Windchill System Administrator's Guide

Overview of Content Holders
A number of Windchill information objects, including all document types and
change objects (change requests, change orders, and change activities), are
modeled as content holders. A content holder is an object to which files and URLs
can be attached. For example, when you create a Windchill document object and
save it to the Windchill database, files and URLs can be added to the object. The
files and URLs are then uploaded to the database or to an external file vault. For
information about file vaults, see Administering External File Vaults.
Content can be uploaded to and downloaded from content holder objects in the
following ways:
• Through HTML forms/hyperlinks
• Through Java applets making RMI calls
• Through a SOAP implementation such as Windchill Desktop Integration 2.0.
The content attached to a Windchill object can later be viewed, downloaded,
removed, or replaced with new or updated content, subject to user permissions
and the status of the Windchill object.
All content holder objects can have unlimited content attachments, but only
FormatContentHolder objects can have a primary content attachment in addition
to their unlimited secondary content attachments.
Content can be replicated to increase the productivity of Windchill users. For
information about content replication, see Administering Content Replication.
This chapter describes the following:
• Content Handling Configuration
• Adding and Updating Data Formats (which define MIME types for
downloading content objects)
