As a libosinfo maintainer I strongly discourage you from writing a custom API directly against the XML. While the format is stable from the POV that vendors/users can create new XML docs for new/customized OS variants they have, we do not consider it something for applications to be using directly. The libosinfo library API includes alot of logic beyond simply being an convenient way to process the XML. In particular dealing with the inheritance of data across OS, searching for data across a variety of data sources, relying on GIO for URI resolving, live update of the database, and more. We're also not really interested in maintaining manually written bindings for any languages. Rather than putting effort into such bindings for Java, time is better spent on finishing the GOBject introspection mapping layer for Java. There was a proof of concept, which was never finished / updated to the final introspection spec, which can be used as a basis for ongoing development. https://live.gnome.org/JGIR This work will be applicable way beyond just libosinfo, to a wide variety of useful APIs. Of possible interest to VDSM in the future will be things like the new libvirt-designer & libvirt-builder APIs which are going to provide a bridge between libvirt + libosinfo to simply life for application developers constructing XML for provisioning guests.
