Interface Document

All Known Subinterfaces:: DocumentRemote

public interface Document
extends Content

The public interface for a Document.

This is the base interface for Document objects. In general, you should only typecast to this interface and not to the DocumentRemote EJB interface.

Documents are a specialized type of Content which are generally controlled by a Document Management System (DMS). The Document interface contains explicit attributes common to most types of documents and DMS's. Additionally, the Document interface has a method to retrieve the raw bytes of the actualy document itself (e.g. the images data of a GIF, the text of an HTMl document. Document's inherit the identifier and mimeType attribute from the Content interface. Also, all other implicit attributes (i.e. metadata) about the document will be available.

The reference implementation document management system included in the PersonalizationServer2.0 does not support creation or modification of Documents via the EJB interfaces. However, other implementations might.

 Primary Key = com.beasys.commerce.axiom.document.DocumentPk

Attribute: description

Containment: By Value
Multiplicity: 1:1
This is the text description of the doucment from the DMS.

Attribute: size

Containment: By Value
Multiplicity: 1:1
This is the size of the document's files in bytes. If this is 0 or less, than the document doesn't have bytes and is represented entirely within the metadata.

Attribute: modifiedBy

Containment: By Value
Multiplicity: 1:1
This is the identifier of who last modified the document.

Attribute: modifiedDate

Containment: By Value
Multiplicity: 1:1
This is the time/date of when the document was last modified.

Attribute: creationDate

Containment: By Value
Multiplicity: 1:1
The date upon which the document was created.

Attribute: version

Containment: By Value
Multiplicity: 1:1
The version number of the document.

Attribute: author

Containment: By Value
Multiplicity: 1:1
The identifier the author of the Document.

Attribute: lockedBy

Containment: By Value
Multiplicity: 1:1
The identifier of who has the document locked in the DMS.

Attribute: comments

Containment: By Value
Multiplicity: 1:1
Any comments associated with the document.

Attribute: name

Containment: By Value
Multiplicity: 1:1
The name of the document, which generally corresponds to the original file name.

When constructing queries for Documents, the above property/attribute names will compare against the explicit attributes on the Document interface. For example, to find document whose size is less than 1024 bytes, you could use a query string like "size < 1024".
