Hi
I have recently complied a list of commercial tools that provide OSLC support. The survey describes in detail which OSLC capabilities are supported to which tools.
You can download the survey from An Analysis of the OASIS OSLC Integration Standard - A Survey | Zenodo.
I also plan to keep the list of tools up to date as a Google Sheets. So, please feel free to update me on tools that I have not yet found.
A report that summarises this survey, as well as give general reflections over OSLC implemenation can be found as
