# Fetch RFC document
item = RelatonIetf::IetfBibliography.get 'IETF RFC 8341'
[relaton-ietf] (IETF RFC 8341) Fetching from Relaton repository ...
[relaton-ietf] (IETF RFC 8341) Found: `RFC 8341`
=> #<RelatonIetf::IetfBibliographicItem:0x007fd1875e7f58
...

# Fetch Internet-Draft document
RelatonIetf::IetfBibliography.get 'IETF I-D.draft-abarth-cake-01'
[relaton-ietf] (IETF I-D.draft-abarth-cake-01) Fetching from Relaton repository ...
[relaton-ietf] (IETF I-D.draft-abarth-cake-01) Found: `draft-abarth-cake-01`
=> #<RelatonIetf::IetfBibliographicItem:0x00007fdd129bbeb8

Serialization

item.to_xml
=> "<bibitem id="RFC8341" type="standard" schema-version="v1.2.1">
      <fetched>2022-12-03</fetched>
      <title type="main" format="text/plain">Network Configuration Access Control Model</title>
      <uri type="src">https://www.rfc-editor.org/info/rfc8341</uri>
      <docidentifier type="IETF" primary="true">RFC 8341</docidentifier>
      ....
    </bibitem>"

With bibdata: true option XML output is wrapped with bibdata element and ext element added.

item.to_xml bibdata: true
=> "<bibdata type="standard" schema-version="v1.2.1">
      <fetched>2022-12-03</fetched>
      <title type="main" format="text/plain">Network Configuration Access Control Model</title>
      <uri type="src">https://www.rfc-editor.org/info/rfc8341</uri>
      <docidentifier type="IETF" primary="true">RFC 8341</docidentifier>
      <docidentifier type="DOI">10.17487/RFC8341</docidentifier>
      ...
      <ext schema-version="v1.0.1">
        <editorialgroup>
          <committee>netconf</committee>
        </editorialgroup>
      </ext>
    </bibdata>"

Typed links

IETF documents may have src, xml, and doi link types.

src - web publication
xml - BibXML publication
doi - DOI reference

item.link
=> [#<RelatonBib::TypedUri:0x00007fe8b287a120 @content=#<Addressable::URI:0x7e4 URI:https://raw.githubusercontent.com/relaton/relaton-data-rfcs/main/data/reference.RFC.8341.xml>, @type="xml">,
 #<RelatonBib::TypedUri:0x00007fe8b2237ec0 @content=#<Addressable::URI:0x7f8 URI:https://www.rfc-editor.org/info/rfc8341>, @type="src">]

Parse a file locally

item = Relaton::Provider::Ietf.from_rfcxml File.read("spec/examples/rfc.xml")
=> #<RelatonIetf::IetfBibliographicItem:0x007fa8cda79ab8
...

Create bibliographic item from YAML

hash = YAML.load_file 'spec/examples/ietf_bib_item.yml'
=> {"id"=>"RFC 8341",
...

RelatonIetf::IetfBibliographicItem.from_hash hash
=> #<RelatonIetf::IetfBibliographicItem:0x007f9a929dde40
...

Fetch data

There are IETF datasets that can be converted into RelatonXML/BibXML/BibYAML formats:

ietf-rfcsubseries - https://www.rfc-editor.org/rfc-index.xml (<bcp-entry>, <fyi-entry>, <std-entry>)
ietf-internet-drafts - convert files from local directory ./bibxml-ids. Use rsync -avcizxL rsync.ietf.org::bibxml-ids ./bibxml-ids command to fetch the files.
ietf-rfc-entries - https://www.rfc-editor.org/rfc-index.xml (<rfc-entry>)

The method RelatonIetf::DataFetcher.fetch(source, output: "data", format: "yaml") converts all the documents from the dataset and saves them to the ./data folder in YAML format.

Arguments:

source - dataset name (ietf-rfcsubseries or ietf-internet-drafts)
output - folder to save documents (default './data').
format - the format in which the documents are saved. Possible formats are: yaml, xml, bibxml (default yaml).
