400810 - ..
400811 - Collaboration is a Basic Need
400813 - One of the most fundamental barriers to collaboration between both
400814 - users and applications is the granularity of data access. File
400815 - systems organize information in directories of "files". Sharing
400816 - files is a simple process of placing them on a networked file
400817 - system or simply sending them to a group via electronic mail or
400818 - some other message passing system. This model assumes either that
400819 - files change rarely or that they have single authors or both.
400820 - Sometimes file sharing is augmented or replaced with email
400821 - attachments. ref OF 10 00SY
400823 - ..
400824 - Below, Lee says collective intelligence improves productivity,
400825 - in his paper "Ubiquitous Collaboration". ref SDS 0 03HQ
400827 - Below, Lee seems to describe granular data access as
400828 - addressability and linkable. ref SDS 0 LH5J
400830 - ..
400831 - File sharing reflects collaboration by many people creating a
400832 - common file, rather than submitting contributions which are
400833 - then incorporated by a decision maker; Lee says this
400834 - traditional method is cumbersome.
400836 - ..
400837 - What happens however when we try to use this shared file and email
400838 - approach to collaboratively create documents or accumulate group
400839 - knowledge? Quite simply, a difficult, cumbersome process.
400840 - ref OF 10 00U1

400850 - "Knowledge" needs to be defined in order to assess how "file
400851 - sharing" accumulates it.
400853 - ..
400854 - On 000503 Eric Armstrong decided to avoid using "knowledge,"
400855 - because he recognized that "collaboration" to prepare a
400856 - document, which is useful, may not be an effective usage for
400857 - "knowledge." ref SDS 23 5033

490904 - Version Control Tracks Change History of Word Documents
490907 - Lee says....
490909 - Microsoft Word allows people to exchange and edit documents; a
490910 - user sends a document to another user who edits (or reviews) it
490911 - and sends it back. Word documents contain a change history which
490912 - may be navigated by the first user (the change integrator) and
490913 - individual changes made by the other user may be approved or
490914 - rejected via a GUI interface. ref OF 10 147J
490916 - ..
490917 - How is notice conveyed about changes?
490919 - How is context of proposed changes managed?
490921 - "Context" is an explanation of history and analysis that
490922 - support proposing a change.
490924 - ..
490925 - Suppose somebody proposes inserting an "a" between two
490926 - words, then changes to an "or" then to "and/or". Somebody
490927 - else adds a few words, and somebody else suggests adding a
490928 - paragraph between two words, while another change is
490929 - proposed of deleting the entire mess.
490931 - ..
490932 - How does the GUI approval mechanism in Word, enable the
490933 - author to assess the proposed ideas, and record the
490934 - reasoning for the decision about what is finally said,
490935 - since most likely, it will be different from what everyone
490936 - proposes, but will have been influenced in various ways?
490939 - ..
490940 - Word Advantages for Collaboration
490943 - Integrated:
490945 - The version tracking is completely integrated into the
490946 - document and application, so a user need learn no other tools
490947 - than the additional menu entries provided by the Version
490948 - Control submenu. ref OF 10 005U

Hidden, Lee Iverson, SRI
530701 - ..
530702 - Word Problems
530705 - a. Hidden:
530707 - Since all of the oustanding version history is stored in the
530708 - document itself, many users not familiar with the details of
530709 - the Version Control toolbox are unaware that this content is
530710 - still available in their file. This is a huge information
530711 - security hole and has been anecdotally responsible for
530712 - significant problems when "uncleaned" files are passed on or
530713 - delivered to outsiders. ref OF 10 006T
530715 - Tried an experiment using Word. Created a document, then
530716 - saved it. Made a few changes and saved it again. Found
530717 - "Version" in the File menu.
530719 - ..

590601 - ..
590602 - b. Bloat:
590604 - a. Word documents (especially single user documents) can
590605 - become quite large even when their immediately visible
590606 - content is fairly small, simply because of the change
590607 - history being carried around. ref OF 10 0074
590609 - ..
590610 - b. Email folders fill up with many versions of "shared" Word
590611 - documents as they are passed around for editing or for
590612 - integration of contributions. Since one often wants to
590613 - retain a record of the reasons for changes, these emails
590614 - are often kept in mail folders to provide a trace of the
590615 - document history. This behaviour, which Word docs
590616 - explicitly recommend, can lead to an enormous waste of
590617 - file system resources on Word attachements in mail
590618 - folders. ref OF 10 185K
590620 - ..
590621 - A 46 GB hard disk costs $200 - $300, so storage is not
590622 - a big problem. Transferring a lot of files over and
590623 - over again takes a lot of time. However, hardware is
590624 - getting faster, so this may not be a big issue. If 10
590625 - people are transferring 60 GB several times a day, this
590626 - could add up to maybe an extra hour. The direct lost
590627 - time is not a significant cost, but the crowding out of
590628 - other activity can be.
590630 - ..
590631 - Using email to understand the reasons for making
590632 - changes is not effective, because email is a cursory,
590633 - stream-of-conscous rendering that does not provide
590634 - context necessary to maintain meaning over time, and so
590635 - contributes to meaning drift, explained in POIMS.

730501 - ..
730502 - d. Ad Hoc:
730504 - Clearly people-management skills must be an integral part of
730505 - any attempt to use Word as a basis for collaboration as it
730506 - provides no support for anything other than a single user as
730507 - change integrator. It does provide some ability to enforce
730508 - this strategy by allowing that user to "lock" the document and
730509 - require others to submit "review" comments instead of actual
730510 - edits, but that can quickly become cumbersome as well.
730511 - ref OF 10 I46O
730513 - ..
730514 - Management is inherently "cumbersome" because it requires
730515 - leadership that deals with emotions that resist change and
730516 - accountability, and memory and intellect with strives to
730517 - be accurate and creative.
730519 - ..
730520 - Collaboration requires people skills.
730522 - Incorporating comments into the work is not "cumbersome,"
730523 - it is a core responsibility of engineering and management.

821220 - [On 010623 reviewed version control with Morris.
821221 - ref SDS 79 VO4H
821223 - ..
821224 - RCS maintained the integrity of its version control by requiring
821225 - users to check out files in the repository, modify them and then
821226 - check them back in. While a file was checked out by one user, it
821227 - was unavailable for modification by other developers (locked). In
821228 - many kinds of scenarios, especially software development, a single
821229 - developer may need to change many files in concert before a new
821230 - consistent (and thus check-in-able) state is achieved. Locking all
821231 - of these files while this one developer is attempting to attain
821232 - consistency is untenable as soon as more than two or three
821233 - developers are working on a single project. ref OF 10 CH4M
821235 - ..
821236 - Concurrent Discovery was proposed on 960620 to solve a similar
821237 - problem of people not discovering errors of meaning drift

821265 - There is an ongoing task to assess and approve submissions of

821267 - contributors of changes, inspection of changes for conflicts,
821268 - notice to other contributors for comment on changes, and test
821269 - runs of an updated master set. Conflicts are identified and
821270 - resolved by individuals or groups. The actual master set is
821271 - still unchanged.

821274 - Once changes have been incorporated successfully, a new master
821275 - set version is established, and distributed.

821282 - There is a law of diminishing returns that causes overcrowding
821283 - to reduce productivity. This means multiple programmers
821284 - working on the same code at the same time will be expensive.
821286 - ..
821287 - Isn't this a desire to have 2 or 100 people make simultaneous
821288 - changes that are all compatible. What study shows that
821289 - attempts to make parallel changes using check in and check out
821290 - is more productive than making serial changes on blocks of
821291 - discrete work?
821293 - ..
821294 - CVS solves this problem by removing the locking requirement and
821295 - allowing multiple users to all be editing the same set of files
821296 - simultaneously. Users maintain local versions of the repository
821297 - and make changes as they wish. A user occassionally "updates" his
821298 - local copy by asking CVS to apply those changes made by other
821299 - users to his local copy. This may lead to conflicts, in which a
821300 - section of a file which the user has modified has also been
821301 - modified by someone else. It is then up to the user to resolve
821302 - these conflicts be editing with a text editor. ref OF 10 01RU
821304 - ..
821305 - When checking changes back in to the repository, a user must first
821306 - "update" after which an automatic process detects the changes made
821307 - to a particular file and then sends these to the repository, which
821308 - updates its database. ref OF 10 0136
821310 - Why is proactive problem handling only useful for documents
821311 - created for writing software? SDS enables concurrent
821312 - discovery and correction to save time and money for all work
821313 - activity.

821316 - This sounds like another one of Bill's attempts to
821317 - automatically think for people that only works 80% to 90% of
821318 - the time, and so causes problems 10% to 20% of the time.

821334 - Flexible security:
821336 - The CVS repository is accessible in a number of different ways,
821337 - including via password-protected network channels and

930832 - product today? ref SDS 0 01U3
930834 - ..
930835 - Or, is the proposal for NODAL and CDR intended to draw
930836 - general principles from lessons learned performing software
930837 - programming that can be implemented with technology, skills
930838 - and roles that improve everybody's work? For example, CVS
930839 - provides concurrent version control that ensures work files
930840 - are aligned, so that mistakes are avoided in software
930841 - programming. As noted on 960620 management standards call

930848 - Is this why meetings and calls are cited as targets of the

930852 - Does everybody want to improve their work, or are people
930853 - happy to make a living with the skills they already have?

930856 - Do software engineers, or anybody else, want meetings and
930857 - calls improved, or do people prefer to simply show up and
930858 - work from memory, because that is fast and easy? Is this
930859 - why improving 80% of the work that occurs in meetings and
930860 - calls is proposed under an inocuous heading, rather than
930861 - presented as an opportunity to augment intelligence that can

A50809 - sharing and interchange of hyperlinked documents. Traditionally,
A50810 - this means SGML, HTML and XML, so support for those standards is a
A50811 - minimum. However, the ubiquity of Microsoft Word and the Office

B60607 - thus necessary to be able to insert links between documents (and
B60608 - of course hyperlinks are essential components of HTML and XML in

B80650 - Lee argues....
B80652 - Without this kind of infrastructure in place, the potential for
B80653 - radical enhancement of efficiency and productivity that has always
B80654 - been the promise of networked computing can never be realized. But
B80655 - this will only happen when the barriers to the accumulation of
B80656 - group knowledge and group processes are dismantled. ref OF 7 F13K
B80658 - ..
B80659 - Since the barrier to sharing information comes from biology of
B80660 - self-preservation, i.e., the drive to be safe, it can never be
B80661 - "dismantled," per se. Culture accumulates people into groups
B80662 - that enable some sharing, and this can be exploited within
B80663 - parameters of privacy, security and confidentiality.

B80688 - ..
B80689 - Lee continues....
B80691 - Collaboration generates implicit knowledge through meetings and
B80692 - calls. Good ideas and reasoning for rejecting bad ones are lost
B80693 - to recall unless dialogue and observations are both recorded and
B80694 - integrated into a knowledge base. It is often simple to record and
B80695 - store meetings either with a human note-taker or a digital
B80696 - recording, but without content-based retrieval mechanisms that
B80697 - provide the means to exploit these recordings, and the ability to
B80698 - integrate them into the products that are being developed by the
B80699 - team, it may be of little advantage to do so. ref OF 7 04HS
B80701 - ..
B80702 - Another way to make the same point is that information from
B80703 - meetings, like that from email and other documents must be
B80704 - captured, and converted into useful knowledge, so that when

BA0602 - Versioned and Attributed:
BA0603 - Detailed History of Versions Attribution Builds Trust
BA0605 - If there has been one clear observation made in the both
BA0606 - sociological and computational analysis of what makes
BA0607 - collaborative communities work is that trust is primary. Sharing
BA0608 - knowledge or information is a much more trustable activity if a
BA0609 - user has confidence that it will be used and his/her contribution
BA0610 - will be properly acknowledged. From a system point-of-view,
BA0611 - tracking changes with fine-grained version control and detailed
BA0612 - attribution can be seen as a means to that end. When documents
BA0613 - are more active, such as with computer source code, this
BA0614 - versioning and attribution becomes critical in tracking
BA0615 - enhancements and bugs. ref OF 11 0111

BA0630 - ..
BA0631 - Suppose someone contributes a mistake, as when the CEO tells
BA0632 - people to do thus and so, and it turns to cause earnings and
BA0633 - stock prices to fall. Many CEO's will aver attribution,
BA0634 - because they fear accountability. Software engineers feel the

RDBMS SQL Does Support Security Below Level of Individual Table NODAL
NODAL New Data Base Language Standard Language Independent API
BF0801 - ..
BF0802 - NODAL: An Object-Oriented SQL for Documents
BF0804 - Requirements for NODAL are exactly those which lead to the design
BF0805 - and development of relational database management systems (RDMS)
BF0806 - 20 years ago and the development of SQL 10-15 years ago. There was
BF0807 - a need for an interoperable, shareable, secure resource behind
BF0808 - many kinds of enterprise-level applications. These database
BF0809 - management systems filled that need admirably and SQL became a
BF0810 - standard language for modelling data in RDBMS's and formulating
BF0811 - updates and queries to those databases. ref OF 11 0123
BF0813 - ..
BF0814 - Unfortunately, RDMS systems do not adapt well to the kinds of
BF0815 - graph-like document structures that are represented by modern
BF0816 - markup languages and various forms of knowledge representation
BF0817 - languages (e.g. XTM, RDF/S, DAML+OIL, etc.). They typically do not
BF0818 - handle tree or graph structures well, do not track change
BF0819 - histories for table rows, and do not provide granular and
BF0820 - adaptable control over security and privacy at levels lower than
BF0821 - the individual table. Moreover, their networking models severely
BF0822 - limit the ability to maintain small-scale local caches of data and
BF0823 - operate well when transactions and queries are distributed over a
BF0824 - wide-area network. ref OF 11 0136
BF0826 - ..
BF0827 - Is Oracle creating all of this since they have the data base
BF0828 - concession?
BF0830 - ..
BF0831 - We would like to suggest a new paradigm. NODAL is a language for
BF0832 - data modelling that directly and efficiently supports arbitrarily
BF0833 - complicated typed graph structures with a very small number of
BF0834 - general building blocks. This language is able to express the
BF0835 - internal structure of a wide variety of document formats from
BF0836 - markup languages to multimedia files and will allow applications
BF0837 - and knowledge bases to access and share their contents heedless of
BF0838 - the containing data format. ref OF 11 0148
BF0840 - There are 4 or 5, maybe 6 improvements in RDBMS that NODAL
BF0841 - intends to tackle.
BF0843 - ..
BF0844 - Has any work been done to indicate one or several of these
BF0845 - objectives have been accomplished? Have they all been
BF0846 - accomplished, and are just waiting to be implemented? Is
BF0847 - there a record of experience showing these improvements will
BF0848 - improve productivity and earnings? Has consideration been
BF0849 - given to setting a priority for bringing this capability on
BF0850 - line, based on creating an improvement that has the best
BF0851 - chance of being created and of improving productivity?

BL0602 - Why Not Just XML?
BL0604 - Proponents of XML suggest the XML Schema language is a basis for
BL0605 - supporting NODAL capabilities. They claim that XML is a general
BL0606 - data modelling language and that Document Object Model (DOM)
BL0607 - interfaces to XML database implementations form a general,
BL0608 - interoperable basis for shared document management. If that is
BL0609 - so, then why hasn't this revolution already started? ref OF 11

BL0613 - On 010510 Steve Balmer reported Microsoft is creating XML
BL0614 - capability that will be available in 5 years or so. Balmer
BL0615 - reported Microsoft is investing heavily in the belief that
BL0616 - XML is an important solution for the future. ref SDS 66 8Y8H
BL0618 - ..
BL0619 - The simple answer is that XML has both problems and limitations
BL0620 - that make its applicability to the range of problems we hope to
BL0621 - solve somewhat limited. One of the most fundamental problems is
BL0622 - the lack of separation between the XML data model and the
BL0623 - expressive syntax. This complicates many aspects of the design of
BL0624 - XML-aware applications and libraries to the point that XML-based
BL0625 - specifications have become enormously complicated (e.g. XML
BL0626 - Schema) Pointedly, the XML language does not even have a broadly
BL0627 - recognized data model of its own. The XML Infoset is still an
BL0628 - area of debate and the lack of consensus on its structure makes
BL0629 - the continued development of such things as the DOM itself
BL0630 - increasingly difficult. ref OF 11 X23G
BL0632 - ..
BL0633 - In the NODAL design, we have expressly separated the data
BL0634 - modelling language and APIs from the serialization of said data so
BL0635 - that we may support a wide variety of serializations for the same
BL0636 - document model. In this context, we see XML as a tool we can both
BL0637 - use to build NODAL serializations and protocols and as a
BL0638 - particular target application which may be built using the NODAL
BL0639 - tools. We might thus define an XML Infoset using the NODAL
BL0640 - language and use the client APIs as a basis for a DOM
BL0641 - implementation. ref OF 11 011R
