Abstract

Publishing to a publicly-accessible wide area network an availability file containing information on an individual'"'"'s availability to attend a proposed meeting. A user input, indicating the occurrence of an event, is accepted. Availability information is parsed out of the user input and published to an availability file located on a file server connected to a publicly accessible wide area network. The availability file is maintained in a commonly-recognized file format. Others can access the availability file over the publicly-accessible wide area network to ascertain the user'"'"'s availability to participate in a proposed event, such as attendance of a proposed meeting. These parties, however, do not have access to the user'"'"'s details of the occurrence of the event.

Claims

1. A computer readable medium having computer-executable instructions for making availability information associated with a schedule file accessible to others without giving access to the schedule file, comprising:

receiving, at a first calendar engine module, a first event input indicating the occurrence of an event for a user of the calendar engine module, the first event input comprising a start time for the first event, a duration for the first event, and a tentativeness identifier for the first event;

in response to receiving the first event input, instructing the calendar engine module to place the first event input in the schedule file, wherein the schedule file is maintained on a local machine that is not publicly accessible;

instructing the calendar engine module to parse the first event input for availability information comprising the start time for the first event, the duration of the first event, and the tentativeness identifier for the first event;

from the calendar engine module, forwarding the availability information to a publisher engine module;

in response to receiving the availability information, instructing the publisher engine module to create an availability file comprising the availability information;

wherein the availability file is stored in a non-proprietary format;

instructing the publisher engine module to publish the availability file to a server machine which is publicly accessible; and

scheduling, at a second calendar engine module, a second event by accessing the availability file to determine the tentativeness identifier and, based on the tentativeness identifier, determining whether the user is likely to be available to attend the second event.

2. The computer readable medium of claim 1, wherein the step of placing the first event input in the schedule file further comprises writing contents of the event input to the schedule file and maintaining the schedule file on a permanent storage medium separate from the server machine.

3. The computer readable medium of claim 1, wherein the non-proprietary format is American Standard Code for Information Interchange (“

ASCII”

) text format.

4. The computer readable medium of claim 1, wherein the availability file comprises a plurality of records, each record containing the start time, the duration, and the tentativeness identifier of a different event input.

5. The computer readable medium of claim 1, wherein the step of publishing the availability file comprises transmitting the availability file to the server machine connected to a publicly-accessible wide area network.

6. The computer readable medium of claim 5, wherein the availability file is published to the server machine using a file transmission protocol selected from a group including a File Transfer Protocol (“

FTP”

) and a HyperText Transfer Protocol (“

HTTP”

).

7. The computer readable medium of claim 6, wherein the server machine comprises a permanent storage medium separate from the local machine.

8. A computer readable medium having computer-executable instructions for planning a meeting having a proposed attendee, comprising:

accepting, at a calendar engine module, a first input indicating a request to plan the meeting;

accepting, at the calendar engine module, a second input that identifies the proposed attendee;

in a background thread, retrieving an address indicating a publicly accessible location of an availability file containing availability information associated with the proposed attendee, the availability information comprising a start time for an event of the attendee, a duration for the event of the attendee, and a tentativeness identifier for the event of the attendee and the availability file being in a non-proprietary format;

accessing, at a publisher engine module, the availability file at the publicly accessible location to retrieve the availability information associated with the proposed attendee;

providing, at the calendar engine module, the availability information associated with the proposed attendee in a form that enables planning the meeting at a time when the proposed attendee does not have a scheduling conflict; and

scheduling, at the calendar engine module, the meeting by accessing the availability file to determine the tentativeness identifier and, based on the tentativeness identifier, determining whether the user is likely to be available to attend the second event.

9. The computer readable medium of claim 8, wherein the step of retrieving the address further comprises accessing a registry file containing a plurality of records, wherein one of the plurality of records comprises a first identifier corresponding to the proposed attendee and a second identifier corresponding to the address.

10. The computer readable medium of claim 8, wherein the publicly accessible location of the availability file comprises a file server connected to a publicly-accessible wide area network.

11. The computer readable medium of claim 8, wherein accessing the availability file is performed using a file transmission protocol selected from a group including a File Transfer Protocol (“

FTP”

) and a HyperText Transfer Protocol (“

HTTP”

).

12. A computer-readable medium having computer executable modules, comprising:

a user interface module operative for receiving an event input defining an event, the event input comprising a start time for the event, a duration of the event, and a tentativeness identifier for the event;

a calendar engine module operative to parse the start time, the duration, and the tentativeness identifier in response to receiving the event input from the user interface module, write the event input to a schedule file maintained at a location which is not publicly accessible, and transmit the start time, the duration, and the tentativeness identifier;

a publisher engine module, responsive to the start time, the duration, and the tentativeness identifier transmitted by the calendar engine module, operative to write the start time, the duration, and the tentativeness identifier to an availability file maintained at a first publicly accessible location to make the start time, the duration, and the tentativeness identifier publicly accessible; and

the publisher engine module further operative to access a remote file located at a second publicly accessible location over a publicly accessible wide area network containing the start time, the duration, and the tentativeness identifier and to access the availability file to determine the tentativeness identifier and, based on the tentativeness identifier, determining whether the user is likely to be available to attend a meeting.

13. The computer-readable medium of claim 12, wherein the availability file further comprises

a header containing data representing an individual associated with the availability file and the number of days for which the availability file is valid.

14. The computer-readable medium of claim 13, wherein the start time comprises the date on which the event will occur.
