Reto Bachmann-Gm=C3=BCr commented on JENA-31:
----------------------------------------

"The application can analysis the data, make choices of prefixes, set the p=
refix 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 seem=
s highly inefficient.

"Pretty printing RDF/XML requires all the prefixes to be available at the s=
tart. *
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 nece=
ssary 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 num=
ber of triples that are evaluated as possible prefixes, once this number ha=
s been reach subsequent triples never cause a yet unused prefix to be added=
.

> Currently the serializers want to access the whole set of available prefi=
mappings, instead they shold only ask for a prefix suggestion for uris actu=
ally in the model, that way it is possible to connect services which can su=
ggest prefixes for a huge number of uris which is not reasonably feasible n=
ow.
