3. 3 © 2012 IBM Corporation Eclipse Lyo  Eclipse Lyo 1.0 officially released 10/10  Address Challenges in Adoption  Library to build Providers and Consumers  Test Suites to validate implementations  Samples  Eclipse Lyo was just a thought 18 months ago  http://eclipse.org/lyo

4. 4 © 2012 IBM Corporation Eclipse Lyo  Eclipse project created with the goal of providing tools to enable adoption of OSLC specifications.  Content includes –Code libraries (Java, Perl, others under development)  Give developers tools to ease OSLC implementations –Reference implementations of specifications  Provide a starting point for new integrations –Test suites and test reporting. Covers OSLC Core, CM, QM, RM and Asset today.  Accelerate and assess development –Samples, tutorials and documentation  Working samples of OSLC integrations with Bugzilla, Excel, Jazz tools and more.

5. 5 © 2012 IBM Corporation Code Libraries - Java  OSLC4J - Java library for OSLC provider and consumer implementations  Based on OSLC-related Java annotations and JAX-RS for REST services  Modular structure avoids forcing dependencies on specific technologies.  Jena and Apache Wink provide RDF, JSON and JAX-RS capabilities out the box  Serialization/Deserialization of annotated POJOs to/from RDF/XML, JSON and OSLC Compact  JAX-RS annotation of Java methods representing OSLC GET/PUT/POST/DELETE  Takes care of building OSLC artifacts like Service Provider and Resource Shape docs  Samples implemented in OSLC4J  Change Management, Quality Management, Automation Specifications –Good “stub” provider examples –Currently missing query and delegated UIs (Automation delegated UIs almost ready)  Bugzilla Adapter –Full set of delegated Uis –Supports OSLC queries –Has been used as a base for some production usages

7. 7 © 2012 IBM Corporation Where is OSLC4J and Lyo at today?  Recently had 1.0 release + graduation from Eclipse Incubator status  OSLC4J + Test suites  Packaged with Eclipse Foundation approved versions of dependencies  Also packaged without dependencies for consumers which have their own approved versions of the dependencies  Currently being used in shipping commercial and non-commercial OSLC integrations  Documentation and “How To” guides are lacking  Basic Javadoc is there  Need a cookbook for putting together an implementation  OSLC Workshop (see the docs) repository provides some of this  Anyone can help with these – start a page on the Wiki or update an existing page

8. 8 © 2012 IBM Corporation Agenda  OSLC4J and Lyo update  Client libraries  Test suite update  Future plans

9. 9 © 2012 IBM Corporation Client libraries  OSLC4J and its samples are tilted towards provider implementations  CM, QM, Bugzilla samples are all providers  JAX-RS service examples are for provider or adapter implementations  OSLC4J and JAX-RS concepts are a good fit for consumers too  Java definitions of OSLC resources  JAX-RS/Wink client APIs to access resources from a consumer  New work in Lyo to add libraries focused on consumer scenarios  Java and non-Java

10. 10 © 2012 IBM Corporation Code Libraries – Java Client  Java OSLC and Jazz client library  Uses OSLC4J as its basis  Generic OSLC client API  Resource definitions (ChangeRequest, TestCase, AutomationPlan, etc)  GET/PUT/POST/DELETE APIs  Serialize/De-Serialize Java representations of OSLC resources to/from RDF/XML and JSON  Handles query and paging  Jazz-specific add-on APIs and classes  Rootservices handling  Jazz form login  Samples:  RTC  RQM  Sample Automation consumer  Under active development – looking for contributions

11. 11 © 2012 IBM Corporation Code Libraries – Other Java Libraries  OSLC Query Library Assists with parsing and manipulating OSLC queries  Handles oslc.where, oslc.select, oslc.orderBy, oslc.searchTerms and oslc.prefix  Handles wildcards and property nesting.  Uses Antlr package to parse/lex OSLC query syntax  Utility class to invoke parsers and return structured objects representing query clauses  Example implementation in the OSLC4J Bugzilla adapter  OAuth Library  Set of packages + web app intended to ease adding OAuth 1.0/1.0a provider support to an application Core package : provides basic configuration and validation services Consumerstore package : provides persistence of consumer and token information Webapp package : WAR for request/access token handling + basic UI for key management and approval Uses Googlecode OAuth library Adoption/Sample usage OSLC4J Bugzilla sample

12. 12 © 2012 IBM Corporation Code Libraries – non-Java  Perl client libraries  Lyo::OSLC  Client library geared towards Rational OSLC CM implementations (RTC and CQ)  Use case is for GET/Query/Read scenarios  Net::OSLC::CM  Client library geared towards Bugzilla and Simple Defects (synchwith.us)  Perl representations of OSLC Catalog, ServiceProvider, ChangeRequest  Use case is also around GET/Query/Read scenarios  See http://open-services.net/resources/presentations/eclipse-lyo-perl-modules-mini-cast-3-pack for a recent webcast. OSLC4Net – C# SDK for provider and consumer implementations Contribution is being readied - not yet available Based on OSLC4J – approach uses C# annotations Uses dotNetRDF (RDF marshalling/unmarshalling) and ASP.NET MVC 4 (REST services) Includes Change Management implementation

13. 13 © 2012 IBM Corporation Agenda  OSLC4J and Lyo update  Client libraries  Test suite update  Future plans

14. 14 © 2012 IBM Corporation OSLC Test Suite Update  OSLC Test Suite and Reports  Measure implementation compliance against Core and domain specifications  Improve implementation quality by finding bugs  Initial focus is on MUST items, followed by SHOULD and MAY  Reports provide both summary and detailed results

15. 15 © 2012 IBM Corporation What’s new in the test suite  Coverage of Asset and Quality Management specs added in July  Initial coverage for Requirements Management added in September  Some re-factoring of test suites to improve  Re-use of common code  Isolate OSLC Domain tests (CM/QM/AM/RM) from OSLC Core tests  Improvements for running reports  Suites are being used for regression and development testing by several products and organizations  Areas for enhancements  Drive tests from resource shapes and service provider documents  OAuth tests  Use OSLC4J for higher level tests

16. 16 © 2012 IBM Corporation Agenda  OSLC4J and Lyo update  Client libraries  Test suite update  Future plans

17. 17 © 2012 IBM Corporation Future contents  4Q2012 or 1Q2013  Package client libraries and dependencies for easier consumption  Package query library with OSLC4J and standalone  Improve documentation Themes for future releases: SDKs for technologies other than Java (Python, JavaScript/Node.js,.NET, etc) Test suite improvements (additional domain coverage, improved depth of test cases, improved reporting) API stabilization Improved documentation Usability
