We introduce two new altmetrics that measure the degree of opennes and collaboration of scholars and institutions. The Open Science Index (OSI) and the Collaborative Open Science Index (COSI).   \begin{itemize}  \item \textbf{OSI: Is the fraction of articles written in the open.} A scholar has OSI of 50\% if half of his articles are private. Similarly, an institution has an OSI of 70\% if 7 out of 10of the  articles authored by affiliated scholars are open. \item \textbf{COSI: Is the fraction of collaborators participating in open articles.} A scholar has a COSI of 67\% if 2 out of 3 co-authors are collaborating on an open article. The COSI is a collaboration-weighted measure of openness.  \end{itemize}
