LaunchPad OSCI

[vlad-isayko]

The goal is to create and automate analysis of repos hosted on LaunchPad (https://launchpad.net/). This would be similar to our existing OSCI ranking which analyses repos hosted on GitHub, with a focus on the activity by commercial organizations.

1. Solution that crawls data about push events commits (PEC) that should contain the following required fields:
   • event creation date;
   • commit author (email address, name);
   • SHA.
2. Adapt existing pipeline to process LaunchPad data.

We did a high-level technical analysis on the feasability of making an OSCI for repos hosted on LaunchPad. This is a summary of our findings:

Criteria	Status (Yes/No)	Notes (e.g. about how it is possible, or limitations, etc)
Is this site free to use for open source projects?	yes
Does it look like this site hosts many open source projects?	yes	In total (all projects): “43,314 projects, 1,808,413 bugs, 1,004,760 branches, 17,009 Git repositories, 2,977,004 translations, 685,925 answers, 77,280 blueprints, and counting...”   https://launchpad.net/projects/+all?batch=75Seems to be popular for Ubuntu community mainly.many repos appear to be mirrors of projects which are hosted elsewhere - need more data to provea lot of linux-focused projects
Size of user base	-	c. 4,000,000
Is there a public API we can query?	yes
API type	HTTP
API URL	http://api.launchpad.net/1.0/
Query Limits (if any)	- (to be investigated)
Is there a paid access with more information?	- (to be investigated)
Is it possible to query the project license?	Yes
Is it possible to query commit events/commit counts by a user in a time period?	Yes
Is it possible to query email address or else some organization information for the person making a commit?	Yes	email address (required an authentication)
Is there a public archive we can use instead of the public API?	no
