Hvad er BDOB-filformatet?
En .bdob-fil er et NATO Binary Binding Data Object. Den binder metadata, oftest en fortrolighedsmærkning, til et dataobjekt, så objektets følsomhed kan spores, når det flyttes mellem partnere i informationsudveksling. Formatet stammer fra NATO Standardization Office og er defineret i Allied Data Publication ADatP-4778, som er Metadata Binding-mekanismen bag STANAG 4778. IANA registrerer den under medietypen application/vnd.nato.bindingdataobject+cbor.
En .bdob-fil gemmer bindingen i .cbor, Concise Binary Object Representation beskrevet i RFC 8949. Det gør den til den binære søskende til den XML-baserede .bdo-fil, som bærer den samme bindingsmodel som tekst. Filen indeholder metadataene og en reference til det dataobjekt, den beskriver, snarere end selve indholdet (payload), så den forbliver lille. En binding kan også indeholde et COSE-element, så den kan signeres digitalt for autentificering og integritet.
Du vil hovedsageligt støde på .bdob-filer i forsvars- og regeringssystemer, der følger Data Centric Security-tilgangen, hvor hver del af de delte data rejser med en maskinlæsbar mærkning.
Sikkerhed og tryghed
RISIKO: LOWA .bdob file is passive data. The IANA registration states it carries no active or executable content, so opening one cannot run code. The main caution is that it may hold a confidentiality label indicating sensitive or classified material, and any COSE signature should be validated before trusting the binding. Referenced data objects live outside the file and must be resolved separately.
Formatdetaljer
kort fortalt- Generic renamed CBOR data - Some non-NATO applications reuse a .bdob extension informally for arbitrary CBOR-serialized data objects, but that is not a registered format.

dyb specifikation| Encoding | Concise Binary Object Representation (CBOR), per IETF RFC 8949 |
| Byte order | Big-endian (CBOR head/length fields are network byte order) |
| Container | CBOR data item, optionally wrapped in a COSE (RFC 8152 / RFC 9052) structure for signing |
| Compression | None (CBOR is a compact binary encoding, not a compressed container) |
| Encryption | Not encrypted by default; the binding may carry a COSE-tagged element for authentication and integrity, and referenced data objects can be protected separately |
| Integrity | Optional COSE_Sign / COSE_Mac elements provide digital signatures and integrity protection over the binding |
| Structure | A binding data object associates one or more metadata items (chiefly a STANAG 4774 confidentiality label) with a referenced data object. The CBOR profile encodes the same binding model as the XML .bdo profile, holding the metadata, a reference to the bound data object, and optional signature material. |
| Platforms | Cross-platform |
| Notes | BDOB is the binary sibling of the XML-based .bdo file. Both are profiles of the NATO ADatP-4778 Metadata Binding Mechanism, used within Data Centric Security (DCS) to bind confidentiality metadata to data throughout its lifecycle across information-sharing partners. |
| Typical size | Small, from a few hundred bytes to a few kilobytes, since it holds metadata and references rather than the payload data itself |

Hvad er en BDOB-fil?
.bdo.Hvordan åbner jeg en BDOB-fil?
.cbor-navn og kør en dekoder såsom Pythons cbor2.tool, eller indsæt dens hex-bytes i cbor.me-webviseren for at se strukturen som læsbar tekst.Er en BDOB-fil det samme som en CBOR-fil?
.bdob er en CBOR-strøm, men filtypen signalerer, at dens indhold følger NATO ADatP-4778-bindingsprofilen. Enhver CBOR-dekoder kan læse de rå bytes, men kun ADatP-4778-bevidst software fortolker bindingsfelterne korrekt.Hvad er forskellen mellem .bdo og .bdob?
.bdo-fil gemmer den som XML-tekst, mens en .bdob gemmer den som kompakt binær CBOR. Den binære form er mindre og hurtigere at parse, men ikke menneskeligt læsbar uden en dekoder.
