Re: [Owlim-discussion] Adding rules to an existing repository.
Thanks Ivan! I've read the user guide section 5 and I have a question that isn't answered there: Is it possible to have multiple ruleset files for a repo? When I modified the swiftowlim.ttl file to assert multiple owlim:ruleset, I got an error. Does this mean I have to combine my custom_rules.pie with the builtin_owl2-rl-conf.pie into one ruleset file?

Re: [Owlim-discussion] Adding rules to an existing repository.
Hi Danny, in short - you can use only a single ruleset file - so you need to find a way to combine both into a single .pie - the easiest way is to start with one of those we provide with the distribution and alter it accordingly.

[Owlim-discussion] Delta updates of Lucene FTS index
Hi, I am working with a bigowlim store with Lucene FTS index enabled. The search itself works fine, but I did not yet find a way to populate changes of the rdf data to the lucene index. Recomputation of the whole index is not an option due to the amount of RDF data and the amount of changes to the RDF data. Is there a way to update the lucene index so these changes are reflected in the next FTS-request?

Re: [Owlim-discussion] Delta updates of Lucene FTS index
Hi Tobias, We don't currently support incremental lucene index updates. The reason why we don't is that lucene indexing in OWLIM doesn't only process simple literals and URIs but works on whole molecules. This means that adding a single statement can modify several previously indexed molecules. Those dependencies are possible to track but we weren't willing to pay the hight computational and storage price in order to facilitate incremental updates to the index. Can you tell us more about your usage scenario? How big is the repository in terms of # of statements, # of different entities, how often there would be updates, how big do you expect them to be and also (most importantly) how much time does it take to run the full lucene re-indexing on the repository. Another question that I need to ask is if it would work for you if we gave you an option to incrementally update the index but only for the newly added entities and leave the possibly updated old indexed molecules untouched? In such a scenario one will be able to do small incremental updates to the index for the new objects coming in (even automatically) and then re-index old objects once every while (on an interval a lot larger than those of the updates).

[Owlim-discussion] Input data to storage size ratio question
Hi all, I was wondering about the expected behaviour of a BigOwlim repository (using the OWL/Max ruleset) with regard to its disk space consumption. For example I noticed that the loading of 2198 RDF/XML files (1177.03125 MB) resulted in the creation of 1871.6606 MB on the server end (in the .aduna/openrdf-sesame-repositories/MYREPOSITORYNAME/owlimTest-storage directory) which represents a storage ratio of ~ 1.59 between the loaded data and the input RDF documents. Is this ratio going to remain more or less constant regardless of the incoming data? What affects the size of the files on the server end? The reason that I am asking is that I am currently loading 71000 files (~ 193 GB), a process that was started las Monday and I was wondering if I will have enough HDD space :S.

[Owlim-discussion] Release update notification question
Hi all, I was wondering if it would be possible to set up a way of notifying registered users when a new release of BigOwlim become available. Regards, Jose ___ OWLIM-discussion mailing list OWLIM-discussion@ontotext.com http://ontotext.com/mailman/listinfo/owlim-discussion
