"One solution that we have used is to transform the RDF input
(in any supported syntax) to be converted into a XML canonical
form prior to applying XSLTs. "
<clange> help
processing RDF data in XML / xslt workflows
christian: also covered by one XML prague scenario
<quentin> canonical format new to be optimized for performance
christoph: similar solution is here
[15]https://lists.w3.org/Archives/Public/public-rax/2016Jul/000
7.html
... has RDF abstraction layer, this is independent of RDF
output serialization
... related: what RDF abstract serialization to use
[15] https://lists.w3.org/Archives/Public/public-rax/2016Jul/0007.html
collection of state of the art canonical representations of RDF
in XML
quentin: you should always optimize canonical format that you
are processsing
<clange> there is, e.g., RXR (Regular XML RDF), there is TriX,
and there are more
quentin: XSLT is generally not enough, one needs libraries on
top of XSLT
christian: "processing RDF data in XML / xslt workflows" -
important topic, has several solutions, we need to collect info
what works good, what not etc.
<clange> sources for the canonical formats mentioned above: RXR
([16]https://www.dajobe.org/papers/xmleurope2004/), TriX
([17]https://www.w3.org/2004/03/trix/,
[18]https://en.wikipedia.org/wiki/TriX_(syntax) )
[16] https://www.dajobe.org/papers/xmleurope2004/),
[17] https://www.w3.org/2004/03/trix/,
[18] https://en.wikipedia.org/wiki/TriX_(syntax)
<clange> AFAIK there is also a newer approach based on the
SPARQL XML results format

<scribe> ACTION: felix to add people to rax-cg github [recorded
in [20]http://www.w3.org/2016/07/08-rax-minutes.html#action01]
[20] http://www.w3.org/2016/07/08-rax-minutes.html#action01]
quentin: happy to do the description. won't be able to go
through all material that christoph provided
christoph: happy to help
<scribe> ACTION: quention to start section on RDF data in XML /
xslt workflows topic. christoph to add material [recorded in
[21]http://www.w3.org/2016/07/08-rax-minutes.html#action02]

TimeaT: previous problems, solutions were sent directly per
mail. there was also a template, not sure how to send input
Christian: use the template, send to the list
<clange> BTW my colleagues will write up their two use cases
(AutomationML Industry 4.0 and GATE NLP) by the next telco.
mapping XML of dictionary data to RDF
timea: dictionary company stores data in XML format, for
further publishing. They wanted to bring XML into RDF, to be
able to enrich dictionaries
... they can be multi- or monolingual, because language is
complex
... need a way to convert XML to RDF
... for working with dictionaries you have to use lemon /
ontolex, which may be extended
... solved currently with XSLT
... writing the XSLT proved to be very long and tedious
... not sure if we can achieve a general XSLT
... next step is how to connect words between dictionaries
... we reached very good point with XSLT, just wondering if
there is a better way
felix: so no integration of RDF in XML needed?
timea: would have been desired, but dropped because XML mapping
took a long time
... roundtripping is difficult
... not sure if it is needed
christoph: for making it easier to create XML / RDF
translation, there are solutions
... I have developed something, felix has one
... so this should be a part: write a classification of
existing libraries
... e.g. libraries that are based on XSLT. You start with that
and it becomes hard to maintain, then people add an abstraction
layer
... adding link to my implementation here
<quentin> for RDF -> XML, an approach could be to use SPARQL
and XML templates
<quentin> ... essentially creating registere queries
<clange> [22]https://github.com/EIS-Bonn/krextor is a library
of XSLT templates and functions for XML to RDF
[22] https://github.com/EIS-Bonn/krextor
timea: we used "unified views", etl tool that read the XML and
writes all data into virtuoso
... the actual mapping if endepend of unified views
<clange> @Timea see
[23]http://ceur-ws.org/Vol-449/ShortPaper2.pdf for an old,
high-level overview
[23] http://ceur-ws.org/Vol-449/ShortPaper2.pdf
[24]http://fsasaki.github.io/stuff/feisgiltt2016/
[24] http://fsasaki.github.io/stuff/feisgiltt2016/
felix: currently purely XSLT based solution, without an
abstraction layer
timea: classification of existing libraries, describe their
drawbacks etc.
christoph: would contribute to such a section
<quentin> depending on the complexity of the transformation,
you can use XPATH and templates to populate the RDF
<scribe> ACTION: timea to start section on existing tools &
their classification, benefits and drawbacks - others to
contribute [recorded in
[25]http://www.w3.org/2016/07/08-rax-minutes.html#action03]
[25] http://www.w3.org/2016/07/08-rax-minutes.html#action03]
quentin: you can also just use XPath and java @@@ and then are
able to keep mappings
... you can do similar things from RDF > XML perspective, using
SPARQL templates
timea: that sounds familiar how the XSLT is built; has a lot of
templates
... we transformed the XML in a simple RDF, and then converted
RDF into the model needed
... ontolex / lemon + extension
christioph: I have pointers to further systems, have seen a
related paper
... will add a link here
... on roundtripping, let's not forget the XSParql
specification
... it combines XQuery and SPARQL
<clange> SPARQL templates for RDF to XML have actually been
implemented as a proper language:
[26]https://hal.inria.fr/hal-01150623/document. XSPARQL
([27]http://xsparql.deri.org/) does a similar job but it's IMHO
more suited for queries over XML or RDF or both at the same
time, rather than transforming whole RDF graphs or whole XML
documents.
[26] https://hal.inria.fr/hal-01150623/document.
[27] http://xsparql.deri.org/)
christioph: it is better for query than complete
transformation, but very interesting approaches
<quentin> there is an overlap between the two use-case in terms
of transformation from 1 format to another
felix: asking john on mark logic support for RDF and how it
fits into the picture
other sections & topics
nothing at the moment
next call in two weeks from now
same time
john: we are working on tech. to store RDF in XML
... also to make it easier to work with XML described by RDF
graph
... interested to see in problems that people have and finding
solutions
adjourned
