The first lines of source code were added to GoogleReaderAPI in 2010. If this older project has had recent activity, then this project likely is consistently delivering value, and attracts sustained effort from the community.
A longer source control history in conjunction with recent activity such as with this project, may indicate that this code base and community have enough value to hold contributors' interest for a long time. It may also indicate a mature and relatively bug-free code base, and can be a sign of an organized, dedicated development team.
Note: The source code for GoogleReaderAPI might actually be older than the source control history can reveal. Many new projects begin by incorporating a large amount of source code from existing, older projects. You might be able to tell whether this is the case by looking for a rapid rise in the amount of code early in the project's history.
GoogleReaderAPI is written mostly in Ruby.
Across all Ruby projects on Open Hub, 18% of all source code lines are comments.
This holds true for GoogleReaderAPI as well. It contains the same ratio of comment lines to code lines as the majority of Ruby projects in Open Hub.
A high number of comments might indicate that the code is well-documented and organized, and could be a sign of a helpful and disciplined development team.
Over the last twelve months, GoogleReaderAPI has not seen any change in activity. This may be a good sign, and an indication that development is continuing at the same pace and not dropping off.
Open Hub makes this determination by comparing the total number of commits made by all developers during the most recent twelve months with the same figure for the prior twelve months. The number of developers and total lines of code are not considered.
The source code for GoogleReaderAPI has not been changed in over a year.
Over 75% of all projects on Open Hub have no recent activity. Open source has a "long tail" of projects whose developers have moved on. But the code is still there for all to benefit from!
For this measurement, Open Hub considers only recent changes to the code. Over the entire history of the project, 5 developers have contributed.
