SALT represents an authoring and annotation framework helping the authors to enrich their scientific publications with semantic annotations. The framework is composed by two parts:

• The ontological foundation - is represented by a federation of three ontologies having its roots in the Rhetorical Structure Theory (RST)
• The annotation mechanism - which relies on the textual environment for which SALT was created, i.e. LaTeX

Using the usual LaTeX and a series of new ones (although respecting the usual format), one can easily trasform a normal document in a semantic document. In practice, the annotation process is interleaved with the authoring process. Thus, after compiling the LaTeX document, the resulted PDF document will contain the annotations embedded while writing. For detailed information on the ontology schema and on how to use SALT, please consult the documentation provided on the site.
