thank you Claus, there is obviously much more in the Jena-extensions (SmartDataAnalytics / jena-sparql-api).
if you want to contribute your work to the Jena project you will have to follow up with Andy directly. But I am not sure this is necessary at the moment since you already provide the code in the public domain conveniently as an extension / add-on to the Jena project, which I think is great as is for now. Over time we might want to learn from your work and add aspects to the overall core Jena project I would think. It would be great if we could schedule a zoom session in order to give us an overview of the "SmartDataAnalytics / jena-sparql-api" extensions could you prepare such a presentation in the coming days? best, Marco On Wed, Mar 18, 2020 at 3:34 PM Claus Stadler < cstad...@informatik.uni-leipzig.de> wrote: > Hi, > > > The SparqlStmt API built against jena 3.14.0 is now available on Maven > Central [1] in case one want to give it a try (example in [2]) and give > feedback and whether one thinks it would be a useful contribution to Jena > directly - and what changes would be necessary if so. > > > <dependency> > <groupId>org.aksw.jena-sparql-api</groupId> > <artifactId>jena-sparql-api-stmt</artifactId> > <version>3.14.0-1</version> > > </dependency> > > > [1] > https://search.maven.org/artifact/org.aksw.jena-sparql-api/jena-sparql-api-stmt/3.14.0-1/jar > > [2] > https://github.com/SmartDataAnalytics/jena-sparql-api/blob/def0d3bdf0f4396fbf1ef0715f9697e9bb255029/jena-sparql-api-stmt/src/test/java/org/aksw/jena_sparql_api/stmt/TestSparqlStmtUtils.java#L54 > > > Cheers, > > Claus > > > > On 18.03.20 16:04, Andy Seaborne wrote: > > Note that parsing the string as a query aborts early as soon as it finds > an update keyword so the cost of parsing isn't very large. > > > > Andy > > > > On 18/03/2020 11:58, Marco Neumann wrote: > >> is there some utility function here in the code base now already to do > >> this, or do I still need to roll my own here? > >> > >> On Tue, Jul 30, 2013 at 4:25 PM Andy Seaborne <a...@apache.org> wrote: > >> > >>> On 30/07/13 10:13, Arthur Vaïsse-Lesteven wrote: > >>>> Hi, > >>>> > >>>> I would like to know if Jena offers a way to detect the type of an > >>> unknow SPARQL request ?Starting from the query string. > >>>> > >>>> At the moment the only way I succed to code it without "basic parsing" > >>> of the query ( sort of thing I prefer avoid, manually parsing string > with > >>> short function often create errors ) > >>>> looks like this : > >>>> > >>>> [...] > >>>> String queryString = "a query string, may be a select or an > >>> update"; > >>>> > >>>> try{ > >>>> Query select = QueryFactory.create(queryString); > >>>> Service.process_select_query(select);//do some work with > >>> the select > >>>> } > >>>> catch(QueryException e){ > >>>> UpdateRequest update = > UpdateFactory.create(queryString); > >>>> Service.process_update_query(update);//do some work with > >>> the update > >>>> } > >>>> catch(ProcessException e){ > >>>> //handle this exception > >>>> } > >>>> > >>>> [...] > >>>> > >>>> So is it possible ?
