Reto Bachmann-Gmür commented on JENA-31:
----------------------------------------
"The application can analysis the data, make choices of prefixes, set the
prefix map appropriately and call the writer. "
I see that this is a possible work-around, howverrequiring the application to
iterate over the data and determine the prefixed part for every uri seems
highly inefficient.
"Pretty printing RDF/XML requires all the prefixes to be available at the
start. *
Then the pretty-printer has to look at the data and find-out which prefixes are
needed, as uris in predicated position need a prefix this step is necessary
even if all prefixes in the map would be put in the prefix-mapping in the XML
header.
For huge turtle seralization it might be ausefull setting, to limit the number
of triples that are evaluated as possible prefixes, once this number has been
reach subsequent triples never cause a yet unused prefix to be added.

> Currently the serializers want to access the whole set of available
> prefimappings, instead they shold only ask for a prefix suggestion for uris
> actually in the model, that way it is possible to connect services which can
> suggest prefixes for a huge number of uris which is not reasonably feasible
