The Learning Object Repository (LOR) in the Desire2Learn system is an online archiving tool. Your course syllabus must be archived for future reference. In the D2L system you have a simple way to publish it to the LOR for archiving.
Navigate to the Manage Content area of your course where you have uploaded the course syllabus, and then follow the instructions that I provide in the video. You may also download the instructions as a document (in .pdf) via the link at the bottom of this post.
