Method and apparatus for content repository with versioning and data modeling
View Patent ↗The present invention is related to method and apparatus for versioning. Versioning information is stored as metadata associated with data entities. A hierarchical relationship between the entities allows the definition of an editorial sequence and separate revisions within that sequence as well as relationships between sequences in a self-contained format.
1. A content repository computer system comprising a storage device for a plurality of persistent data entities including metadata each entity having a predetermined level of scope such that within a set of related data entities, the scope of an entity at a higher level encompasses the scope of related entities at a lower level of scope, wherein at least one entity includes metadata that identifies a sequential relationship between one or more entities within the scope of said one entity, each of said entities including metadata defining a position within said sequential relationship.
2. The system according to claim 1 , wherein a further entity includes, in addition to metadata identifying a sequential relationship between one or more entities within the scope of said further entity, metadata identifying as a source of said sequential relationship, one of said entities within the scope of said at least one entity.
3. The system according to claim 1 , wherein said storage device is connected to a network.
4. The system according to claim 1 , including a plurality of said storage devices.
5. A content repository computer system comprising a storage device for a plurality of persistent data entities including metadata each entity having a predetermined level of scope such that within a set of related data entities, the scope of an entity at a higher level encompasses the scope of related entities at a lower level of scope, wherein within the scope of an entity at a higher level there exists at least one entity at an intermediate level whose metadata identifies a sequential relationship between one or more entities of a lower level and within the scope of said one entity, each of said entities at said lower level including metadata defining a position within said sequential relationship.
6. The system according to claim 5 , wherein a further entity at said intermediate level includes, in addition to metadata identifying a sequential relationship between one or more entities of a lower level and within the scope of said further entity, metadata identifying as a source of said sequential relationship, one of said entities at a lower level within the scope of said one entity at said intermediate level.
7. The system according to claim 5 , wherein said storage device is connected to a network.
8. The system according to claim 5 , including a plurality of said storage devices.
