Abstract

A mechanism is described which greatly extends the set of document transformations which can occur in a mail system. This mechanism makes document transforms available which would otherwise not be available.

Multistage Document Transforms

      A mechanism is described which greatly extends the set of
document transformations which can occur in a mail system. This
mechanism makes document transforms available which would otherwise
not be available.

      Mail systems and applications often require support for a
multiplicity of document content architectures. Said support refers
to being able to convert between a set of document formats so that
foreign document content architectures can be converted into document
content architectures understood by the receiving applications. The
terminology used to describe this support is document transforms.
Document transforms are required for allowing successful
communication of documents between unlike systems. A heterogeneous
environment containing many varieties of applications could not
communicate with each other without document transforms unless they
all emitted and operated on the same document format(s), a situation
which seldom occurs. An invention is needed which can expand the set
of supported document transforms without forcing the burden of
implementing new transform code.

      The present invention shall be described as being particular to
the OfficeVision*/2 (OV/2) product, but it is expected that those
skilled in the art will recognize that application to OV/2 is one
embodiment of the present invention. This invention allows OV/2 to
provide transforms for situations in which explicit transforms do not
exist. If a transform from document format A to document format B
does not exist, this invention describes a mechanism for transforming
A to C and then C to B so that the end result is achieved.
In fact, ther...
