Abstract

Often times an item becomes obsolete within a user's personal calendar. In particular, the user may have hundreds of obsolete or erroneous entries posted on his/her calendar. The calendar entry may have certain conditions associated to the event. Consider a registered meeting event between a sales representative and a particular customer. Moreover, consider the company transferring the sales representative from handling that particular customer's account. Thus, there is a desire to find and delete all calendar entries for which the account is the subject AND the customer's identity is the originator. Enterprises desire predicate deletion operations within their electronic calendar facility. Prior art does not provide a methodology for predicate deletion of entries within an electronic calendar system.

Method for Predicate Deletion of Calendar Events

      Often times an item becomes obsolete within a user's personal
calendar.  In particular, the user may have hundreds of obsolete or
erroneous entries posted on his/her calendar.  The calendar entry may
have certain conditions associated to the event.  Consider a
registered meeting event between a sales representative and a
particular customer.  Moreover, consider the company transferring the
sales representative from  handling that particular customer's
account.  Thus, there is a desire to find and delete all calendar
entries for which the account is the subject AND the customer's
identity is the originator.  Enterprises desire predicate deletion
operations within their electronic calendar facility.  Prior art does
not provide a methodology for predicate deletion of entries within an
electronic calendar system.  It is advantageous to provide a method
and apparatus for allowing predicate deletion of calendar entries.
In addition, users may desire to have entries designated for
deletion, thus allowing the user to preview and select calendar
entries for user confirming deletion of calendar entries.

      This article describes a mechanism and methodology for handling
predicate deletions of calendar entries.  Upon a user requesting a
deletion of an entry, a Predicate Deletion Service performs boolean
search operations on the calendar's data base.  Conditions for
deletions can be specified by the user via typical user interface
techniques.  These techniques, however, would allow the user to
specify the conditions for which an event should be deleted.
Conditions also can be specified for which an event should be
excluded from deletion.  In addition, events specified for deletion
need not be contextual deletions.  A contextual deletion is a delete
operation in which derivation of the predicate conditions are from
the content of the entry.

      Parametric deletions are deletions derived based on information
outside the scope of the content itself, for example, deletions based
on the subj...
