Doug asked me to do something useful, maybe a list of terms and
definitions. I have learned that this means Ontology - everyone refers
to the exact same item in the exact same context by the exact same name.
Using this concept In a DKR node map, if an information item has an id
that is unique in a unique namespace then the content can be found very
simply.
The basis of any set of definitions/standards is
www.isi.edu/in-notes/rfc2119.txt
where we begin wilh use of the words must, must not, required, shall,
shall not, should, should not, recommended, may, and optional. As we
describe this implement we are working on, let's agree on those terms
for now, at least.
Currently the terms transcode and translate have been used, sometimes
leaving the audience balked at what that may mean.
I think we can use the term transcode for almost every operation of this
system except for operations that involve actual translation from one
ethnic language to another, like from Amercan English to Japanese. The
process of translation usually infers some drift of content as it moves
from one context to another.
Transcoding, at its simplest, means faithfull substition of one encoding
form for another with complete presevation of the content, For example
transcoding is the operation of converting a data stream from UTF-8 to
UTF-16 with no information loss. A more general form of transfoding is
to add or change some part of the object for the purpose of
compatibility between processes while completely preserving all content.
When an item is submitted to the DKR, or read from the DKR, some sort of
change will happen to the item. Even if this change is just an update of
some attribute, or if the change is conversion from text to speech, we
can safely call this change a transcode step. Of course each step in the
transcoding must be completely and unambigiously specified.
As a sidelight: Sending content to the DKR can be visualized as a
translation process, moving an information item from its location of
construction, the OHS, to its location of storage, the DKR. Just imagine
a geometric form that identifies the item as it takes its place in the
existng DKR node map.
Thanks and Best Regards,
Joe
