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.
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.
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.
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, 8 developers have contributed.
