Notes:

• <reference> element:
  • The anchor attribute (which is used to create the citation tag) of the <reference> element should use the following default in bibxml-service entries:
    • anchor=“RFCNNNN”
  • The target attribute:
    • Should use the following URL construction:
      • RFC: https://www.rfc-editor.org/info/rfcNNNN
• <title> element:
  • ASCII equivalents (e.g., double quotes, hyphens) are to be used for punctuation (e.g., to replace smart quotes and em dashes).
• <author> element:
  • non-ASCII in <author> attributes is okay.
  • Note that RFC entries do not have <organization> elements because the API (rfc-index.xml) does not provide that data.
• <date> element:
  • RFCs (except for April 1 RFCs) have month and year attributes only.
  • April 1 RFCs must have day=“1”, month=“April”, and year attributes specified.
• <seriesInfo> element:
  • Although <seriesInfo> can now go into the <front> element, the RPC follows received guidance to keep it out of <front>.
  • RFCs have two <seriesInfo> elements:
    • <seriesInfo name=“RFC” value=“NNNN”/>
    • <seriesInfo name=“DOI” value=“10.17487/RFCNNNN”/>
• <format> element:
  • Although originally provided by tools.ietf.org bibxml, this element should not be used. See the discussion.
• Numbering:
  • RFCs have padding of leading zeros for numbers used in the value attribute of DOI <seriesInfo>, but not for other seriesInfo names. For example:
    • <seriesInfo name=“DOI” value=“10.17487/RFC0001”/>
    • <seriesInfo name=“RFC” value=“1”/>

Notes:

• <reference> element:
  • The anchor attribute (which is used to create the citation tag) of the <reference> element should use the following default in bibxml-service entries:
    • anchor=“I-D.draftname” (draftname should not contain “draft-” nor “-NN”. For example, “I-D.ietf-jmap-blob” or “I-D.flanagan-7322bis”)
  • The target attribute:
    • Should use the following URL constructions:
      • I-D: https://datatracker.ietf.org/doc/html/draftname-NN
• <title> element:
  • ASCII equivalents (e.g., double quotes, hyphens) are to be used for punctuation (e.g., to replace smart quotes and em dashes).
• <author> element:
  • non-ASCII in <author> attributes is okay.
  • datatracker provides <organization> elements.
• <date> element:
  • I-Ds have month, day, and year attributes.
• <seriesInfo> element:
  • Although <seriesInfo> can now go into the <front> element, the RPC follows received guidance to keep it out of <front>.
  • I-Ds have one <seriesInfo> element, where draftname includes “draft-”:
    • <seriesInfo name=“Internet-Draft” value=“draftname-NN”/>
• <format> element:
  • Although originally provided by tools.ietf.org bibxml, this element should not be used. See the discussion.
• Numbering:
  • I-Ds have padding of a leading zero for draft version (e.g., “-01”)
