Abstract

A computer-implemented method for selecting a portion of a content repository for replication including receiving an input describing one or more desired relationship patterns for replication, generating a query for the desired relationship patterns, identifying content items of a content repository matching the desired relationship patterns, and selecting the identified content items of the content repository. The input is received at a graphical user interface (GUI). The GUI operates on a computer. The relationship patterns are associated with an ontology describing relationships between content items in a content repository. The content repository includes a plurality of content items.

Claims

1. A computer-implemented method for selecting a portion of a content repository for replication, comprising:

receiving, at a graphical user interface (GUI) operating on a computer, a selection of a content item in a content repository and an input describing one or more desired relationship patterns for replication, the relationship patterns associated with an ontology describing logical relationships between the selected content item and other content items in the content repository, the content repository including a plurality of content items, wherein the content items comprise digital documents, wherein the ontology is stored in one or more tags associated with one or more content items in the content repository;

generating a query for the desired relationship patterns;

identifying the selected content item and related content items of the content repository to replicate to a target storage device based on a storage capacity of the target storage device, wherein the target storage device is separate from the content repository, wherein the related content items comprise a logical relationship with the selected content item based on the desired relationship patterns; and

selecting the identified content items of the content repository.

2. The computer-implemented method of claim 1, further comprising extracting the identified content items and storing the identified content items on the storage device.

3. The computer-implemented method of claim 2, wherein the storage device is a portable storage device.

4. The computer-implemented method of claim 1, wherein the GUI comprises a display indicating selected relationship patterns.

5. The computer-implemented method of claim 1, further comprising receiving, at the GUI, an input indicating a maximum allowable size for the selected content items.

6. The computer-implemented method of claim 5, wherein the GUI comprises an indicator to indicate the size of the selected content items relative to the maximum allowable size.

7. The computer-implemented method of claim 1, further comprising receiving, at the GUI, an input deselecting a selected relationship pattern.

8. The computer-implemented method of claim 1, wherein receiving the input describing one or more desired relationship patterns includes receiving, at the GUI, an input describing a desired type of relationship for selected content items.

9. The computer-implemented method of claim 1, wherein receiving the input describing one or more desired relationship patterns includes receiving, at the GUI, an input describing a type of content item to retrieve.

10. The computer-implemented method of claim 1, wherein receiving the input describing one or more desired relationship patterns includes receiving a number of allowed transitive steps for selected content items.

11. The computer-implemented method of claim 1, wherein the query comprises at least one query selected from the group consisting of:

a triple pattern;

a disjunction;

a conjunction; and

an optional pattern.

12. The computer-implemented method of claim 1, wherein the ontology is stored in a triplestore.

13. A computer program product comprising a computer useable storage medium to store a computer readable program, wherein the computer readable program, when executed on a computer, causes the computer to perform operations for replicating a portion of a content repository, the operations comprising:

receiving, at a graphical user interface (GUI) operating on a computer, a selection of a content item in a content repository and an input describing one or more desired relationship patterns for replication, the relationship patterns associated with an ontology describing logical relationships between the selected content item and other content items in the content repository, the content repository including a plurality of content items, wherein the content items comprise digital documents, wherein the ontology is stored in one or more tags associated with one or more content items in the content repository;

generating a query for the desired relationship patterns;

identifying the selected content item and related content items of the content repository to replicate to a target storage device based on a storage capacity of the target storage device, wherein the target storage device is separate from the content repository, wherein the related content items comprise a logical relationship with the selected content item based on the desired relationship patterns;

selecting the identified content items of the content repository;

extracting the identified content items; and

storing the identified content items on the storage device.

14. The computer program product of claim 13, wherein the content repository describes a product.

15. The computer program product of claim 13, wherein the content repository is associated with a social network.

16. The computer program product of claim 15, wherein the social network comprises an at least one collaboration mechanism from the group consisting of:

a social structure of individuals and organizations;

email;

instant messaging;

a wiki;

a blog;

media sharing;

collaborative tagging and subject indexing; and

an avatar-based virtual world.

17. The computer program product of claim 13, wherein the storage device is a portable storage device.

18. An apparatus for replicating a portion of a content repository comprising:

a graphical user interface (GUI) to receive a selection of a content item in a content repository and an input describing one or more desired relationship patterns for replication, the relationship patterns associated with an ontology describing logical relationships between the selected content item and other content items in the content repository, wherein the content items comprise digital documents, wherein the ontology is stored in one or more tags associated with one or more content items in the content repository;

a semantic engine to identify the selected content item and related content items of the content repository to replicate to a target storage device based on a storage capacity of the target storage device, wherein the target storage device is separate from the content repository, wherein the related content items comprise a logical relationship with the selected content item based on the desired relationship patterns; and

a replication engine to extract the identified content items and store the identified content items on a storage device.

19. The apparatus of claim 18, further comprising a query generator to generate a query for the desired relationship patterns.
