This week I implemented a new module: mod_archive_muc, a simple version of mod_archive, which is the implementation of XEP-0136.
In mod_archive_muc, we simply archive every message regardless of the collection. And retrieve them later with any combination of three filtering attributes - 'with', 'start' and 'end'. This is much simpler than mod_archive.
The Next Step:
* Go on finalizing the code.
* Do testings.
* Prepare for the final evaluation.
