Robin's essay contains a proposal that the BPFK should be guided by principles on what the purpose of the Lojban language is.

Ideally, we should have a document that is precise and unambiguous, and that everyone finds, if not perfect, then at least acceptable.

On this page, we outline a process for compiling such a document.

1. Summarizing earlier statements of purpose, and arguments thereof

• Loglan 1: A Logical Language
• The Complete Lojban Language
• What Is Lojban?
• Mailing list discussions
  • Elephant metaphor (Summary: Lojban is different to everyone, and thus has no single, unified goal)

2. Writing up descriptions of contemporary goals

To the extent that they have not already been clearly described.

3. Determining the ranking of the goals

4. Any other work
