OSLC (Open Services for Lifecycle Collaboration): open standard for interoperability of open source ALM tools

Intoduction FLOSS development issues OSLC Interoperability Conclusion
Research interest
Large scale bug-tracking
Lots of duplicate or related bug reports
Not a single place where to monitor bugs
OK, launchpad, maybe. . . too much a silo anyway
No interoperability of tools
Manual work of maintainer / QA (bug triaging, etc.)

Open Services for Lifecycle Collaboration
Quick introduction to OSLC
Open Services for Lifecycle Collaboration :
Lifecycle integration inspired by the Web
The Open Services for Lifecycle Collaboration (OSLC)
community is working to standardize the way that software
lifecycle tools can share data (for example, requirements,
defects, test cases, plans, or code) with one another.

Intoduction FLOSS development issues OSLC Interoperability Conclusion
Tools integration and interoperability
Software development tools integration issues
Lots of different (legacy) systems in respective silos
Integrated suites
Open Source tools or Proprietary Software alike
Software development forges
Agile methodologies vs. monolithic suites
Traceability
Scalability
Very poor interoperability

Intoduction FLOSS development issues OSLC Interoperability Conclusion
Tools integration and interoperability
Integration with silos
Tools are “natively” integrated in isolated suites
Ad-hoc interfaces : no standardization

OSLC (Open Services for Lifecycle Collaboration): open standard for interoperability of open source ALM tools

Intoduction FLOSS development issues OSLC Interoperability Conclusion
Tools integration and interoperability
Continuous integration : FusionForge + JenkinsCI
Jenkins (ex Hudson) as OSLC-CM Consumer
Can create bug reports in case of failed builds/tests on distant
bugtracker
We have developped an Open Source plugin for Jenkins (Java,
Javascript mashup, OSLC-CM plugin published on GiHub)
FusionForge Trackers as OSLC-CM Provider
Handles the bug reports DB, and exhibits an OSLC-CM
compatible REST API
Delegates authentication to consumers on behalf of real forge
users, through OAuth
We have developed an Open Source plugin (PHP + Zend
Framework, published on FusionForge’s SVN)

Intoduction FLOSS development issues OSLC Interoperability Conclusion
Perspectives
More interoperability in FLOSS tools
Push standardization in tools development
Eclipse Mylyn support of OSLC (in the FLOSS parts), based
on Eclipse Lyo roots ? . . . When ?
New opportunities
Open Linked Data for direct “mining” of FLOSS projects
development process metrics
Large scale bug tracking and QA process in the FLOSS
ecosystem
Qui vivra verra. . .
