601 Paul Fernhout favorably impressed by SDS record
141516 -        analysing his letter today on Pointrel. ref SDS 67 0851
141517 -      ..
141518 -      He submits this letter to people as interested individuals,
141519 -      not in any way as an extended activity of the Engelbart
141520 -      Colloquium in which he has participated, and not as a
141521 -      contribution to any related code base for that colloquium.  This
141522 -      is for liability & other reasons, and hopefully someday soon such
141523 -      disclaimers will not be an issue when/if the Engelbart Colloquium
141524 -      "open source" vs. "permission to use" issues discussed in that
141525 -      colloquium are resolved. Note that the license does not prohibit
141526 -      use of the code by any organization, as long as they abide by the
141527 -      terms of the license including accepting the disclaimer of
141528 -      liability. ref DRT 1 2684

141531 - Background
141532 -
141533 - On 000405 Paul explained challenge of developing data structures for
141534 - knowledge representation. ref SDS 48 0005  He advised at that time
141535 - much of the research in knowledge representation is not useful,
141536 - ref SDS 48 4611, perhaps because it is difficult to program for
141537 - flexibility needed in knowledge representation. ref SDS 48 3600
141538 -
141539 -      Does Pointrel and Tridal Data Storage reflect a solution to
141540 -      difficulties Paul cited on 000405?
141541 -
141542 - On 000505 called on Paul and others to support Eric on developing
141543 - OHS/DKR program requirements. ref SDS 63 4864
141544 -
141545 - Today, Paul explains that Pointrel Data Repository System is a loosely
141546 - coupled set of concepts for data representation. It can be thought of
141547 - as an information storage architecture. ref DRT 1 2695
141548 - ..
141549 - The code referenced here implements the simplest concepts in
141550 - this system. William Kent's...

141556 - ....ROSE/STAR system described in his 1979 book "Data and Reality" is
141557 - similar to the Pointrel Data Repository System in intent in many ways.
141558 -
141559 - Future versions may include support for operating directly under
141560 - Squeak (in Smalltalk) and as a Server. ref DRT 1 1316
141561 -
141562 -
141563 -  ..
141564 - Triadal Data Storage Supports Arbitrary, Complex Networks
141565 - Records, Objects, Strings, Relationships
141566 -
141567 - Pointrel Data Repository System includes a triadal data storage
141568 - system. Using triads, one can build arbitrary complex networks of
141569 - relationships.
141570 - ..
141571 - These dynamic relationships can define the equivalent of records
141572 - or objects in a database. Triads are simply groups of three pointers
141573 - that can point to other triads. In addition, as a concession to
141574 - efficiency, each triad can be associated with a string. Rather than
141575 - focus on lists or objects, Pointrel focuses more on relations.
141576 - ref DRT 1 1920
141577 -
141578 -     This may help Eric with his question on 000227 about how to
141579 -     organize case study information, which he feels is useful but
141580 -     difficult to manage with technology. ref SDS 35 0001
141581 -
141582 -     Need example of application for tiradal data storage, what kind of
141583 -     data is stored, and how might it support knowledge management?
141584 -
141585 -     Paul says an example is in a follow up letter. ref DRT 1 1664

141592 - Elegant Design Needed to Solve Knowledge Management Dilemma
141593 - Flexibility, Speed, Simplicity Require Elegent Design
141594 -
141595 - Pointrel strives for an elegant compromise between flexibility, speed,
141596 - and simplicity in storing and retrieving information.  The Pointrel
141597 - system aims at having a small number of unifying concepts that can be
141598 - arranged in endless ways to build layers of complexity above them.
141599 - ref DRT 1 3564
141600 -
141601 -     How can Paul's Pointrel method contribute to SDS?
141602 -
141603 -     Paul's goal to balance speed, flexibility and simplicity may
141604 -     support the POIMS objective to solve the knowledge management
141605 -     dilemma of understanding complexity with summary for perspective,
141606 -     but without hiding critical details, ref OF 1 8774, as set out in
141607 -     the record on 950626, ref SDS 2 2882, again on 960322, ref SDS 3
141608 -     7749, and again on 970116, ref SDS 4 1732, which requires
141609 -     integreating different kinds of computer tasks, implemented by SDS
141610 -     at both the data management and the work process level.

170502 - Python Implemented by Pointrel Data Repository, 20 Year Effort
170503 - Zope May Work with Pointrel Based on Common Implementation of Python
170504 -
170505 - Paul advises that this initial distribution is one possible
170506 - implementation in Python of this "idea", which he has been developing
170507 - in various languages for about twenty years. ref DRT 1 2592
170508 -
170509 - This may provide development path with Zope which the DKR project
170510 - plans to use for improving collaboration using email, reported on
170511 - 000504. ref SDS 62 3944
170512 -
170513 -    On 000422 Paul cited Python as an example of an acceptable open
170514 -    source license, ref SDS 53 5900, evidently based on his experience
170515 -    developing Pointrel Data Repository system.
170516 -    ..
170517 -    On 000427 Python is cited by Jack Park in a presentation on
170518 -    system architecture using WBI and in connection with DOM technology
170519 -    being considered by the DKR project. ref SDS 56 1092

170521 -    On 000428 Eric Armstrong asks how good a language is PHP for DKR
170522 -    purposes, vs. Python? ref SDS 57 3430  Paul's submission today may
170523 -    address that issue.
