The Open Meeting system was initially designed and implemented in fall,
1994, to support an on-line meeting, in which several thousand United
States government workers conducted virtual discussions of recommended
changes in government operations and performance standards. At the
system's core is a persistent object database, which coupled to a task
engine, supports email and web servers. These present messages and
pages, with content generated on-the-fly by the database, in response to
users' inputs through queries, remote commands or interactive forms.
Inputs can include users' comments which are added to the database and
reconfigured as threaded conversations or annotation overlays. The
recommendations for discussion had been prepared by the National
Performance Review (NPR),[4] a unit in the Office of United States
Vice-President Al Gore, with the mission of "reinventing government."
It believed a large scale on-line meeting would
- Increase the visibility and support for these recommendations;
- Enhance their prestige through association with new technology;
- Gather reports on promising practices in line with them;
- Bypass organizational boundaries that keep employees in
different organization from discussing common work problems;
- Overcome geographical barriers that confine discussions on
government to the capital;
- Demonstrate the possibility of on-line/ electronic governance.
As the last point suggests, in the NPR
view, government workers comprised a community whose opinion needed to
be articulated and mobilized. The NPR project team
for the meeting was guided
by the metaphor of a New England town meeting, where any member can of
the community can
speak to issues of common concern. It envisioned an on-line
environment analogous to a town hall, that would include chat rooms for
an assembly hall, committee rooms and water cooler.
The trajectory toward a community activation system changed with the
involvement of the Open Meeting developers, members of an MIT group,
whose research concerned intelligent networks that route and enhance
messages, based on understanding of their contents and the organizations
through which they flow. At the time, the research group was planning a
web based system that would manage public participation in government
inquiries on proposed changes in regulations. The initial plan called
for interested parties to attach their views as annotations to the
proposals, differentiated according to the types of comments being made,
e.g., question, statement of support. Officials could then retrieve
these comments by target and type from a textbase of review documents,
using the system, in effect, as an annotation server. Alternatively,
the comments on a document could be routed directed to officials whose
profiles indicated their in that document. By enabling the public and
officials to receive and reply to each other's comments, the system
would support virtual discussions composed of threads of typed comments.
Through the prism of this plan, the federal workers appeared like
individual stakeholders responding to inquiries on proposed changes in
regulations affecting their individual interests, work rules and
performance standards. They were primarily sources of information about
the benefits, feasibility and acceptability of the proposals.
To encourage broad participation and knowledge sharing, regardless of
organizational differences, we consequently advised that the meeting
focus on eleven NPR reports, each of which concerned reinventing an
operating system, like human program development or information
management, found in all departments and agencies and subject to the
same rules and standards. These could provide common grounds for
discussions across organizational boundaries, but recommendations for a
specific department were unlikely to draw workers from other departments
into a discussion. We also advised dropping the town hall format for
several reasons:
- a reluctance to assume the participants already
recognized themselves as a community;
- the desired dispersion of participants over time zones made
asynchronous communications more feasible;
- chatrooms, MUDs and MOOs would not scale for the desired number of
participants;
- email would not support the GUIs which could suggest a town hall
setting, and email was mandatory because relatively few workers then had
web browsers.
The group proposed instead a system similar to the public comment system
sketched above, as an application layer for Comlink, an enhanced document
distribution system, developed primarily by Mallery and used for the
indexing, publication and retrieval of White House electronic releases
on the Internet.[5]. The principal features and functionalities of
the resulting system included
- An extensible, persistent object database whose instances
include texts and users. The text instances include hypertext links and
indices, and so support extension of an initial textbase configurable as
hypertext; arbitrarily constrained, on-the-fly construction of local
hypertext; and views of the hypertext, restricted by arbitrary indices,
like quality ratings, security classifications, etc. The user objects
can include slots for interests and preferences, enabling subscription
to and routing of texts.
- Dynamically generated web pages which facilitate
representation and navigation of the online discussions and
collaborations. Regions of the resulting hypertext can be isolated;
pointers to comments and annotations descending from an initial text can
be displayed in an outline or tree, each with an icon for the type of
the comment. This permits both overviews of the link structure and
direct access to those comments which interest the user.
- Interactive form processing to support user queries and
comments, hypertext traversal, and search interfaces for retrieval by
indices.
- Message threading that constrains input according to
conversation or discourse grammars. Grammar means a set of (context
sensitive) rules that specify the types of texts or comments that can be
linked to another text or comment, according to its type. By type, we
mean remarks that constitute recognizable moves or roles in discourse or
communicative interaction, e.g., remark types in a debate include claim,
challenge, rebuttal, question, answer, etc. A grammar thus represents a
procedural order, often with possible branching.
- Subscription to arbitrary node: A retrieved text was wrapped
in a form which could be used to request emailing of comments
that are later attached to the text or any of its descendants. Since
the particular text as a database object is automatically identified in
the form, subscription is transparent: The user does not have to
specify the node.
- Moderator tools enabling submissions to be handled
before being posted to public view. These include a) a moderator's view,
b) virtual queues for routing submissions on a topic to its moderator,
c) forms for attaching ratings and view restrictions, c) form letters
accepting and rejecting submissions. With these, the Open Meeting can
support moderated as well as unmoderated online conferences.
