Abstract
Abstract The present invention discloses an architecture for document archival built on network-centric groupware such as Internet standards-based messaging. Archiving and retrieving and classifying documents into meaningful collections is accomplished in a manner similar to sending email to recipients, retrieving messages from folders, and classifying messages into folder hierarchies. In the simplest scenario, if saveme.com is the archiving server's name, then sending an email to abc@saveme.com will cause the contents of the email message to be archived in the abc mailbox. The archived documents may be automatically stored in jukeboxes of non-tamperable media such as Write Once Read Multiple (WORM) Compact Disks (CD), which provide high storage capacity, low cost compared to magnetic disks, random data access, and long-term stability. The present invention leverages existing messaging infrastructures, and the resulting environment is not intrusive, easier to administer, and easier to deploy than conventional dedicated document archival systems.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
103 words
A computer readable medium containing executable program instructions for performing a method of archiving electronic documents on a computer comprising the steps of: receiving a document via a messaging protocol, the document being an attachment to an electronic mail; determining to which mailbox on a server the document is addressed; and automatically archiving the document if the mailbox is designated as an archive folder, the archiving comprising the steps of: storing the document on a storage device; deleting the document and the electronic mail from the mailbox; and storing a message in the mailbox comprising an address enabling access to the stored document.
Claim 2
Dependent Claim
103 words
A computer readable medium containing executable program instructions for performing a method of archiving electronic documents on a computer comprising the steps of: receiving a document via a messaging protocol, the document being an attachment to an electronic mail; determining to which mailbox on a server the document is addressed; and automatically archiving the document if the mailbox is designated as an archive folder, the archiving comprising the steps of: storing the document on a storage device; deleting the document and the electronic mail from the mailbox; and storing a message in the mailbox comprising an address enabling access to the stored document.
Claim 3
Dependent Claim
17 words
The computer readable medium of claim 1 wherein the messaging protocol is the Simple Message Transfer Protocol.
Claim 4
Dependent Claim
22 words
The computer readable medium of claim 1 wherein the message in the mailbox can be accessed by the Internet Message Access Protocol.
Claim 5
Dependent Claim
24 words
The computer readable medium of claim 1 wherein the address is a URL to a script which retrieves the document from the storage device.
Claim 6
Dependent Claim
28 words
The computer readable medium of claim 1 further comprising the step of storing document attributes and a location of the document on the storage device in a database.
Claim 7
Dependent Claim
21 words
The computer readable medium of claim 1 wherein the storage device is an optical media jukebox with a magnetic disk cache.
Claim 8
Dependent Claim
71 words
An electronic document archival system comprising: a hierarchy of addressable folders; and a system for receiving electronic mail via a messaging protocol further comprising: means for archiving documents addressed to a folder in the hierarchy, the archiving means further comprising means for extracting a folder path in the hierarchy from an electronic mail; and means for enforcing access control restrictions that apply to the folders or the contents of the folders.
Claim 9
Dependent Claim
71 words
An electronic document archival system comprising: a hierarchy of addressable folders; and a system for receiving electronic mail via a messaging protocol further comprising: means for archiving documents addressed to a folder in the hierarchy, the archiving means further comprising means for extracting a folder path in the hierarchy from an electronic mail; and means for enforcing access control restrictions that apply to the folders or the contents of the folders.
Claim 10
Dependent Claim
25 words
The electronic document archival system of claim 7 wherein the system is a messaging system and the folders are public folders in the messaging system.
Claim 11
Dependent Claim
25 words
The electronic document archival system of claim 7 wherein the system is a proxy server in communication with a messaging system via a messaging protocol.
Claim 12
Dependent Claim
18 words
The electronic document archival system of claim 7 wherein the system is fully integrated with a messaging system.
Claim 13
Independent Claim
72 words
A method of archiving documents on a durable medium comprising the steps of: storing the documents in a cache; assigning to each document a clustering value; sorting the documents according to the clustering values; when the cache overflows, selecting based on the clustering values a subset of the documents with a total size no larger than that of the durable medium and storing the subset of the documents on the durable medium.
Claim 14
Independent Claim
72 words
A method of archiving documents on a durable medium comprising the steps of: storing the documents in a cache; assigning to each document a clustering value; sorting the documents according to the clustering values; when the cache overflows, selecting based on the clustering values a subset of the documents with a total size no larger than that of the durable medium and storing the subset of the documents on the durable medium.
Claim 15
Dependent Claim
14 words
The method of claim 11 wherein the clustering value comprises a document expiration date.
Claim 16
Dependent Claim
16 words
The method of claim 11 wherein the subset is shortest with respect to the clustering values.
Claim 17
Dependent Claim
14 words
The method of claim 11 wherein the durable medium is an optical compact disk.
