The Translate Menu is used to translate the current Metalog discourse into N-triples or RDF/XML.
The first two options ("Assertions to N-triples") translate the assertions
of the current discourse to the corresponding N-triple format. This is handy
to export Metalog discourses to other applications, for example, or to study
how information is represented at low level in Metalog. These two options
differ for the fact they allow to either translate "annotations" or not.
In particular:
The third option, Assertions to RDF/XML (no Metalog extensions), translates the assertions of the current Metalog file to the XML syntax for RDF. In the current version, this is limited to files that don't have Metalog extensions ("pure RDF", so to say). This limitation will be likely lifted in a subsequent version: for the moment, just note that this is not essential, as the user can translate any Metalog discourse to N-triples, and then use other public domain tools that take N-triples and output RDF/XML (or, that directly import N-triples). In other words, the goal of interoperability and import/export is already fulfilled by the easier N-triples format.
The remaining three options are:
These are in all similar to the first three options, with the only difference that, this time, just the query part of the Metalog discourse is considered, while all the assertions are ignored.
