Re: fuseki status [get status after ./fuseki-server or java -jar]
very good Vincent, and yes Jena/Fuseki is indeed a great foundation for any LOD project. the good news is that you already use shiro by virtue of running fuseki. I highly recommend you take a look at the fuseki UI. you can simply edit the shiro.ini in the fuseki_run folder. just comment out /$/** = localhost and add /$/** = authcBasic,user[admin] and you are good to go. take a look at the features. you can load data, check the status and create new named graphs etc. I am not sure who works on the UI at the moment but I'd like to see more of it in the future. just looking at your sparql endpoint. is 346,746,619 your total number of triples at bnf? what's the public endpoint url? http://carmen1.bnf.fr:9880/sparql ?

Re: fuseki status [get status after ./fuseki-server or java -jar]
Thanks Marco! My use case is very simple : I'm building a sample dataset with RDF data from http://data.bnf.fr + a kind of "php-fuseki sandbox" where the user will find examples of queries and php functions that show to reuse the data. There also will be a small visualization library (developed with javascript vis.js) that allows to explore the dataset (by drawing networks via construct queries). I don't use Shiro, only a very quick install of fuseki (not even set environment variables : the objective is to produce both a tutorial and php code, easy to understand and to install). If you want to have a look, I've just uploaded some files here : https://sourceforge.net/projects/ffl-misc/files . It's still a draft of course. A next step would be to translate the explanations into English and ask the community if s.o. is interested to review the code : our research project also aims at producing educational resources, and we think that fuseki is ideal to learn LOD technologies. These files are adapted from my other project, which is more complex : it's a kind of collaborative platform where users produce both archival description and personal annotations. The platform is built on Code Igniter and has authentication system ; here I could consider using Shiro & admin tools.

Re: fuseki status [get status after ./fuseki-server or java -jar]
Thanks Marco. It seems to be mapped /$/server and AFAICS has not been mapped to /$/status., only mentioned in shiro.ini. Easy enough to add a second servlet-mapping if that's what people want (the difference is that by default, /$/status is acess to anon and /$/server is accessible only to the admin UI). Thoughts?

Re: fuseki status [get status after ./fuseki-server or java -jar]
Hi Andy,
Thanks a lot for the explanation! I'm going to have a look at the script.
Anyway, since I'm not able to know how the user started the server, it
seems that I have to combine ps and netstat (if netstat provides useful
information about the server, it may be interesting to inform the user).
Have a nice day
Vincent

Hi Vincent,
The script "./fuseki" runs Fuseki as an OS service, and it is a
wrapper around "java -jar fuseki-server.jar". It is the script that
records the process id and makes OS tools concerned with OS services
know about Fuseki. If you run the server directly then there isn't a
record of the running service.
To see if Fuseki is running via "java -jar" or "fuseki-server" then
you'll either have to look for the process or see if the port is
in-use with something like netstat.
