XEP Coverage

Overview

DJabberd targets to be a Perl Toolkit for XMPP, from which you can build a solution, including communication server. As such majority of XEPs are implemented as external plugins. If some XEP is supported natively that's ususally done either as a show-case (limited functionality, should be extended by plugins) or as being necessary for normal functionality (eg. compatibility layer unlikely to be implemented as plugin).

List of supported XEPs

XEP-0170	N/A	Recommended Order of Feature Negotiation	Implemented in Core - Connection will add tls first, then anything else in specified by plugins order. SASL/Auth are ignored if tls is mandatory.
XEP-0178	N/A	SASL External - best practices for TLS Certificate authentication	Implemented in Core (since v0.90 in DJabberd::SASL::Connection::External, DJabberd::SASL::AuthenSASL, DJabberd::Stanza::SASL)

XEP-0368	N/A	SRV records for XMPP over TLS	Implemented in the Core (since v0.90) as external SSL facilitated (offloaded) TLS. SSL Offload engine needs to tackle SNI/ALPN, DJabberd will demux the stream based on stream headers/attributes.
XEP-0384	urn:xmpp:omemo:1:devices urn:xmpp:omemo:1:bundles	OMEMO Encryption (Server support)	While server does not interact directly with OMEMO, the protocol relies on certain features on the server, namely extended PEP features (as described in Section 7.1). DJabberd::Plugin::PEP::Spool supports those prerequisites.
XEP-0398	urn:xmpp:pep-vcard-conversion:0	Avatar to VCard conversion	Implemented in the DJabberd-VCard (since v0.60) as another storage engine. Which converts posted VCard into PEP and retrieves VCard from PEP. But only PHOTO tag, anything else is discarded.
