1. Introduction
This document defines an ontology that describes the specifications
published by the RFC Editor, together with ancillary documents like
errata and RFC series.
This effort is the continuation of the RFC-Prolog database that was
described in one of the position papers presented at the IAB Workshop
on Analyzing IETF Data (AID) [RFC9307]. The schema in that database
was simplified and reformulated as an ontology.
2. The RFC Ontology
The RFC Ontology extends the Bibliographic Ontology [BIBO] and reuse
elements from the Friend of a friend [FOAF] and DCMI Metadata Terms
[DCTERMS] ontologies.

Appendix A. Implementation
An implementation of the RFC ontology using the programming language
Ergo [ErgoAI] is provided.
The "rfcs.ergo" file contains the list of all RFCs, BCPs, STDs, and
FYIs.
The following example shows an RFC metadata encoded in Ergo:

Comments on some non-obvious encoding:
* "terms#creator" contains the set of authors. This uses a Skolem
symbol to represents the fact that we do not have a resource for
the person, but we want to define it only once (equivalent to a
blank node). The mathematically inclined can think of this as an
existential quantifier ("there exists a person named…").
* "terms#editor", not present in this example, would contain the set
of editors.
* "bibo#authorList" contains the ordered list of all authors and
editors.
* "rfc#normativelyReferences" or "rfc#informativeReferences" are
difficult to parse in RFCs that were not published in xml2rfc
format, so this is currently work in progress.
The following example shows a BCP encoded in Ergo:
\"https://www.rfc-editor.org/info/bcp0003":rfc#Bcp
[ rfc#number -> 3
, bibo#hasPart ->
{ \"https://www.rfc-editor.org/info/rfc1915"
}
].
STD and FYI are encoded similarly, substituting respectively
"rfc#Std" and "rfc#Fyi" to "rfc#Bcp".
The "errata.flr" file contains the list of all Errata.
The following example shows an Errata encoded in Ergo:
Petit-Huguenin Expires 21 January 2025 [Page 26]
Internet-Draft An Ontology for RFCs July 2024
\"https://www.rfc-editor.org/errata/eid5866":rfc#Errata
[ rfc#id -> 5866
, rfc#corrects -> \"https://www.rfc-editor.org/info/rfc0005":rfc#Rfc
, rfc#type -> rfc#editorial
, rfc#status -> rfc#verified
, rfc#reportedBy -> \#:foaf#Person[foaf#name -> 'Martin Thomson']
, rfc#reportedOn -> "2019-09-26"^^\date
, rfc#processedBy -> \#:foaf#Person[foaf#name -> 'Benjamin Kaduk']
, rfc#processedOn -> "2019-09-26"^^\date
].
The git repository also contains a [Zotero] importer for the same
"rfc-index.xml" file that is used to build the "rfcs.flr" file. The
simplest way to install it is to create a symbolic link for the "RFC-
Index.js" file in the subdirectory "translators" of the "~/.zotero"
directory.
A.1. Examples of Queries
The examples that follow can be executed in the Ergo REPL ("runergo"
or "runergo.bat").
The Flora-2 REPL can be either run from the local machine or from
Docker:
docker build --build-arg uid=$(id -u) -t runergo:latest . \
&& docker run --rm -it -u $(id -u):$(id -g) -v $(pwd):/ergo \
runergo
The files must be loaded after starting the REPL:
[schema,+rfcs,+errata].
Note that loading the files should take a minute the first time, but
around one second after that. Queries should not take more than a
few hundred milliseconds to run.
Listing all the April Fools's Day RFCS:
?:rfc#Rfc[rfc#number -> ?rfc, rfc#date -> ?_d],
?_d[endsWith('-04-01')]@\btp.
Listing all the RFCs that cites RFC 5234, normatively or
informatively:
?_abnf:rfc#Rfc[rfc#number -> 5234],
?:rfc#Rfc[bibo#cites -> ?_abnf,
rfc#number -> ?rfc, terms#title -> ?title].

Internet-Draft An Ontology for RFCs July 2024
Identify all the RFCs that are descendants of a particular RFC by
traversing the set of RFC update and obsolete relationships. Save
that code in a file named "desc.ergo", then load it in the REPL with
[schema,+rfcs,+desc].. Then descendant(, ?rfc). will
return the descendants.
descendant(?number, ?rfc) :-
?_rfc:rfc#Rfc[rfc#number -> ?number],
descendant_1(?_rfc, ?rfc).
descendant_1(?x, ?z) :-
?z:rfc#Rfc[rfc#updates -> ?x].
descendant_1(?x, ?z) :-
?z:rfc#Rfc[rfc#obsoletes -> ?x].
descendant_1(?x, ?z) :-
?y:rfc#Rfc[rfc#updates -> ?x],
descendant_1(?y, ?z).
descendant_1(?x, ?z) :-
?y:rfc#Rfc[rfc#obsoletes -> ?x],
descendant_1(?y, ?z).
Finding the transitive closure of normative references to an RFC,
i.e., all RFCs that normatively reference that RFC or an RFC already
in the list. Save that code in a file named "tran.ergo", then load
it in the REPL with [schema,+rfcs,+tran].. Then
transitive_closure(, ?rfc). will return the transitive
closure.
transitive_closure(?number, ?rfc) :-
?_rfc:rfc#Rfc[rfc#number -> ?number],
transitive_closure_1(?_rfc, ?rfc).
transitive_closure_1(?x, ?z) :-
?z:rfc#Rfc[rfc#normativelyReferences -> ?x].
transitive_closure_1(?x, ?z) :-
?y:rfc#Rfc[rfc#normativelyReferences -> ?x],
transitive_closure_1(?y, ?z).
More examples will be provided in future versions of this draft.
Suggestions are welcome.
A.2. Distribution
The files are distributed as a git repository that can be cloned with
the following command:
git clone git://shalmaneser.org/VejlapAknul1 rfc-ontology-ergo
Petit-Huguenin Expires 21 January 2025 [Page 28]
Internet-Draft An Ontology for RFCs July 2024
This git repository is mirrored in various locations over the world,
with the GPS coordinates in decimal degrees of all these locations
stored in the DNS as a TXT resource record. The "dig +dnssec txt
shalmaneser.org" command can be used to find these locations and
substitute the closest subdomain in the git URL above.
The git repository is updated most Mondays before 23:59:59 UTC with a
new commit that covers new RFCs, Errata, or changes in status. The
date of the next planned update is added of the comment of each
commit.
The "update" script that is used to update the files is distributed
in the git repository, so they these files can be updated in case the
current maintainer is unable to do so. The list of tools to install
prior to running the script is in that script.
The code in that repository is licensed under an AGPL3+ license.
