Method and apparatus for synchronizing metadata, and storage medium storing computer program for executing the method

A method for synchronizing metadata of assets in a system including an MPV file unit and a backward-link information file unit, the method comprising:

• editing metadata of a first asset;
• searching for a backward-link information file of a content which the first asset refers to, in the backward-link information file unit;
• determining whether a second asset detected from the MPV file unit based on the backward-link information file references a same content as the first asset;
• and
• if the second asset references the same content as the first asset, synchronizing metadata of the second asset with the edited metadata of the first asset.

An apparatus for synchronizing metadata, the apparatus comprising:

• an MPV file unit having information for at least one asset;
• a metadata editing unit editing metadata of a first asset;
• a backward-link information file unit having a backward-link information file of at least one content;
• a search unit searching for a backward-link information file of a content which the first asset refers to, in the backward-link information file unit based on information of the first asset provided from the metadata editing unit;
• an asset detector detecting a second asset referencing the same content as the first asset using the searched backward-link information file and the information included in the MPV file unit;
• and
• a synchronization processor synchronizing metadata of the second asset with the edited metadata of the first asset.

A computer-readable medium having embodied thereon a computer program for executing a method for synchronizing metadata,

• the method comprising:
• editing metadata of a first asset;
• detecting a second asset referencing a same content as the first asset using a backward-link information file of a content which the first asset refers to;
• and
• synchronizing metadata of the second asset with the edited metadata of the first asset.
