The trend of e-Learning is changing, learning content has become the key issue of current e-Learning. We present a digital tool employing the component concept to design the learning object, which can help shorten and strengthen the reusable and interoperable of learning content.

In implementation, accorded with the Sharable Content Object Reference Model (SCORM) standard [1], constructs the manifest and metadata via component concept. Besides, the resource list using Application Data Objects (ADO) technology can communicate between the authoring tool and the learning object repository for previewing and downloading learning objects from the remote learning object repository.

Here, we develop a SCORM-compliant learning object authoring tool, including the friendly user interface. We can download learning resources from the remote learning object repository and we can add in manifest, on the other hand, we can describe learning content at the same time. Finally, compressing the learning resources and uploading to platform which ADL provides.
