Presentation of the main components behind gLean - a knowledge-management application which treats problem-domains as a collection of blocks. gLeans USP is in choosing terse components which syntactically do not impede each-other - permitting collections of block to be parsed and interpreted with minimal concerns for complexity. The hope is that gLean will be able to provide YahooPipes style functionality through combining blocks of references; content; annotations; and parsing-logic.

The following areas are covered:

• The talk extols the virtue of the individual components (Gemini protocol's GemText; Emacs-Hyperbole's Kotl; the parser and Lisp, TXR; Jonathan McHugh's Qiuy (a 'Recursive Modelling Language')) as exemplary specialist utilities.

• Examples for how Kotl format and GemText markdown can interoperate (to for instance turning a file into representative Kotl blocks; or export Kotl blocks into GemText)

• The beautiful/unholy ability for TXR to read a 'raw' GemText file containing TXR syntax and for a 'compiled' GemText file to emerge (given this unintended behaviour requires no additional coding and was not designed I consider this particularly special)

• The use of annotations leading blocks to provide logical structures for how a document or a collection of documents should be treated
