Revision as of 17:33, 24 February 2014 by (Talk | contribs) (Release Review Documentation)


This page contains the project plans for the Eclipse Lyo project. The first part of the plan describes the various components of Lyo and the currently planned enhancements to functionality. This plan is subject to changes based on community participation and the importance of proposed functionality to the community - we encourage anyone interested to participate. The planning process will be as open as possible and this plan will be updated as it changes. Please provide feedback on the mailing list.

Lyo Components


  • Documentation
  • Constant strings for OSLC namespaces and providers
  • POJO model for OSLC resources
  • RDF parser and serializer
  • JSON parser and serializer
  • OSLC query parser
  • HTTP client library
  • Basic, Form, OAuth support
  • Client query builder (contributors needed)

Test suite for OSLC

The test suite for OSLC is currently available on the Lyo project. See the Lyo test suite page for details. Currently planned enhancements are

  • Add reporting capabilities
  • Improve Change Management MUST and SHOULD requirement coverage (contributors needed)
  • Improve Requirements and Change Management MUST coverage (contributors needed)
  • Improved query tests (contributors needed)
  • Support for 2-legged OAuth (contributors needed)
  • Add coverage for TRS specification [DONE]
  • Tests driven by resource shape documents [DONE]

Reference implementations for OSLC (RIOs)

Reference implementations are currently available for the Change, Requirements, Architecture Management, Automation, and Tracked Resource Set specifications. See the Lyo reference implementation page for details. Currently planned enhancements are:

  • Refactoring to allow for pluggable RDF and application server technologies (contributors needed)
  • Improve reference implementation web UI [DONE]

Additional Proposed SDKs

Contributors are needed and welcome for all of the following:

  • Perl
  • Python
  • PHP
  • JavaScript

Upcoming Releases

  • Lyo 2.1 is planned for March 2014.
  • Lyo 3.0 is planned for June 2014.

We would like to move to quarterly releases starting with 2.1. Release content will come from the prioritized backlog, stakeholder feedback, and community contributions. Contributions are always welcome! Even small bug fixes help.

Lyo Backlog

Backlog items with rough prioritizations:

  • [HIGH] Build a W3C LDP reference impl and SDK for LDP only
    • Simple JAX-RS + Jena based reference server
    • Reference apps to driver reference server (possibly Node)
    • Build a OSLC V3 ref impl and/or SDK on it
  • [HIGH] W3C LDP test suite
  • [HIGH] OSLC test suite and assessment report consumability
    • Deployable web app
    • Increase MUST/SHOULD coverage
  • [HIGH] - Re-factor test suites to use OSLC4J and drive them via resource shape and service provider resurces
  • [MEDIUM] Automation enablements
    • Hudson/Jenkins
    • Test tools
    • Chef/Puppet
  • [MEDIIUM] - JavaScript client library
    • Consumer navigation of provider (catalog->provider->resources)
    • Helpers for dialogs (frame handlers, etc)
  • [MEDIUM] Orion integration
    • [RDF formats] People like to hand crank some RDF formats, can we do something simple to plug into to provide some simple syntax highlighting and validation
    • [Node.js] Perhaps just a document of how to use Orion to do JS/Node dev with our impl.  FYI
  • [LOW] Perl enhancements, merge libs
  • [LOW] Python examples

Lyo 2.1 (In progress)
