Introduction

XDI ("XRI Data Interchange") is a data model and protocol for sharing, linking, and synchronizing data ("dataweb") over the Internet and other networks using XML documents and Extensible Resource Identifiers (XRIs). It is being developed by the OASIS XDI Technical Committee.

The Higgins XDI4j components is a general-purpose Java library that implement XDI.

Applications that use XDI4j are:

End-User Perspective

XDI4j is a component for use by other components and applications. It is not used by end-users directly.

Developer Perspective

See XDI4j Tutorials for some examples of how to use the XDI4j library.

Architecture

The core functionality of XDI4j is to implement the XDI graph model and to allow basic operations on that model. XDI graphs be stored in memory, in XML files or in a database. Additional functionality includes:

  • (De-)serialization of XDI in the main XDI serialization formats
  • XDI messaging
  • An XDI server including a framework for building custom XDI endpoints
  • Versioning support
  • Addressing support
  • Support for specialized XDI constructs such as dictionary, language, type and metadata statements

The following diagram outlines how the main components of XDI4j play together:

Building

The XDI4j Higgins project is:

  • nursery/org.eclipse.higgins.xdi4j

This project can be checked out from the Eclipse repository at the following SVN URI:

https://dev.eclipse.org/svnroot/technology/org.eclipse.higgins/trunk/nursery/org.eclipse.higgins.xdi4j

Because of Eclipse restrictions some of the XDI4j third party dependencies cannot be checked into the SVN. These dependencies have to be manually downloaded from https://camelot.parityinc.net/~msabadello/xdi4j/lib.zip and installed into the lib/ subdirectory after checking out the sources.

  • The XDI RDF Model is the current OASIS TC proposal for an RDF-based data model and addressing format for XDI. This document includes the proposed XDI RDF schema and a number of examples of XDI documents. (Note that it does not yet include the proposed XDI messaging format, which uses XDI documents as message envelopes for other XDI documents.)
