Overview of Abdera Modules
Abdera is composed of a number of individual modules:
Core: Provides the core interfaces used throughout Abdera:
Feed Object Model
- A set of Java interfaces and abstract classes modeled after the various document and element types defined by the Atom specifications.
Parser and Factory interfaces - Interfaces that provide the mechanisms for creating and consuming Atom documents.
ExtensionFactory - The primary means by which extensions to the Atom format are integrated into Abdera. Extension Factories are used by both the Parser and Factory.
Writer - The means by which Feed Object Model objects are serialized into XML or other formats (
Custom Writers
JSON Serialization
ParseFilter - Provides a means of filtering the stream of parse events
Converter - Base interfaces and utilities for converting objects into Feed Object Model objects
XPath - Base interface for navigating the Feed Object Model using XPath
Dependencies: Contains all of the other jars and code Abdera depends on
Parser: Provide an implementation of the Feed Object Model based on the Apache Axiom project
Protocol: Provides the base interfaces and utility classes used for the RFC 5023 (Atompub) implementation
Server
: Provides framework code used to build Atompub servers
Client: Provides an Atompub client implementation that is based on the Apache Commons HTTP Client.
Spring
: Extends the Server module by adding support for the Spring framework
Security: Provides support for XML Digital Signatures and XML Encryption
Extensions
: Provides support for a number of standard and non-standard extensions to the Atom format
Atom Threading Extensions
Atom License Extension
Atompub Feature Discovery

Are the Axiom dependencies accurate?

I had great troubles with that. I was using the latest release of abdera (1.1.2) and of axiom (1.2.12). It worked most of the time, but I got some strange crashes other times. This document could obviously not be trusted, so after digging through the svn repository I found what version of axiom I needed (1.2.10). Hope someone can make this clear in the future.
