CMIS Spec Uncovered

1,898

Published on

CMIS became an OASIS standard earlier this year. It has the potential to impact content repositories in the same way that SQL impacted relational databases all those years ago. In this session you'll learn about the goals of CMIS, its domain model and services, without any of the hype from a member of the CMIS technical committee. If you attend this session, you'll save yourself from the 250 pages of the specification. This is knowledge that will apply not only to Alfresco, but also all other major content repositories.
