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; 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 an owner of the metadata to modify or delete the metadata; a server device configured to control write access to the metadata by transferring, using at least one processor, ownership of the metadata to or from a server user that is not an editor; wherein if 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 server device to transfer ownership of the metadata to the server user and each of the one or more editor users without ownership of the metadata is not enabled to instruct the server device to transfer ownership of the metadata; and wherein if the 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 server device to transfer ownership of the metadata from the server user to that one of the one or more editor users.
