Systems, computer readable storage media, and computer implemented methods for project sharing

摘要

A system enables sharing and locking of metadata defining a NLE project. The system controls write access of metadata by transferring ownership of the metadata between various editor users through an intermediary of a server user. Transfers of ownership of metadata are initiated by editor users. Each editor user is enabled to (a) assume ownership of metadata owned by the server user; and (b) relinquish ownership of metadata he or she owns to the server user. Editor users are only permitted to modify metadata that they own, thereby forming a “check in” and “check out” system for controlling write access to metadata. In effect, metadata is “checked in” when an editor user cedes ownership of the metadata to the server user. Metadata owned by the server user is “checked out” when an editor user assumes ownership of the metadata by taking ownership of the metadata away from the server user.

主权项

1. A computer implemented project sharing system, comprising:
metadata stored in a non-transitory computer readable storage device, the metadata defining a part of a non-linear video editing project; a permissions module configured to assign permissions on the metadata stored in a non-transitory computer readable storage device, the permissions enabling a group of one or more editor users to read the metadata and enabling only one of the one or more editor users with ownership of the metadata permission to modify or delete the metadata; a server device configured to control write access permissions to the metadata by transferring, using at least one processor, ownership of the metadata to or from an intermediary server user that is a fully automated user entity and not an editor user, wherein the transferring comprises:
the server device providing instructions to the permissions module to relinquish or assume the ownership of the metadata to or from the intermediary server user; andthe permissions module updating an ownership indictor and a current status indicator associated with the metadata; wherein the permissions module is configured to transfer ownership of the metadata from or to one of the one or more editor users to or from the intermediary server user, and wherein the intermediary server user is controlled by the server device; wherein when a first editor user of the one or more editor users has ownership of the metadata, the first editor user is enabled to relinquish ownership of the metadata by instructing the permissions module of the server device to transfer ownership of the metadata to the intermediary server user and each of the one or more editor users without ownership of the metadata is not enabled to instruct the permissions module of the server device to transfer ownership of the metadata; and wherein when the intermediary server user has ownership of the metadata, any one of the one or more editor users is enabled to assume ownership of the metadata by instructing the permissions module of the server device to transfer ownership of the metadata from the intermediary server user to that one of the one or more editor users; and wherein the transferring the ownership of the metadata does not require creation of copies or versions of the metadata, or moving a location of the metadata.
