Dimuthu Upeksha edited comment on JENA-508 at 3/13/15 6:55 PM: --------------------------------------------------------------- Hi Rob, Thank you for the explanation. I went through the documents you have provided and that gave a good idea about how to implement extension functions. Now I'm working on cloning Jena source and trying to implement some custom functions to make sure that I have grasped the details mentioned in those documents. However I'm bit confused about the relevance with project idea (Xpath 3) and extension functions. As far as I have understood project idea is to port functions mentioned in XPath 3 spec to Jena functions in order to give support in SPARQL queries. Am I right? About my availability. Yes usually we don't have summer in our university. However our final exams finish at the end of April. So after April I can spend a significant amount of time (35 -50 hours per week) with the project because academic works are almost over after final exams. Should we move this conversation to mailing list? was (Author: dimuthuupe): Hi Rob, Thank you for the explanation.
