Abstract

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.

Claims

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; and

the 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.

2. The system of claim 1, wherein the metadata is stored in a file stored in a directory, and wherein the permissions on the metadata comprise directory-level permissions and file-level permissions.

3. The system of claim 2, wherein the directory-level permissions include a sticky bit.

4. The system of claim 1, wherein the metadata is stored in one or more database entries of a database.

5. The system of claim 1, further comprising instructions stored on at least one non-transitory computer readable device, wherein execution of the instructions by at least one processor causes the graphical user interface to be presented on at least one presentation device, the graphical user interface enabling instructions to transfer ownership of the metadata to be sent to the server device.

6. The system of claim 5, wherein the graphical user interface comprises the current status indicator for the metadata, the current status indicator indicating, to one of the one or more editor users, that the metadata is currently available to be checked out, currently checked out by that one of the one or more editor users, or currently checked out by a different one of the one or more editor users.

7. The system of claim 1, wherein the server device runs on a Linux based, a Unix based, or a Unix-like operating system.

8. A computer implemented method, comprising:

setting, using at least one processor, permissions on 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;

controlling write access to the metadata by transferring, using at least one processor and upon receiving an instruction through at least one input device, 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;

providing instructions to a permissions module to relinquish or assume the ownership of the metadata to or from the intermediary server user; and

the 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 a 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 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.

9. The computer implemented method of claim 8, wherein the first user has ownership of the metadata, and wherein the method further comprises:

receiving, through at least one input device, an instruction from the first user editor to relinquish ownership of the metadata; and

based on the received instruction, transferring, using the at least one processor, ownership of the metadata from the first user to the intermediary server user.

10. The computer implemented method of claim 8, wherein the intermediary server user has ownership of the metadata, and wherein the method further comprises:

receiving, through at least one input device, an instruction from one of the one or more user editors to assume ownership of the metadata; and

based on the received instruction, transferring, using the at least one processor, ownership of the metadata from the intermediary server user to the one of the one or more user editors.

11. The computer implemented method of claim 8, wherein the metadata is stored in a file stored in a directory, and wherein the permissions on the metadata comprise directory-level permissions and file-level permissions.

12. The computer implemented method of claim 11, wherein the directory-level permissions include a sticky bit.

13. The computer implemented method of claim 8, wherein the metadata is stored in one or more database entries of a database.

14. The computer implemented method of claim 8, further comprising instructions stored on at least one non-transitory computer readable device, wherein execution of the instructions by at least one processor causes the graphical user interface to be presented on at least one presentation device.

15. The computer implemented method of claim 14, wherein the graphical user interface comprises the current status indicator for the metadata, the current status indicator indicating, to one of the one or more editor users, that the metadata is currently available to be checked out, currently checked out by that one of the one or more editor users, or currently checked out by a different one of the one or more editor users.

16. An interactive electronic display of information for a first editor user of a non-linear video editing program, the first editor being assigned to a non-linear video editing (NLE) project comprising a plurality of metadata, the display comprising:

a plurality of metadata indicators representing the plurality of metadata defining the non-linear video editing project, wherein each metadata of the plurality of metadata is owned either by an editor user representing an editor assigned to the NLE project or by an intermediary server user that is a fully automated user entity and does not represent an editor user assigned to the NLE project; and

for each metadata of the plurality of metadata, an associated status indicator selected from the group consisting of;

a first status indicator indicating ownership of the metadata by the intermediary server user;

a second status indicator indicating ownership of the metadata by the first editor user and identifies the first editor user as owner of the metadata; and

a third status indicator indicating ownership of the metadata by another editor user that is not the first editor user and identifies another editor user as owner of the metadata;

wherein a permissions module updates the first status indicator, the second status indicator, or the third status indicator associated with the metadata; and

wherein the first editor user is only permitted write access to the metadata of the plurality of metadata that is owned by the first editor; 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.
