Abstract

An approach is provided for managing projection and injection operations on information spaces with respect to their information content. An information space projection module receives a query to project a first information space from a second information space. In response to the query, the module extracts a subset of information content from the second information space by using a partitioning function. The module also extracts a subset of rules from the second information space by using the partitioning function. The module then creates the first information space using the extracted subset of information content, and the extracted subset of rules while maintains a link between the first and the second information spaces. An information space injection module enables further injection of the first information space back into the second information space.

Claims

1. A method comprising:

receiving a query to inject a first information space into a second information space;

determining whether the first information space and the second information space exist;

determining whether the first information space is on a list of information spaces projected from the second information space, if the first and the second information spaces exist;

applying a filtering function on information content of the first information space and any other information spaces projected from the first information space, if the first information space is on the list of information spaces projected from the second information space; and

adding the filtered information content to the information content of the second information space.

2. A method of claim 1, wherein the filtering function operates on the information content of the first information space and any other information spaces projected from the first information space that has been added, deleted, or modified since projection of the first information space from the second information space.

3. A method of claim 1, wherein the filtering function is based on predefined criteria.

4. A method of claim 1 further comprising:

removing the first information space from the list of information spaces projected from the second information space.

5. A method of claim 1 further comprising:

modifying a history of the second information space based on injection of the first information space.

6. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive a query to inject a first information space into a second information space;

determine whether the first information space and the second information space exist;

determine whether the first information space is on a list of information spaces projected from the second information space, if the first and the second information spaces exist;

apply a filtering function on information content of the first information space and any other information spaces projected from the first information space, if the first information space is on the list of information spaces projected from the second information space; and

add the filtered information content to the information content of the second information space.

7. An apparatus of claim 6, wherein the filtering function operates on the information content of the first information space and any other information spaces projected from the first information space that has been added, deleted, or modified since projection of the first information space from the second information space.

8. An apparatus of claim 6, wherein the filtering function is based on predefined criteria.

9. An apparatus of claim 6 wherein the apparatus is further caused to:

remove the first information space from the list of information spaces projected from the second information space.

10. An apparatus of claim 6 wherein the apparatus is further caused to:

modify a history of the second information space based on injection of the first information space.
