[basex-talk] Origami presentation XML Amsterdam
Hi, Anyone on the list coming to Amsterdam the 6th of November? We may have some beers together. I will (finally) be presenting on the Origami templating library. I'm still working on it over on Github (in the unstable branch). After a pause in development it was almost completely rewritten. I intend to cut a new release just before the conference. Here's the anouncement I made for the conference website. XQuery 3.1 is still a candidate for recommendation by the W3C. Nevertheless there are already various implementations ready for use today. The introduction of maps and arrays, and the availability of functional weaponry such as fold and apply may change the way you write XQuery applications. You can still wield the trusty weapons of XPath and the FLWOR expression while, at the same time, adopting a more functional style of programming. Origami is an ongoing exploration of templating in XQuery and it makes heavy use of this functional style. It started with a quest for a more XSLT-like transformation capability and recently took a nice turn with the adoption of a flavor of micro-XML, with a heavy reliance on maps and arrays. Origami's unfolding design tries to honour principles of simplicity and composability. With Origami I aim to decomplect, or disentangle, several aspects common to templating problems and offer them in a powerful library using a couple of simple abstractions. With some practical code examples I will demonstrate how to use Origami to implement different templating styles. --Marc
Re: [basex-talk] crypto module with binary files
Hi Michel, As the function only accepts strings as input, you can either explicitly cast your binary item to string – via xs:string($binary)… or contact the author of the module (Claudius Teodorescu) and issue a feature request.

Re: [basex-talk] Java access to JSON-to-XML transformation
Hi Hans-Jürgen, Sure, that's possible. This is one of the entry points [1]. As you already indicated, it's not based on any well-defined API, so it is subject to change. Have you already done some testing what's the current bottleneck in terms of performance (e.g. by using the Java flag -Xhrunprof)? Maybe you can already save time by creating instances of the QueryProcessor class (see e.g. [2]).

[basex-talk] crypto module with binary files
Greetings all, I would like to perform cryptographic operations with arbitrary binary files but am unable to figure how to convert the output of file:read-binary() to something that could be processed by crypto:hmac() for example. Can You give me a hint please? TIA Best regards Michel
