You could setup anothe fuseki:Service that uses the same dataset
<#tdbDataset>, define query and GSP read access for that service, then
backup by doing an HTTP get on that name "http://...:3030/myData"; (with
content negotation for format). It should be the shared base data.
<#tdb> rdf:type fuseki:Service ;
fuseki:name "myData" ;
fuseki:serviceQuery "sparql" ;
fuseki:dataset <#tdbDataset> ;
rdfs:label "base data" ;
fuseki:serviceReadGraphStore "get" ;
.

Hi, thanks. I have no idea about how to segregate asserted/inferred triples
in separate graphs!

As I understand it, the backup function just copies triples from the dataset to the file-- it has no way of understanding their provenance. (But I stand to be corrected-- I was pretty far off in my advice to you about trying DROP GRAPH earlier!)
Is it possible for you to change your assembly to segregate your asserted and
inferred triples in separate graphs within the dataset? If so, perhaps you
could use SPARQL Graph Store Protocol [1] to download only those graphs you
want to backup.

Hi All,I'm using Fuseki 3.9.0. I enabled the following reasoner in my assembly
file:
... ja:reasoner [ ja:reasonerURL
<http://jena.hpl.hp.com/2003/OWLMicroFBRuleReasoner>] .
I've noted that doing a backup using Fuseki API
(http://localhost:3030/$/backup/dataset or from web UI) the generated file
includes inferred triples.After restoring such backup inferred relations are
now asserted relations, which is not correct.So here's my questions:
1) is there a way to instruct backup to not include inferred triples?2) if not,
is it possible to disable/enable the reasoner on the fly? In this way I could
disable the reasoner, make the backup, re-enable the reasoner
Thanks a lot
