Document profiles offer a way to add searchable information pertaining to a document. This information can help describe or identify the document more clearly. By default, a profile includes basic properties such as Author and Title. You can easily add custom properties such as Account Number or Project Manager to capture additional information that makes it easier to organize and find documents in your organization.
Microsoft Office SharePoint Portal Server 2003 associates every document in the backward-compatible document library with a document profile that contains a set of properties. You create and store document profiles in the Document Profiles folder located in the Management folder.

SharePoint Portal Server bases all document profiles on a template. This Base Document profile contains general properties, such as title and keywords, which are applicable to all documents. If necessary, you can override these basic properties so that they do not appear on other document profiles that you create.
Depending on the needs of your organization, you can create many different document profiles. You can also override the settings on the default document profile. If you create and apply document profiles to folders in the document library, users can use the profile form to provide additional information about documents.
Note You can use document profiles to determine which documents are stored in a folder. You can allow users to store only documents with specific document profiles in certain folders.
