OT: Looking for a protocol

OT: Looking for a protocol

[Steve]

It's off topic, but I know smart guys hang out on CLA so I'll ask anyway.

I'm looking for a standard in which XML metadata is used to describe the 
structure of binary data.

I want to send packets of binary data across TCP/IP with each packet 
preceded by a globally unique identifier (GUID) that identifies 
corresponding XML metadata.  If the receiver does not already have the 
metadata, it can be requested from a server.  Otherwise the receiver uses 
the metadata to interpret the binary data.

It sounds so simple, someone has probably already done it.  Is there a 
standard?

I did some searching and came up empty.

TIA,
Steve

To me this seems like a problem susceptible to ASN.1, but that is my bias.

Well, call me stupid - but what the heck is ASN.1?

It's very widely used in telecom.

It is also used to define the X.500 standards, and thus the
ubiquitous X.509 public key certificates.

It is particularly designed for specifying information that is
agnostic to the bit ordering habits of particular computer
architectures.

One can think of it as XML without the wasted space.

Oh well, why use Ada with all this unnecessary
repetitive syntax.

Nevertheless, to use an ASN.1 data stream with  XML,
use a NOTATION and then NDATA sections.

One can also think of ASN.1 as requiring a very well
working environment, and also additional software for
debugging, unless you are satisfied with deciphering
bit combinations in a debugging situation.

Thank you,
I'll have a look.

The repetitive syntax in Ada is to promote human understanding.
ASN.1 is a tightly specified machine representation, for which
excessive verbiage accomplishes nothing.

I think of all protocol implementation as being of that nature.
