Hi Quentin,

the following statement is important; quoting your email as forwarded by Christian:

> As such, transformation between RDF and XML using XSLTs is not optimal and XSLTs need to be tailored  to different flavor of RDF/XML (which is costly). 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.

Indeed many manually-crafted XSLTs suffer from this, …

… and such libraries are the solution.  With https://github.com/EIS-Bonn/krextor I have another one (technically it's a collection of XSLT templates and functions that provides an abstraction layer), which you may be interested in looking at.

> However, we have seen issues with the performance of transformation as well as increase in complexity. In other words, it is  difficult to maintain as requirements for transformation change.

However, Krextor is clearly not optimised for performance, but rather for expressiveness and flexibility.
