Good day, I was just wondering what the reasoning was behind letting the getAll() method clear the contents of the QueryResults instance? In other words after...
I've been running some tests to see how well the RDB storage scales up to workloads that I would like to be able to handle. I realize that using RDB involves...
Hi there, I guess that this behaviour surprises you :-) The main problem is the operation shouldn't really be in the QueryResults interface at all - or at ...
Luke, I can answer some of your points: Dave Reynolds, who wrote the RDB support, is away this week. This mismatch between the fine-grained Jena API and the...
Dear All, This is just a test to see if I can now post to jena-dev again. You don't need to reply or anything - if I see it myself, I shall assume it all...
(this message originally got eaten by Yahoo's sudden decision that I was persona non grata; Andy's reply has alluded to the stuff I describe below). ... For...
... Good question. There's nothing in the proposed revised architecture that would "stamp" statements as inferred as opposed to explicit. (Indeed, since one...
Just out of interest, Inkling does SquishQL to SQL rewriting, and checks to see whether the database supported can accept SQL queries before dumbing down to...
... I'm wrong here. That is what it *should* do. The constructor QueryResultsMem(QueryResultsMem) is not public and it takes an unnecessary copy despite what...
(I've combined responses to Chris's and Andy's posts because my answer is related) Thanks for all the suggestions. I will also look into the Inkling ...
Luke, You'll have to wait for Dave about the bulk loading. Again, inside an explicit transation might be faster. How often do you load the database? ...
Hi all, does anyone know why I have the following exception every time my program using Jena terminates? I'm using an Oracle/MMGeneric DB to open the default...
I haven't seen this but looking at the code I can see it could happen. Would be easy to fix but in fact will be fixed anyway as a side-effect of proposal I...
... Not at present. The current Model.add(model) code does a single listStatements() to the database which is about as effecient as the current API can manage....
... (and later said...) ... I'm not certain, but I think that your idea for preloading the literal/resources table would make a huge difference. I turned on...
We have created a subclass of DAMLClass, and Jena doesn't seem to recognize it as a DAMLClass. Is our assumption correct that we should be able to create a...
... Actually it only does that for the objects of the statements, the subject and predicate data is retrieved inline. The reason for not retrieving the objects...
I thought I'd pass this on, though you may see it elsewhere. Brian =================================================================== WWW2003 CALL FOR PAPERS ...
Have you considered making ModelMem (and other Jena-classes) serializable? Really easy :) I'm working on a J2EE architecture using Jena as the RDF-storage ...
Interesting thought! Did you do the same for Resources, Literals etc? If so how did you cope with the Model reference in Resources? If you tag ResourceImpl etc...
I'm made a few modifications to the jena RDB module in the sourceforge CVS. As usual, being in CVS means that it passes all current regression tests but ...
Luke, I've taken a look at the bulk loading issue and, as you may have seen from my ealier message, added a model.loadAll() command to do a bulk load. I tested...
Dave, Thanks very much for your prompt help, again. I've tried things out and this helps considerably, though there is something strange going on. (Aside:...
I download the new version of Jena toolkit (1.5.0) today and try to run the example of RDQL. But some error messages are displayed on the screen as below: ...
I have a similar problem. I downloaded Jena 1.5.0 and I ran the Sample5 code okay. But I can't run the tutorials. They will not compile. When I try to...
