storing a harvested content object corresponding to the content object, wherein the harvested content object comprises the metadata associated with the learning content of the content object stored in the first repository.

2. The method of claim 1, further comprising:

generating information from the metadata associated with the learning content of the content object; and

if the harvested content object is located in a search for content objects performed at the second repository, providing the generated information along with the harvested content object in the search results so that when the search results are displayed, the generated information for the harvested content object is displayed in a substantially similar manner as when corresponding information is displayed for local content objects stored at the second repository.

3. The method of claim 1, wherein the retrieving of the metadata is performed using a modified version of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) protocol, the modified version comprising an Extensible Markup Language (XML) schema that extends metadata items provided in the OAI-PMH protocol to include the metadata associated with the learning content.

4. The method of claim 1, wherein the learning content comprises a Learning Management System (LMS) type of the content object.

5. The method of claim 4, further comprising:

recognizing the LMS type of the harvested content object as being the LMS type of the content object;

determining an action that can be performed for the harvested content object based on the LMS type; and

performing the action for the harvested content object.

6. The method of claim 5, wherein the LMS type comprises an assessment, and wherein the action comprises integrating the harvested content object into a LMS gradebook.

7. The method of claim 5, wherein the action is the same as that which would be performed for a local content object that is also of the LMS type, stored at the second repository.

8. The method of claim 1, wherein the learning content comprises usage information for the content object.

9. The method of claim 1, wherein the learning content comprises relationship information for the content object with respect to one or more other content objects.

10. The method of claim 9, wherein the relationship information for the content object comprises structure information that indicates that the content object contains, or the content object is contained within, the one or more other content objects.

11. The method of claim 9, wherein the relationship information for the content object comprises sequence information that indicates that the content object is recommended to be used before or after the one or more other content objects.

12. The method of claim 9, wherein the relationship information for the content object comprises information indicating that the content object and the one or more other content objects are members of a same collection of content objects.

13. The method of claim 1, wherein the learning content comprises at least one of:

information indicating an instructor using the content object;

information about a student who is able to access the content object;

information indicating a course using the content object; and

information indicating an institution using the content object.

14. A computer-readable medium storing instructions for obtaining metadata for content stored in a first repository, wherein when the instructions are executed by a processor of a server hosting a second repository, the processor is configured to:

identify a content object stored in the first repository, the content object comprising learning content usable in an electronic educational system to provide electronic learning;

identify metadata for the content object stored in the first repository, the metadata associated with the learning content of the content object;

retrieve the metadata associated with the learning content from the first repository; and

store a harvested content object corresponding to the content object, wherein the harvested content object comprises the metadata associated with the learning content of the content object stored in the first repository.

15. A server comprising:

a memory that is configured to store instructions for hosting a second repository that obtains metadata for content stored in a first repository; and

a processor that is coupled to the memory, the processor being configured to execute the instructions, identify a content object stored in the first repository, the content object comprising learning content usable in an electronic educational system to provide electronic learning;

identify metadata for the content object stored in the first repository, the metadata being associated with the learning content of the content object;

retrieve the metadata associated with the learning content from the first repository; and

store a harvested content object corresponding to the content object, wherein the harvested content object comprises the metadata associated with the learning content of the content object stored in the first repository.

16. The server of claim 15, wherein the processor is further configured to:

generate information from the metadata associated with the learning content of the content object; and

if the harvested content object is located in a search for content objects performed at the second repository, to provide the generated information along with the harvested content object in the search results so that when the search results are displayed, the generated information for the harvested content object is displayed in a substantially similar manner as when corresponding information is displayed for local content objects stored at the second repository.

17. The server of claim 15, wherein the retrieving of the metadata is performed using a modified version of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) protocol, the modified version comprising an Extensible Markup Language (XML) schema that extends metadata items provided in the OAI-PMH protocol to include the metadata associated with the learning content.

18. The server of claim 15, wherein the learning content comprises a Learning Management System (LMS) type of the content object.

19. The server of claim 18, wherein the processor is further configured to:

recognize the LMS type of the harvested content object as being the LMS type of the content object;

determine an action that can be performed for the harvested content object based on the LMS type; and

perform the action for the harvested content object.

20. The server of claim 19, wherein the LMS type comprises an assessment, and wherein the action comprises integrating the harvested content object into a LMS gradebook.
