The five component Document Model:
| SYNTAX | Interpretation | Realisation | |||
| / | |||||
| / | |||||
Explanations:
Most current document models simply distinguish between two levels: the rendering level and the logical level (the terminology varies). But there is much more to it than that from the linguistic point of view. The components of the document model are entirely analogous to traditional distinctions in grammar, and the distinctions made there are valid at the document level:
| Architecture: | syntax, grammar |
| Meaning interpretation: | semantics, semantic interpretation |
| Content: | logical form |
| Reality | domain model |
| Media interpretation: | phonetic (& graphic) interpretation |
| Layout: | phonology, relational phonological structure |
| Appearance: | phonetic domain(s), absolute phonetic events |
Indeed, the general model can be extended over a hierarchy of units of language of increasing "rank", "size", "granularity":
| Discourse |
| (including dialogue, debate, |
| including discourse prosody) |
| Monologue / Text / Document |
| (including monologue / text / document components, |
| including prosodic text components) |
| Sentence |
| (including simple/complex, tensed/tenseless, |
| including prosodic sentence components) |
| Word |
| (including simple, derived, compound, inflected, |
| including prosodic word components) |
| Morpheme |
| (including prosodic morphemes) |
| Phoneme |
| (including tonemes and other autosegments) |
