Re: Contributing to the code
Hi Andy,
it took me some time to understand how the code is organized but I think
that I have completed the JENA-967 task. I have still some doubts but I
need to show you the code to explain my problem. I wanted to make a pull
request on github but I was denied access. Do I need to do something lese
before having access to the repository? My github account is under
cicerone54@hotmail.com.

Yes - the jena-text and jena-spatial are similar but as a fixed-term
GSoC project, jena-spatial had to copy the code of jena-text as a
starting point.
It would be good if they shared more - they both use Lucene.
Osma has been working on jena-text recently and may have some thoughts
or ideas of what could be done in and around this area.

Andy,
as the Xpath3 task is finished I am ready in starting a new task.
According to the list of things you wrote to me the last time, this one is
the one that got my attention:
*2/ The Spatial query and text query modules share a common framework but
the text one has had work done on it and the spatial one hasn't. It would
be good to find the common framework and redo the spatial query module to
share the general mechanisms with the text query.*
Could you explain a bit better what you mean? Is there a task corresponding
to this?
Otherwise if you think that there are other tasks more important at the
moment. I am open to suggestions.

Alessandro

Alessandro,
I've added you to the Jena contributors group on JIRA.
This should enable you to modify JIRA more easily.
("should" because how JIRA works in this area is a bit of a mystery to
me! The project does not have it's own JIRA instance so we don't have
complete flexibility over the setup.)

Andy,
I started working on task JENA-508 namely adding these fn functions:
fn:normalize-space
fn:normalize-unicode
fn:format-number
fn:round-half-to-even
fn:adjust-dateTime-to-timezone
fn:adjust-date-to-timezone
fn:adjust-time-to-timezone
fn:format-dateTime
fn:format-date
fn:format-time
but I cannot change the status of the task. Is there something I need to do
in order to change the status ?

thank you for getting back to me! I will give a look to the list of things
you wrote to me and try to get some insight on them. 1/ and 5/ seems the

Hi there,
The tasks could use some cleaning and categorising. IMO many of the
open ended tasks over, say 2year, could be resolved "won't fix" and a
note to reopen only there is new input.
Anyway, some suggestions:
1/ JENA-647 : This is adding template queries to Fuseki.
The idea is that server has a service where instead of a query, the
requests has a template name and values for variables. A template lists
some variables that must be defined as part of its definition in an
assembler.
Such a service means a published dataset can have just a fixed set of
template queries to access it.
http://localhost/3030/ds/template?id=nameoftemplat&var_A=<http://example>&var_B=123
First step is to write a design.
2/ The Spatial query and text query modules share a common framework but
the text one has had work done on it and the spatial one hasn't. It
would be good to find the common framework and redo the spatial query
module to share the general mechanisms with the text query.
3/ Bruno was looking at JENA-632 (JSON from SPARQL) : Bruno - is there
anything here to collaborate on?
4/ There was a discussion users@ about better formatting of JSON-LD.
This is not an open ended pretty printed project (which is hard and no
one is ever happy with the outcome!); it's to let a JSON-LD @context be
passed through the writer code in the RIOT context (same word -
completely different thing - it's a map of parameters) and then be
passed to the 3rd part JSON-LD writer Jena uses.
5/ JENA-508 - there are some missing XQuery/Xpath functions list at the
end of this JIRA. I think with those, jena would have all the relevant
ones (that is, the ones on scalars and not specific to XML).

In XSD, any number to string should be happening locale-independent, ie
Locale.ROOT so the issue has never come up before. You need to get the
Locale in force.

What should work is to fork http://github.com/apache/jena in github,
work on the clone ("git:" URL) cloned to the local machine, then do a
github UI "pull request". Is that what you tried? What access denied
did you get?

Hi,
I forgot another thing: is there a way to get the locale that should be
used for string conversion inside the
jena-arq/.../sparql/expr/nodevalue/XSDFuncOp class? I need this to convert
