[Owlim-discussion] Query results in certain situation

Re: [Owlim-discussion] Owlim-SE not responding with high CPU load

Hi, as long as I understand the error and behaviour it causes (I experienced this error few times before so I'm familiar), it can end with two scenarios, but both are considered as blocker/critical bugs: 1. You didn't recieve results which you should recieve (all data indicate the query is

Re: [Owlim-discussion] Loading a Large Triple Store using OWLIM-SE

Hi, if you want to see progress in loading, there is and option to use standard curl command instead of openrdf-workbench. It gives you some information what is already loaded. To load files into owlim(from .trig file), run this command in your linux shell : curl -X POST -H

Re: [Owlim-discussion] [Sesame] Few features request for upcoming 2.7

2. I was not aware that .pie is specific only to OWLIM, therefore my apology. What is then the standard format for rulewriting? What I mean is that in what format are predefined rulesets in Sesame Workbench stores? Main idea was to add custom ruleset in workbench, I agree that editing would not

Re: [Owlim-discussion] [Sesame] Few features request for upcoming 2.7

As it is so, I will create separate pie file and deploy them when they will be ready. Thank you for your explanation. Marek From: Barry Norton barry.nor...@ontotext.com To: Marek Šurek marek_su...@yahoo.co.uk Cc: owlim-discussion@ontotext.com owlim

[Owlim-discussion] Cannot delete repository with changed/removed ruleset

Hi everyone, I experienced one situation which I consider not standard. When I change rules in .pie files or remove the whole .pie file, I cannot DELETE the repository. It ends with following exception : javax.servlet.ServletException: org.openrdf.repository.RepositoryException: Failed to

[Owlim-discussion] Plugin not found in classpath

Hi, I see this error message for quite long time in our logs, but as it was not crucial I ignored it. May I ask what the error message means and why it's there? What are consequences of such error, because error is quite strong log message? We use geo-spatial plugin and lucene plugin, but the

Re: [Owlim-discussion] OWLIM 5.3 - SPARQL and math functions

Hi, there are two options, as long as I know. The first one is to try BIND((?a * ?a) AS ?aSquared) The second one could be to implement own Sesame SPARQL function(if you need complex math function as logarithms etc.). It is quite easy to implement and then insert into lib folder in server :

[Owlim-discussion] Bunch of questions and problems

Hi everyone, during time(summer) I found some problems which I don't fully understand so here they are :). I run OWLIM 5.2(b5316) with Sesame 2.6.9 on both Windows 7 64bit(dev. machine) and Linux(test) server. Some issues are connected to both platforms, some only to Windows. Both enviroments

[Owlim-discussion] Backup in running system

Hi, I want to ask how exactly backup is performed on running system. I read backup part in FAQ and everything seems fine, but I'm confused with word 'seamlessly'. Therefore using programatical approach : 1. Is backup consistency-safe on running system? Does it differ using OWLIM-SE or

Re: [Owlim-discussion] Poor Performance in OWLIM-SE

Hi, I experience the similar issues. The build b5123(OWLIM 5.0) was last build which didn't take advantage of new QueryOptimizer and it gave me expected performance. The new query optimizer(which causes the problems) seems to be fully functioning from build b5183 (at least it was the point

Re: [Owlim-discussion] Owlim-lite Inference

Hi Stefano, its certainly possible and this kind of work relies on TRREE reasoner. There is no default ruleset as long as I know(but in openrdf-workbench the choosen ruleset in selectbox is during creating new repository Empty which is not good for you ). I don't know how you've created your

Re: [Owlim-discussion] Poor performance for Sparql queries with property path optional elements

Hi Ruslan, we have the similar issue (see http://www.mail-archive.com/owlim-discussion@ontotext.com/msg01626.html), which is probably based on the same thing. I don't understand from your response whether the new behaviour is bug or feature. I carefully looked at release notes and nothing so

[Owlim-discussion] Query execution problem between b5123-b5183

Hi, I just recieved the lasted build Owlim 5.1 b5183 and deploy it on our server to test it. I found strange bug related to query execution. The query(INSERT query) took 9 seconds with OWLIM 5.0 b5123(with Sesame 2.6.6), but with build b5183 it runs more that 30 minutes and it is still not at

Re: [Owlim-discussion] Problem with OWLIM, Sesame, Tomcat

Hi, if you don't need to do it through workbench I suggest far easier way to create custom ruleset. My solution is connected to windows... windows 7 64bit 1. Deploytwo official war-files included in owlim distribution .zip file (in folder /sesame_owlim ) by copying them into webapps directory

Re: [Owlim-discussion] CRITICAL FAILURE !!! The database restorer tool has already failed once before to perform image restore.

Hi Monika, I also experienced this exception number of times on OWLIM 4.3. The  problem appears only when I ran openrdf-sesame and client application at the same Tomcat server and due to developing client application I had to restart Tomcat very offen to see changes in my client application.

Re: [Owlim-discussion] Consistency checks with corollaries not implemented

Hi, I think the problem is with your understanding what you should expect from consistency checks. Consistency checks are here to reveal inconsistency in repository/ontology. Therefore they don't produce any consequence (corollary) they just alert in case of inconsistency. If you want to create

Re: [Owlim-discussion] Problem with jdk1.7.0_02

Hi, from my experience there is problem with jdk1.7.x and Sesame. In my case I can't simply run Sesame Console, so I think the issue is connected somehow with sesame. Try to replace your version of sesame lib, with the new one 2.6.3(it is not mentioned on main page but it is in download
