Defining File System Content Publishing Rules

The File System Content Bridge uses Content Rules to define what is included in your content collection (published) and which indexsheets will process/index each type of document. Clicking on the button to the right of the Content Rules property field in the content collection properties window displays the Content Rules properties window in Figure 1.

You can set three content rules and a myriad of properties and values for any given document type. These three rules are:

• Publish
• Publish Content
• Index Sheet

The File System Content Bridge also allows you to set Property Values for each document type. See Property Values for information regarding these settings.

The content rules of Publish, Publish Document Content, and Index Sheet have the same meaning for all collection builder nodes. The NXT build system uses content rules to define how to create an NXT document from a source file. Content rules are based on document type. The File System Content Bridge provides you with a list of predefined document types and their rules. You can modify them to fit your needs.

For example, say you have the following rules and properties set for HTML documents:

• Publish: True
• Publish Document Content: True
• Index Sheet: HTML.xil
• Content Type (Property)
  • Property Source: Constant
  • Property Source Value: text/html
• Name (Property)
  • Property Source: Path
  • Property Source Value: FullName

This means that for any given HTML document that will be included in your content collection, the File System Content Bridge will create a table of contents entry for it (publish) and create a link on that entry to the HTML document's content or text for you to view (publish document content). NXT will index that HTML document with the HTML.xil indexsheet, and will associate the text/html MIME-type with the .htm or .html extension/document type. And, lastly, that HTML document will be identified within your content collection by its name value that comes from the document's name and extension (FullName).

You can assign many other property values to each document type than what the example illustrated.

Document Types

The File System Content Bridge uses file extensions to define and identify document types. At build time, the NXT build system publishes files based on the file's extension. The one exception to this is folders (directories). Use the document type "dir" when you define rules for folders. You can add new document types and define their respective rules by clicking on the "Add" button at the bottom of the "Members" area and using the document extension including the "." when you associate a rule with a document type. Table 1 shows the standard File System Content Bridge document types:
