This document summarizes a presentation about RESTful work items and opening up collaborative application lifecycle management (ALM). It discusses the problem of integrating many different ALM tools, proposes using open standards like OSLC to define REST APIs, and demos integrating Tasktop and ClearQuest using OSLC. The presentation outlines the current state of the OSLC Change Management specification, previews upcoming version 2.0, and concludes by discussing next steps for OSLC adoption.

ALM and Change Management at IBM
Many tools to integrate
Solutions require it
Products are:
New
Legacy
Acquired
ISVs and Partners

7. IBM Rational Software Conference 2009
SLI04
ALM Solution Pain Points
Integrations built for
point-to-point products
Products can’t be
updated independently
Differing (incompatible)
models

8. IBM Rational Software Conference 2009
SLI04
Tasktop case for open services
Tremendous interest a Mylyn connector for
ClearQuest
Each one-off WS API comes with a burden
Legacy ALM tools are not going away soon
Need for a common, REST based API
URL-addressable resources, loose coupling
Ecipse/Mylyn support for generic functionality

…and then there became OSLC
Open Services for Lifecycle Collaboration
Introduced at RSDC 2008
Open community contribution
Scenario driven...a minimalist approach
Divided into focus areas
Change Management  Focus of this talk
Quality Management, Estimation & Measurement, Requirements Management, …
Solving integration in the open

OSLC Architectural Drivers
Working with RESTful architectural principles
(the Web seems to scale ok)
Leverage existing
standards:
XML, HTTP, Dublin Core
Keep the barrier to
entry for existing
products low

11. IBM Rational Software Conference 2009
SLI04
Current state of OSLC Change Management
Finalized 1.0 specifications
Scenarios:
Find and fix a defect
Agile planning of change requests
Technical capabilities:
Discovery of services
Metadata is not needed (resource creation and selection is delegated)
Minimal resource definition
RESTful resource manipulation: create, modify

OSLC CM 1.0 – Service Discovery
- Don’t require URI building and fixed segments
 URLs for services
are discovered
 There may exist
multiple levels of
context

13. IBM Rational Software Conference 2009
SLI04 13
OSLC CM 1.0 – Delegation
 Resource Selection
A way to pick (search for and select)
 Resource Creation
Use POSTed data to seed a Web
UI, allowing delegated, user-
attended creation of change
requests from a loosely coupled
client
 Creation and Selection rely on a
simple JavaScript API to return
URLs to the caller

OSLC - Interoperability in Heterogeneous Landscape
Tasktop
Company behind Eclipse Mylyn has joined OSLC
Tasktop Pro is the commercial version of Mylyn + ALM integrations
Both open source and closed source tools leveraging OSLC
Demos
Task-focused programming
Task creation via OSLC (open source)
ClearQuest integration via OSLC (closed source)

Tasktop experiences participating in OSLC
OSLC solves a business problem for us
Process is open and participative
IP policies enable both our OSS
implementation and commercial extension
Lightweight & RESTful are a good way to go
Approach will affect the ALM landscape
We’re not done yet, need repository shape...
