RFMs Request for modification of the List of

RFMs (Request for modification) of the List of UCD-words

RFMs: • Deletion: The UCD word is to be removed from the list of standard UCDs. Approval of a deletion request should include a statement of what UCD would be used in place of the original UCD. • Amendment: The description of the UCD and/or its syntactic role (primary, secondary, etc. ) and/or its spelling is to be corrected. • A request to better clarify the description of an UCD word that is considered too short or cryptic or ambiguous, and/or to change the syntactic role of the UCD word, is called clarification. • Addition: A new UCD word is to be added. In addition to the general description, there needs to be an indication of the syntactic role, which determines how this word can be combined with other words

RFM: procedure • Sci. Board: 2 -week evaluation • WG: new version of the list open to discussion, PR • Inter. Op: 4 -week RFC • PR to Rec • Shorter loop for “clarifications”

List of RFMs: • Collection, over the past few month, of suggestions to modify/add (mainly add) the present standard list of ucd-words. • RFM for clarification: the semantic definition for all of the UCD words consists of an incomplete sentence. . . to avoid misinterpretations, include richer semantic definitions as part of the document itself
