1 Introduction

This document describes a file format that describes detection of file formats, e.g. by filename extension.

1.1 Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

2 File Structure / Example

[1.3.6.1.4.1.37476.3.1.5.2] -- Standard OID Illegality Rule Definition File -- by Daniel Marschall and Olivier Dubuisson -- Revision: 7 July 2024 -- SYNTAX: -- -- comment : comments are also allowed after a rule definition -- 2.999.(11-).0 : the arc values 11 and below are illegal -- 2.999.(11+).0 : the arc values 11 and above are illegal -- 2.999.(1-5).0 : the arc values 1 to 5 are illegal -- 2.999.(!3).0 : only arc 3 is valid, all others are invalid -- (added in version 2) -- 2.999.* : * is equal to (0+). Usually used for leaf OIDs 0.(10+) -- itu, currently max 9 0.4.(1+) -- 0.4.0 is the only identified organization 1.1.3.* -- Reserved for ISO/IEC 9834-3 1.2.6 -- was 1.3.6 meant? 1.2.826.1004 -- The correct OID is 1.2.826.0.1004

3 Ideas for Future Developments ("Format 3.0")

- JSON Format - Better notation for ranges, with multiple components. - Differentiate between "illegal" (must not exist) and "must-not- create" (may exist, but must not create). - Machine-readable description instead of a comment. - Include/Exclude lines. You start from top to bottom and Marschall [Page 3]
VTS/WF STD. 10 Illegal OID Definition File 11 September 2024 include/exclude stuff, and at the end you have an answer if the OID is illegal. - For frozen OIDs, we must allow that a single arc is frozen (non- existing OIDs are illegal), but the existing OIDs may create children.

4 Security Considerations

None

5 RA Considerations

OID: 1.3.6.1.4.1.37476.3.1.5 WEID: weid:pen:SX0-3-1-5-3 ASN1: { iso(1) identified-organization(3) dod(6) internet(1) private(4) enterprise(1) 37476 specifications(3) fileformat(1) oid-illegality-rules(5) } IRI: /.../Specifications/FileFormat/OID-Illegality-Rules Children: + v1(1), IRI Version1 + v2(2), IRI Version2
