Creating the Section Record and Alias Record

Your application is responsible for creating a section record and an

alias record for each publisher and subscriber section within an open

document.

The section record identifies each section as a publisher or subscriber and

provides identification for each section. The section record does not contain the

data within the section; it describes the attributes of the section. Your

application must provide its own method for associating the data within a

section with its section record. Your application is also responsible for saving

the data in the section.

The alias field of the section record contains a handle to its alias record. The

alias record is a reference to the edition container from the document which

contains the publisher or subscriber section. You should be familiar with the

Alias Manager's conventions for creating alias records and identifying

files, folders, and volumes to locate files that have been moved, copied, or

restored from backup.

When a user saves a document, your application should store all

section records and alias records in the resource fork. Corresponding

section records and alias records should have the same resource ID. This

allows compatibility for future changes.

The Figure below shows a document containing a publisher and subscriber,

and the corresponding section records and alias records.

The SectionRecord data type defines the section record. A section record

contains information to identify the data contained within a section as a

publisher or a subscriber, a time stamp to record the last modification of the

section, and unique identification for each section.
