Abstract

A method for use in an interactive information handling system which manages a relatively large plurality of electronic documents for a plurality of end users in which an end user who is not the owner of a document, may request a delayed copy of the document to be furnished only at the time that the owner'"'"'s copy of the document is to be deleted from the system. A Delayed Copy Request (DCR) is entered into the system interactively by the non-owner end user when a screen is displayed on the end user'"'"'s terminal. This screen prompts the end user for the information required by the system to subsequently present to the end user document owner. At the time the document is to be deleted, the information is redisplayed to the document owner which allows the owner to decide if the request should be honored.

Claims

1. In a multi-user interactive information handling system which maintains a relatively large plurality of electronic documents in storage for users of said system, in which each electronic document of said plurality is assigned at a time said electronic document is stored, an ownership label, a document label that identifies said electronic document by document type, said criteria that is used by said system to automatically delete said electronic document from said system at some future time, said criteria including first and second expiration dates, said system periodically processing said criteria of said electronic documents relative to a current date to cause said system to automatically delete a specific electronic document if a pre-established relationship exists among said current date and said first and second expiration dates assigned to said specific electronic document, a method to selectively provide a stored electronic copy of a first said electronic document owned by a first user to a second user in response to servicing a Delayed Copy Request from said second user at a time said first electronic document is to be automatically deleted from said system, said method comprising the following steps in combination,

A) assigning to said first electronic document said ownership label, said document label, and said criteria including said first and second expiration dates at the time said first electronic document is stored in said system including the interactive entry of at least one of said labels by said first user,

B) entering into said system interactively by said second user a Delayed Copy Request for said first electronic document.

C) periodically processing said criteria of said stored documents to determine if said pre-established relationship exists for said first electronic document.

D) servicing said Request with said system only at the time said first electronic document as determined in Step C) is to be automatically deleted from said system, including the step of selectively honoring said Delayed Copy Request, and

E) automatically deleting said first electronic document after said step of servicing is completed.

2. The method recited in claim 1 in which said step of servicing said Request includes the further steps of,

A) storing said Request in said system, and

B) making said copy of said first electronic document only at a time said first electronic document is to be deleted from said system.

3. A method for managing retention and automatic deletion of documents in an interactive information handling system including a plurality of end users and a plurality of interactive interconnected end user terminals which operate to enter and selectively display electronic documents stored in said system, in which a first end user enters a Request for a copy of a first electronic document owned by a second end user, which Request is subsequently serviced by said system only in response to detecting that said first electronic document is to be automatically deleted from said system, said first electronic document having a pair of expiration dates that are assigned to said first electronic document at a time said first electronic document is stored, said method comprising the following combination of steps;

A) periodically processing with said system said expiration dates assigned to said first electronic document relative to a current date to determine if a pre-established relationship exists among said dates,

B) storing said Request in said system,

C) determining with said system that said pre-established relationship exists among said current date and said dates assigned to said first electronic document,

D) servicing said Request by providing a copy of said first electronic document to said first end user, when said pre-determined relationship exists, and

E) deleting said first electronic document after said servicing step.

4. The method recited in claim 3 including the further step of,

A) said second user issuing a command interactively to said system prior to a time said predetermined relationship exists, requesting said first electronic document be deleted from said system.

5. The method recited in claim 4 further including the step of,

A) said first end user interactively entering said Request into said system by means of one of said terminals.

6. The method recited in claim 5 in which said step of interactively entering said Request includes the step of,

A) displaying to said first end user a screen which prompts said first end user for information required by said system to implement said step of servicing.

7. The method recited in claim 6 including the further step of,

A) displaying to said second end user when said first electronic document is to be deleted, a screen setting forth information to enable said second end user to decide how said Request from said first end user should be serviced.

8. The method recited in claim 7 including the further steps of,

A) servicing said request by

(1) making an electronic copy of said specified document for said first end user and,

(2) deleting said first electronic document after said copy is made.

9. The method recited in claim 8 in which said system includes a third end user and said method further includes the step of,

A) interactively entering a second Request for said first electronic document by said third end user through one of said terminals, and

B) said step of servicing includes servicing said second Request by,

(1) making another copy of said specified document for said third end user, and

(2) delaying said step of deleting said first electronic document until after said another copy is made.
