Several pages on the wiki discuss the Lojban Dictionary. Those are collected here:

Dictionary Design


This section is an exploration of the issue started in this discussion about the dictionary backend.

What Are the requirements of a dictionary backend?

  • We want to generate a print dictionary from the data.
  • jbovlaste must be able to use the format.
  • We want to generate flash cards from the data.

What sorts of things *should* a Lojbanic dictionary store, ideally?

  • Are any of these use cases unsuitable for a dictionary? Are there use cases we haven't thought of that are suitable?
  • Can we separate a definition from its grammatical context? Are we treating Lojban gismu too much like a verb or noun in the way we handle them now?


What storage format is going to work for all of these use cases?

  • Each use of the dictionary data needs to view it in a different way. Can we design a format that can be shared between all users of the data?
  • Since the form of a dictionary entry is often unstructured text, What would a dictionary definition look like that supports all of our use cases without duplicating the definitions by changing their form? (e.g., a brief definition for a study card, a full definition for a print dictionary, and an archive discussion for the online dictionary?)

What prior art is there?

  • Dictionaries are not a new problem, how do other people deal with this?
  • Is Lojban fundamentally different because of its formal grammar? Is our thinking on this problem influenced by working with languages that don't have a formal grammar: Is a dictionary a compromise that we have a better solution for?

Design Proposal


gismu, lujvo, and selma'o have different storage requirements. The proposal below assumes they will be storted in a database, and describe the storage schema.

gismu

Field Description
gismu the gismu this row defines
lang the language this row is in
definition the definition of the gismu
x1 gloss for x1
x2 gloss for x2, NULL if there is no x2
x3 gloss for x3, NULL if there is no x3
x4 gloss for x4, NULL if there is no x4
x5 gloss for x5, NULL if there is no x5
xN gloss for xN, NULL if there is no xN


lujvo

Field Description
lujvo the lujvo this row defines
lang the language this row is in
definition the definition of the lujvo
x1 gloss for x1
x2 gloss for x2, NULL if there is no x2
x3 gloss for x3, NULL if there is no x3
x4 gloss for x4, NULL if there is no x4
x5 gloss for x5, NULL if there is no x5
xN gloss for xN, NULL if there is no xN

lujvo-component


Field Description
lujvo the lujvo this row defines
component the component gismu or lujvo that is one part of this lujvo
x1 The position this component's x1 place appears in the lujvo. NULL if it does not appear.
x2 The position this component's x2 place appears in the lujvo. NULL if it does not appear.
x3 The position this component's x3 place appears in the lujvo. NULL if it does not appear.
x4 The position this component's x4 place appears in the lujvo. NULL if it does not appear.
x5 The position this component's x5 place appears in the lujvo. NULL if it does not appear.
xN The position this component's xN place appears in the lujvo. NULL if it does not appear.


There is an entry in this table for each component of the lujvo.
