Andy Seaborne commented on JENA-508:
------------------------------------
The full list of the XPath Functions and operators in {{StandardFunctions}} and
we have a nearly complete set.
Summary notes for tracking purposes: I think we have only these missing
(sequence operations do not make sense in SPARQL):
{noformat}
fn:format-number
fn:format-dateTime
fn:format-date
fn:format-time
fn:normalize-space
fn:normalize-unicode
{noformat}
It would be nice to have {{op:}} mapping (but there are a lot of them) and
adapters to SPARQL operations that have keywords:
{noformat}
fn:replace
fn:matches
{noformat}
{{fn:normalize-space}} : leading and trailing whitespace removed, and sequences
of internal whitespace reduced to a single space character. (regex \v and \h)
{{fn:normalize-unicode}} : the Java {{Normalizer.normalize}} applies the rules.
{{fn:format-number} : Java {{NumberFormat}} picture strings.
{{fn:format-dateTime}}/{{fn:format-time}}/{{fn:format-date}} : Java
{{SimpleDateFormat}}
> Add support for XPath 3 Functions

> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ
> Reporter: Rob Vesse
>
> XPath 3 is now a Candidate Recommendation -
> http://www.w3.org/TR/xpath-functions-30/
> It contains many new functions and operators (particularly in the
> mathematical space) which we should consider adding into future versions of
> ARQ.
