[basex-talk] Prolog and XQuery

[Ben Engbers]

Hi,

My ultimate goal is to investigate the advantages of using Prolog and 
XQuery together when querying XML files. In doing so, I want to take 
advantage of BaseX's XQuery engine.
Since there is no Prolog client, I initially started writing a Prolog 
client. But in SWI-prolog, I did not manage to connect using the 
webconnection tools. So I first started to write a C++ client and then 
start writing a bridge in Prolog that uses that client. The starting 
point for the C++ client was the RBaseX client I published earlier. I 
converted all functionalities from that client to C++. A preliminary 
version of the C++ client can be found at 
https://github.com/BenEngbers/BasexCpp. As soon as I manage to create a 
real shared object using CMake I will publish a final version.

Regarding the server protocol for BaseX, however, I still have a 
question. According to that protocol, the ADD command accepts 4 
arguments ({09 {name} {path} {input} ). However, neither in R nor in C++ 
have I succeeded in using the {name} argument.  My question is whether 
this is a bug in the protocol?

I don't know if there is a need for a C++ client that implements the 
full server protocol but in any case I enjoyed working on this project.

Have fun,
