QUICK ANSWER
Is it possible to convert BDOB to CBOR?
No - not a direct conversion.

A .bdob file is a NATO Binding Data Object encoded in CBOR (its MIME type is application/vnd.nato.bindingdataobject+cbor). It already IS CBOR, so "converting" to .cbor just means relabelling the same bytes. If you want the raw CBOR, copy or rename the file; any CBOR tool can already read it.

Why convert BDOB to CBOR?

The .bdob format is defined by ADatP-4778 as the CBOR-based variant of a Binding Data Object - a binary alternative to the XML .BDO. Since it is literally stored as Concise Binary Object Representation, there is no meaningful .bdob-to-.cbor transformation, only a change of filename or label.

How to convert BDOB to CBOR

Rename the file FREE

Copy object.bdob to object.cbor. The bytes are unchanged because .bdob already uses the CBOR encoding.

Read it with a CBOR library OPEN-SOURCE

Point any CBOR parser (Python cbor2, JavaScript cbor, or cbor.io tools) at the .bdob file - it decodes directly with no conversion step.

Decode to JSON with cbor2diag OPEN-SOURCE

If you want a readable view, run a CBOR-to-diagnostic/JSON tool on the .bdob to inspect the structure without altering the original file.

Quality & what to watch

  • .bdob and a generic .cbor file are the same encoding; only the NATO-specific MIME type and intended use differ.
  • Renaming to .cbor discards the ADatP-4778 context, so downstream systems may no longer recognise it as a Binding Data Object.
  • Because it is binary, a .bdob won't open usefully in a text editor - use a CBOR-aware tool to see its contents.

Frequently asked questions

Isn't .bdob just CBOR already?
Yes. It is a NATO Binding Data Object stored in CBOR, with the media type application/vnd.nato.bindingdataobject+cbor.
Can a normal CBOR tool open a .bdob?
Yes. Standard CBOR parsers read it directly because the underlying encoding is plain CBOR.
Do I lose anything by renaming to .cbor?
The bytes are identical, but you drop the NATO MIME type and ADatP-4778 labelling, so its defence-format context is no longer signalled.
How do I see what's inside?
Use a CBOR diagnostic or CBOR-to-JSON tool; a plain text editor will only show binary gibberish.
