Rev Interoperability Discussion Group

As I mentioned in my presentation in Malta at ERC 2004, I've put
together a new discussion group at Yahoo to focus on issues and
solutions for developers using Rev to make plugins and other components
for use in multiple applications.
The Rev Interoperability group is at:
I've uploaded two files there:
- EMCI.txt - A first (and rough) draft of a specification to
help such components play nice with others.
- lib4WSHELL - An example library shell which can be used as
a template for building your own libraries, with a few
conveniences built in. This shell is also available in
If you build libraries and other components for use by other Rev
developers, or have been itching to do so, this discussion group may be
helpful. Please feel free to rip apart the current rough draft spec so
we can all contribute to revising it into something that's truly useful
Here's the introduction section for the draft 001 to give you a feel for
what that group's discussion is focused on:
As the Transcript development community grows we can expect many new
innovative solutions coming from its members. These include:
Stack files that hold scripts which can be called from throughout
the message path, initialized with "start using".
Objects or groups of objects which have a specific purpose or
function, such as a table widget or FTP settings dialog, useful
across multiple projects.
Prefabricated collections of objects which work together to
provide the basis for a complete software application, such
as a shell for a slide show viewer or a system utility.
As the variety of these things grows issues of interoperability are
introduced, such as name space conflicts among handlers or objects. In
addition to minimizing errors, there is an opportunity to provide easier
integration of elements from different third parties.
This initiative proposes a set of conventions which aim to serve both
goals, minimizing the risk of introducing errors when integrating
elements, and exploring ways to make it simpler to use such elements.
Much of what is needed for that goal could be described generically as
"metadata", additional information bound to the objects in question but
which do not directly affect performance of those objects.
The Dublin Core Metadata Initiatibe (DCMI) is a consortium effort to
facilitate exchange of documents. Given that the goals of the DCMI and
this initiative are in many ways very similar to ours, and that the DCMI
working group has already expended tremendous investment in defining
metadata needs for such purposes, this initiative aims to use DMCI
nomenclature and conventions whenever practical.
To reinforce this deference to the DCMI project and as a tip-of-the-hat
to the company that produces Transcript and Revolution (Runtime
Revolution Ltd. of Edinburgh), this project is given the lighthearted
name of "Edinburgh Core Metadata Initiative" ("ECMI").
