We just had a discussion w/ @kittisopikulm about Java APIs and bindings for HDF5. Besides idiomaticity, ease of deployment in the target environment is perhaps the most important usability consideration. For the HDFql guest in a Java host, this suggests that an HDFql Maven package might deliver a usability boost for Java developers and users. @contact, have you considered this deployment option? Any showstoppers? I believe that expertise is abundant in the community to help such an effort if other commitments or priorities prevent you personally from pursuing this.
The same goes for the JNI bindings; we’ll start a separate discussion on that.
