Re: GSoC : SPARQL in Rules : mid-term checkpoint

Just a quick difference of opinion. I think that @Test(expected=Rule.SparqlRuleParserException.class) public void sparqlInRule_NN() { parseRuleString("...") ; } is a bad pattern, and that tests where an exception is expected are better served with try catch blocks catching the expected exceptio

Re: reply: TDB OPTIMIZER question:a puzzled of RULE language about " VAR and TERM "

Quick question: Would it make sense to have an immutable flag that would tell the optimizer (or other processes) that a dataset/model/graph is not likely to change? More of a hint rather than a rule. On Thu, Jun 12, 2014 at 2:15 PM, Rob Vesse wrote: > You may be interested in the follow

Testing Proposal

I would like to see Jena adopt a set of contract tests. I recently wrote an article for Dr. Dobb's [1] concerning contract testing. In it I use the experimental/new_tests as an example. The basic concept is we provide a set of contract tests for expected extension points like the Graph SPI. Imp

Re: How to safely apply transformations to custom algebra operators?

Are there a class of operators that should not be done bottom up? I am thinking along the lines of there are classes of operators that are not transitive. Perhaps there is a name for this property. If we can identify it and name it, we could flag it in the operator implementation so that the tra

Re: Sketching for jena3

I would still like to see Node as a serializable object, or some standard mechanism to get a serialized version of the node. Any thoughts along this path would be appreciated. I had thought about something along the lines of a type byte and raw data as a serialized form. But that would mean that

jena-commons

Howdy, I have started a new experimental package jena-commons. This is intended to be a set of classes that implement or extend interfaces that are external to the Jena package. For example, the implementation I contributed is an implementation of the Apache Commons Configuration interface that
