Hello.
* Background:
I've started looking into ASN.1, for incorporation into some project
I've worked with SGML and XML, and I've not been terribly satisfied with
XML Schemas, honestly -- and I am not looking to start a "flame war" about
it, but maybe it will serve to explain the background of this message.
I've not been terribly satisfied with XML Schemas, myself, and I am quite
satisfied, with what I'm seeing about (and of) ASN.1[1].
I'd noticed, also, that there are some standards, available from the
ITU[2], for tranlsation-or-something between ASN.1 and XML/XML-Schema
syntaxes.
Now, I don't know if XMI has "anything, directly technical, to do with
any of this" -- though, of course, it seems that XMI might accomplish
an end simliar to that of ASN.1. (I've not read much of anything about
XMI, but I think I can guess the intention of it -- and yet, I cannot
guess about how it plays in with-or-beside SOAP; I saw XML mentioned,
in one of the UML 2.0 standards drafts; it seemed worth mentioning,
here, also).
* Question:
Has anyone looked at any of the stuff (standards and/or tools) for
managign XML<->ASN.1 "translation" work?
If so: What has anyone thought of it?
* Motivation
Perhaps ASN.1<->XML "stuff" could ever be pertinent for the Eclipse
project - "off in the R&D wing of things, for now", heh.
(and beside that: I'll have to "dig" into some more research about
such standards & tools, myself. It will be easier, probably, if I know
of anyone who's found such standards/tools to be useful, now or in a
clear-enough prospective end)

[1] "FWIW", there is one /very well written/ book about ASN.1, freely
avaialable for download, at:
http://www.oss.com/asn1/dubuisson.html
It was written, originally, in French, I think; the version,
available at the page referenced, above, was translated into
English, and the translation was quite well done. Regardless of
choices of national language, the book is quite thoroughly
descrptive about ASN.1, regarding: the basis and motivation, for
the development of ASN.1; the language and the specific syntax of
ASN.1; some example-type uses of ASN.1, "to get the reader going,
by".
(Yes, this is not an advertisement; I just wanted to be thorough, heh.)
[2] ASN.1 standards:
http://www.itu.int/ITU-T/studygroups/com07/asn1recs.html
http://www.itu.int/ITU-T/studygroups/com17/languages/
...most, if not all of which, are available, freely, for download.
(The ITU, thus far, has liked to charge fees, for download of some
other standards of theirs; it looks like they've put ASN.1 "in the
clear", though.)

Sean,
Oh my goodness, just what the world needs. Thousands upon thousands of
pages of specification to define more standard data exchange
mechanisms. This certainly does look to overlap heavily with other
standards efforts. After all, who isn't claiming this:
ASN.1, or Abstract Syntax Notation One, is an International
Standards Organization (ISO) data representation format used to
achieve interoperability between platforms.
Certainly XML, XMI, and Corba will make this claim too. Do you know how
this particular data representation format defined by a standards body
to facility interoperability, claims to be superior to all the others?

ASN.1 has been around for many moons (circa 1984) . Its main plus point is
its streamlined representation and therefore its efficiency of transport in
low bandwidth systems (as opposed to big xml structures and the relative
inefficiency of web services etc!).
It is generally encoded into octets using BER (or PER) encoding and then
transmitted. One example of its use is to facilitate the data exchange
between Z39.50 search clients and remote servers using binary encoded search
strings and returning binary encoded search results.
So it could claim to be superior in efficiency terms :)
