You use the Developer to create, maintain, and publish your content Library. A typical content Library can contain hundreds, if not thousands, of documents. You can organize the Library using folders (similar to the way Windows Explorer lets you organize files on your computer). The main difference between Windows Explorer and the Library is that documents are stored in a relational database and not as individual files on a disk drive. However, this difference is largely transparent to you as you develop your content.
To help you visualize your content as you build it, the Developer offers various displays:
The Library shows the entire content repository and its organization in folders. Each folder displays the documents that it contains or other folders and their corresponding documents. This folder structure is completely defined by an author. A System folder structure is also created during installation that contains various system-wide documents for assessment and question templates, publishing styles, topic text templates, roles, and attachment icons.
Document editors display the content of a single document in an editor. Each document editor appears in a new tab as you open or create documents. The document editor that appears depends on the type of document that you create or open.
