This article discusses issues arisen during implementation of XEP-0136 specification, which describes the protocol for server-side instant messaging history, and XEP-59, which basically provides the way to page through results set and limit results number.

Basically, it’s the copy of letter sent to XMPP discussion mailing list, I’ve put it here to make sure more people have access to it and can provide their feedback / comments.

For most of the issues listed some solutions are proposed.

This article is about mod_archive_odbc: ejabberd implementation of server-side instant messaging history support, also known as XEP-136.

Update: development of this module has stopped, all further development is done in mod_archive2 project.

This article introduces libwsw - C++ library for Jabber clients which provides XEP-136 support, AKA server-side message archiving, and wswutil - the tool for import / export operations on user history for XEP-136 compliant servers.
