Abstract

A system and method for using soft links to managed content is described, wherein data is stored within a content repository in the form of nodes arranged in a hierarchical structure. Soft links are created and associated with content nodes by having a reference pointer to a node that is resolved by the content repository. A soft link may be implemented as a skeleton node containing no actual storage data except to point to the actual content node. Nested soft links are also supported wherein a soft link may reference another soft link which can reference a node or yet another soft link. Checks for cyclical infinite loops can be performed. Soft links can be presented as pointers to regular content nodes to the users. This can enable users to arrange and customize data while saving on storage costs and preventing duplication of data.

Claims

1. A computer implemented method for using soft links with managed content, said method comprising:

storing data within a content repository, said content repository containing said data in a plurality of content nodes arranged in a hierarchy structure;

creating at least one soft link and associating said soft link with one of said plurality of content nodes of the content repository, said soft link containing a reference pointer to said one of said plurality of content nodes or to a second soft link;

accessing said soft link by one or more users; and

resolving said soft link by said repository by traversing down said reference pointer until said one of said plurality of content nodes is reached.

2. The method according to claim 1 wherein said creating a soft link and associating said soft link with the one of said plurality of content nodes further includes:

creating a new hierarchy structure by said one or more users, said new hierarchy structure including a plurality of soft links, said plurality of soft links referencing said plurality of content nodes within the content repository.

3. The method according to claim 1 wherein said soft link is implemented as a skeleton node within said plurality of content nodes, said skeleton node containing no storage data except to point to the content node associated with said soft link.

4. The method according to claim 1 wherein said soft link is presented to said one or more users as pointer to a regular content node from said plurality of content nodes arranged in the hierarchy structure, such that said one or more users are able to access data contained by said regular content node.

5. The method according to claim 1, further comprising:

constructing a query by said one or more users, said query determining which soft links point to a specified soft link.

6. The method according to claim 1 wherein creating at least one soft link and associating said soft link with one of said plurality of content nodes of the content repository further includes:

performing a cyclical infinite loop check to prevent a first soft link from referencing a second soft link if said second soft link already references said first soft link directly or via any intermediate soft links.

7. The method according to claim 1 wherein deleting a soft link will not delete the content node associated with said soft link.

8. A system for using soft links with managed content, said system comprising:

a content repository for storing data in a plurality of content nodes, said content nodes arranged in a hierarchy structure;

at least one soft link created within said content repository and associated with one of said plurality of content nodes of the content repository, said soft link containing a reference pointer to said one of said plurality of content nodes or to a second soft link;

wherein said soft link is automatically resolved by said repository upon a user attempting to access said soft link, by traversing down said reference pointer until said one of said plurality of content nodes is reached.

9. The system according to claim 8, further comprising:

a new hierarchy structure created by said user, said new hierarchy structure including a plurality of soft links, said plurality of soft links referencing said plurality of content nodes within the content repository.

10. The system according to claim 8 wherein said soft link is implemented as a skeleton node within said plurality of content nodes, said skeleton node containing no storage data except to point to the content node associated with said soft link.

11. The system according to claim 8 wherein said soft link is presented to said user as pointer to a regular content node from said plurality of content nodes arranged in the hierarchy structure, such that said user is able to access data contained by said regular content node.

12. The system according to claim 8, further comprising:

a query constructed by said user, said query determining which soft links point to a specified soft link.

13. The system according to claim 8 wherein creating at least one soft link and associating said soft link with one of said plurality of content nodes of the content repository further includes:

performing a cyclical infinite loop check to prevent a first soft link from referencing a second soft link if said second soft link already references said first soft link directly or via any intermediate soft links.

14. The system according to claim 8 wherein deleting a soft link will not delete the content node associated with said soft link.

15. A computer readable medium having instructions stored thereon, which when executed by one or more processors, cause a system to:

store data within a content repository, said content repository containing said data in a plurality of content nodes arranged in a hierarchy structure;

create at least one soft link and associate said soft link with one of said plurality of content nodes of the content repository, said soft link containing a reference pointer to said one of said plurality of content nodes or to a second soft link;

access said soft link by one or more users; and

resolve said soft link by said repository by traversing down said reference pointer until said one of said plurality of content nodes is reached.

16. The computer readable medium according to claim 15 wherein said instructions for creating a soft link and associating said soft link with the one of said plurality of content nodes further include instructions that cause the system to:

create a new hierarchy structure by said one or more users, said new hierarchy structure including a plurality of soft links, said plurality of soft links referencing said plurality of content nodes within the content repository.

17. The computer readable medium according to claim 15 wherein said soft link is implemented as a skeleton node within said plurality of content nodes, said skeleton node containing no storage data except to point to the content node associated with said soft link.

18. The computer readable medium according to claim 15 wherein said soft link is presented to said one or more users as pointer to a regular content node from said plurality of content nodes arranged in the hierarchy structure, such that said one or more users are able to access data contained by said regular content node.

19. The computer readable medium according to claim 15 wherein a query is constructed by said one or more users, said query determining which soft links point to a specified soft link.

20. The computer readable medium according to claim 15 wherein instructions for creating at least one soft link and associating said soft link with one of said plurality of content nodes of the content repository further include instructions to cause the system to:

perform a cyclical infinite loop check to prevent a first soft link from referencing a second soft link if said second soft link already references said first soft link directly or via any intermediate soft links.
