Dear Lyn,

The XQJ library is based on Charles Foster’s XQJ implementation [1].

Unfortunately, the code has never been made open source, but if you don’t use XQJ (which cannot provide support for more recent XQuery features anyway), just drop the dependency, and you should be fine.

Hope this helps,

Christian

Hi all,

BaseX is an excellent tool, and we are interested in integrating its API into
our open-source project. Our project is licensed under the AGPL-3.0, and we want
to ensure license compatibility with all the libraries we use.

Unfortunately, BaseX depends on the xqj-api library, for which neither a license
nor source code appears to be available. The main concern, therefore, is the
unclear provenance of this dependency.

Could you please provide the license information or the source code for this
library?

Best regards,
Lyn
