Many of these are very well-knownSome maybe less so:

RDF, BEEP, SOAP, IMPP, XKMS

Basic formats

ASN.1 MIME XML RDF >> RDF extensions work >>

RDF

General metadata/knowledge representation Uses XML syntax, but also...

Simple directed labelled graph data model Uniform use of URIs as concept identifiers Open-ended extensibility Integrates diverse information sources and allows information sharing

between overlapping applications Leverages existing ontology and reasoner work RDB implementations

Basic semantics simple assertions, with a well founded notion of entailment supports formal reasoning

RDF extensions work

RDF schema DAML+OIL/OWL RuleML W3C vision for a “web of trust”

Basic protocols

HTTP - web access SMTP - mail transfer BEEP SOAP Instant messaging

SIP/SIMPLE Jabber APEX

BEEP

An application protocol framework client-server and peer-to-peer interactions

Provides framing, modular security, capability negotiation, request/response correlation, pipelining, multiplexing

Solves many common application protocol issues

SOAP

Envelope structure for message exchangeEncoding (marshalling) framework for

non-XML dataBinding to HTTP for RPC and response

message exchange patterns

Instant messaging

Proprietary offerings ICQ, AOL, MSN, Yahoo

IRC SIP/SIMPLE Jabber APEX Presence is an important capability

Asynchronous notification by publish/subscribe mechanism
