Brian,

A couple of resources that may be of interest:

ASN1 to XSD tool: http://asn1.elibel.tm.fr/xsdasn1/ 

A technote, I worked on sometime ago about WSDL and ASN.1:

http://www.lib.ox.ac.uk/jafer/wsdl/wsdl-asn1.html (and a possible

application using z39.50 a search/retrieve protocol which uses BER

http://www.lib.ox.ac.uk/jafer/ez3950/ez3950.html)

A reader at XML-DEV suggested that I cross-post this message to you 

here.  I have only begun to read the information about ebXML, but it 

does appear that my message may be of some interest to you.

Thank you.

XML-DEV...

Hello!  I am new to XML, and have just discovered XML-DEV.  I am

writing to you now to request comments, suggestions, and

recommendations on some work I am doing.  You could say that I am also

looking for the problem that fits my solution.  :)

I have written some software that converts protocol data from the

binary BER format to XML.  BER is a popular format for encoding

protocols that are defined using ASN.1.

The conversion process is protocol-specific.  The software applies

element names and data formats as per the ASN.1 protocol definition.

The software is capable of handling several of the current protocols

defined by ASN.1, and that support can be easily extended to include

many others.  Popular protocols such as SNMP, LDAP, MAP, TCAP, and

X.509 are already supported.

Most of these protocols are easy 'base' protocols.  But the software

is also able to support the massive and complex GSM/UMTS MAP protocol,

where it must perform the MAP conversion based on information is takes

from a TCAP base.  I hope to support X.509 certificate extensions in a

similar manner in the future.

Please see http://www.holmespun.biz/berasno/ for details and examples.

I am currently working on the XML to BER conversion functionality.  I

would like to find a partner or a sponsor... or at least hear some

words of encouragement... before I spend too much more of my time.

Obviously, I am not sure how useful the functionality is, but it seems

to be unique, so I thought I would write to ask for your opinions.

What do you think of the functionality in general?

Do you know of anyone else working on this sort of functionality?

Do you know of any commercial use for this functionality?

What do you think of my implementation of it specifically?

How could the resulting XML be improved?

Are there other protocols that you would like to see supported?

Do you have some data that you would like to see converted?

Please feel free to forward this message to anyone else you think

might be interested.

Thank you.

...Brian
