LMF (Francopoulo et al., 2006) is a framework for describing lexicons and it has a strong influence on lemon. LMF was primarily intended for XML representation, and it has some constraints and factors we do not have in our RDF-based model
- No named links: Arcs in LMF are not named, in contrast to lemon where they must be named.
- Composition/Association: LMF models relationships between elements as either being compositional or associational, this is not considered important for our RDF framework
- No ontology: LMF does not have an existing ontological framework to build on like OWL.
- Little external linkage: In contrast to lemon, LMF does not refer to other frameworks, or link to other descriptive frameworks (with one exception see below).
As such, although we declare lemon to be highly compliant with LMF, we need now to describe the steps in converting a lemon model to a LMF lexicon.
