Protocols provide developers with another possible avenue for building their own applications and extensions. For example, if you are building a client application to connect with multiple repositories from multiple vendors, including Alfresco Content Services, then CMIS is a consideration. If you are building a client to connect via the SharePoint Protocol, then use the Alfresco Office Services (AOS). Protocols provide a resource for developers, in addition to the numerous other extension points and APIs built into Alfresco.
When any of these protocols are used to access or upload content to the repository, access control is always enforced based on configured permissions, regardless of what protocol that is used.
The following table list some of the main protocols supported by Alfresco Content Services and links to more detailed documentation.
