Joshua, Sounds very useful to me, I use schemagen a fair amount. Looking forward to a patch. The best way to submit it would be to create a new issue on our JIRA site [1], and submit it there as an attachment. -Stephen [1] https://issues.apache.org/jira/browse/JENA On Tue, Jan 29, 2013 at 12

A colleague and I have been using Jena's schemagen to get lots of generated constants from a vocabulary we've developed. We're at the point that we're marking some of the vocabulary deprecated. It would be convenient for our application code that uses the vocabulary if the vocabulary constants th

Thanks for the reply Dave. It seems that jena.apache.org/documentation/ontology/index.html Fig. 5 explains what you are explaining in your email. I still believe thought that javadocs should be more clear about this. Thanks again Regards Papadakos Panagiotis On Tue, Jan 29, 2013 at 3:24 PM, Da

2013-01-29 Thread Michael Brunnbauer
Hello Andy, the problem was a bad block on the disk (I should have checked this first). It was not automatically corrected as TDB tried to read from it and failed (drives only relocate bad blocks on write). I will throw away the TDB on this disk as it is most probably inconsistent and use the ba
